Bucket: First thing's first, my name is no longer SeeUinHell, which is potentially offensive! (Insert enthusiastic/positive cheers and claps) I'm now called SpareBucketTurtle because I'm slow (as you may be able to tell) like a turtle and empty minded like a bucket. And I am spare labor so there. SECOND of all, I offer to all of you my most sincerest apologies, because...well, shit, I'm a horrible person, aren't I? Making everyone wait this long? I take all the blame for the wait. I first used school as an excuse, then laziness in the summer, then school again, then tests, essays, etc. I mean, we planned to have a new chapter out when the anime first came out, but then (insert excuses). Yuki's the responsible one. She's the one who kept reminding, pressuring, and pestering me to work on this, since she's the idea maker (not empty like me) and I'm the main writer (typer?). Anyways, I will receive all those yells and insults and 'finally!'s because I deserve them. Again, I'm am so, so sorry...Okay, Yuki's turn.

Yuki: I should also apologize for not pressuring [threatening] her enough to get her to work. But I have to say that school did have a big role in why it's so hard to work anything other than school work, it was even hard to hang out with friends. We do have our ideas and such written out so no worries about the excuse of "I don't know what to write" but it's more of an "I don't feel like writing" or "I don't know how to word this". BUT! I really hope that you enjoy and like this chapter as much as Bucket and I do.

Bucket: Also, thanks to the reviewers that supported our story, even if most of them consisted of variations of 'update'. I am absolutely amazed that a single chapter received this much fanfare. Sorry for this favoritism, but I have to admit that Superbi Squalo's in character review actually encouraged me to work on this. (There's also that 'It's been a year and seven months' reminder, though by now it's been eight months, so yeah, that thing helped…)

Summary (Again, because of those poor mobile readers): To kill an octopus, you need help from the mafia. Seriously. That's why Sawada Tsunayoshi, Vongola Decimo, will be assigned to teach the students of Class E to do exactly that. (Does that thing even have eight legs?)

Chapter 2: Sawada-sensei

Tsuna hated rainy days. No offense, Takeshi, Tsuna thought as he trudged up the mountain. He lamented the thought of cleaning the mud off the bottom of his shoes. He determinedly ignored the voice in his head reminding him to never let Reborn find out that his outfit was being anything less than spotless. Nonetheless, it was inevitable that at least a few drops of water soaked into his suit. Even with his expert umbrella wielding skills, Tsuna was sure even Reborn wouldn't be able to dodge every drop. So there, Tsuna pouted petulantly in his mind as he pulled his umbrella lower. But he would still need to get rid of any trace of mud because the brunet was sure his not-so-former tutor would pull off a surprise visit and would definitely punish him if-when-he found out about the mud.

Tsuna shook his head with a shudder. No, he told himself, he couldn't be distracted. He had a class to teach.

Tsuna soon arrived at Class E's building, only to see a large group of teenagers smiling and laughing despite the dreary atmosphere. Unfortunately, this didn't help Tsuna's own mood. He needed coffee. Badly. Anything to get rid of the smell of petrichor. He dragged himself into the old school building and made a beeline for the teacher's lounge, not caring that he seemed very rude for not returning the students' greetings. Reborn's going to kill me for these horrible manners, Tsuna grimaced. Yet another thing Reborn would pick on him for. Automatically, his arm reached for the jar of coffee powder as he started to boil water in the electrical kettle. He sat down, his left leg fidgeting and his right hand tapping against the side of the chair as he waited with anticipation for the water to finish boiling. Minutes later, the brunet heard the click of the machine finishing its job and stood up immediately. He poured the hot water into his cup and began stirring.

"You really love your coffee, don't you?"

The only thing that kept Tsuna from jumping around was the fact that he would've spilled the burning liquid on himself. Instead, he slowly turned around. Karasuma stood in the doorway, leaning against the frame with his arms crossed. "Hn," Tsuna grunted, not caring that he sounded a lot like his Cloud Guardian.

"Not a morning person, I take it?" Karasuma asked as he pushed himself off the frame into the room, moving to prepare his own cup.

Tsuna took a long sip of his drink in response, feeling satisfied as warmth filled him. "Yes," he replied. "Especially with the rain. The cold air makes me feel very...stiff and tired."

"I'll help you with that!" Tsuna felt something massaging his shoulders, and he looked up to see a giant yellow head. He did drop his cup of coffee this time, but Koro-sensei's Mach 20 speed caught the cup with all of its contents still inside it. Tsuna had been caught off guard, and the wide grin on the octopus's face did not help his nerves one bit.

"K-Koro-sensei," Tsuna almost yelped, but his pride kept him from doing so. "I'm fine. Just fine." He stepped away, taking back his cup. "Coffee is enough for me." He paused. Koro-sensei looked downtrodden, like a child whose favorite toy was taken away. "Thank you, though," he added. Koro-sensei brightened. Like a child, indeed.

"What exactly do you intend to do here, Sawada-san?" Karasuma asked, eyeing Tsuna calculatingly. Tsuna knew that look. Karasuma was trying to figure out what exactly Tsuna would be able to contribute to this special classroom. "You were observing the whole day yesterday. What do you think they need to work on?"

Tsuna sighed inwardly. No matter how open-minded Karasuma was, he was still suspicious of the mafioso taking on a government job. He was blatantly trying to reveal Tsuna's 'true' personality as well as silently challenging Tsuna, asking what he was going to do about it. I never want to make this guy my enemy, Tsuna prayed in his mind to any deities that would listen, for Tsuna could recognize how capable a fighter and strategist Karasuma was. But then again, Karasuma was part of the government, the law, and therefore already an enemy. Tsuna fought the urge to slap his hand to his face.

Tsuna instead forced a slight smile on his face, earning an irritated eye twitch from the dark haired man. So Karasuma was the type of person who appreciated seriousness when the situation called for it. Tsuna could easily infer that this was Jelavic Irina's (Or was it Irina Jelavic since she wasn't Japanese?) fault, considering the way she introduced herself to Tsuna the day before. Yes, if his only co-workers were the immature Koro-sensei and flirty Jelavic, then no wonder Karasuma would immediately assume Tsuna's attempt to maintain a pleasant personality was an act of mocking his question. Tsuna respected Karasuma though, for being able to put up with all of Koro-sensei's, Jelavic's, and the government's shit, so he wouldn't call the man out on that assumption and answer honestly. "As I said yesterday, I will teach the students whatever they want me to teach, as well as whatever needs to be taught." Tsuna stopped for a moment to take a sip of much-needed coffee. "Of course, while I am willing to help with academic subjects, I'm sure Koro-sensei has them well covered," he stated dryly.

Said octopus-like teacher laughed in what he probably thought was an evil way, rubbing his hands (Tentacles?) together with a "Nurufufufu!" Tsuna was glad that despite the similar laugh, Koro-sensei was nothing like his male Mist Guardian.

"And Karasuma-sensei is setting the foundations of the students' combat ability," Tsuna continued, tilting his head towards the man in acknowledgment. "I can see that the students are only just warming up to Jelavic-san-" Tsuna hid a smirk by taking a sip of his coffee when Karasuma's eyebrow rose in surprise at Tsuna's accurate insight. He set the cup back down on the table. "-so I can help with languages. I know quite a few myself. But I believe I can best help when it comes to specialties."

"Specialties?" Koro-sensei echoed. Tsuna didn't know how, but Koro-sensei's beady eyes managed to narrow with interest.

Tsuna gave a thin smile. "As I said yesterday," he repeated. "Whatever they want to learn, what they want to specialize in, what they're passionate about." The faint noise of the starting bell from the main Kunugigaoka building could be heard in the distance. Tsuna stood up from his seat, eyes narrowing. "As well as anything necessary." The familiar sensation of his Dying Will Flames burned inside him as his eyes flashed orange for a split second. "Anything."

-To Kill an Octopus-

In the corner of his eye, Nagisa caught sight of the class's new assistant teacher entering the room. Sawada-sensei didn't look like he could kill anybody. He had wide does-like brown eyes and fluffy brown hair that made him look (dare he say it) like a small animal, especially considering his short stature for his age. Not only that, but Sawada-sensei looked oddly out of place in a suit.

Was he teaching them this morning?

"Tsuna-kun!" Bitch-sensei called out excitedly as she entered after the man. "Are you teaching with me today?"

"I'll be helping," Sawada-sensei corrected, a strained smile on his face. He moved off to the side of the classroom, leaning against the wall as he observed the class.

An elbow suddenly jabbed into Nagisa and he bit back a yelp. He turned to see Kaede rub the back of her neck sheepishly, mouthing an apology. She leaned over from her seat. "What do you think of him, Nagisa-kun?" she whispered.

Nagisa shrugged, taking out his notepad where he wrote all of Koro-sensei's weaknesses. He flipped it all the way to the last page, considering whether or not he should start a list of facts they knew about Sawada-sensei in case he turned out to be another two-faced person like Bitch-sensei had been. After all, he was still a complete mystery to them. "He seems nice," Nagisa told the green haired girl. "But Sawada-sensei could be pretending. He doesn't seem to be against us learning anything like other adults are, though."

Tomohito leaned forward from his seat behind Nagisa. "Maybe he's also only after the money, but unlike Bitch-sensei, he intends to use us and take all the credit. Kinda like what Terasaka did with you." Nagisa flinched at the reminder.

"Oi, quiet down and sit, brats!" Bitch-sensei shouted at the class, personality a complete one-eighty from when she was speaking with Sawada-sensei. "Today, we're continuing with English! It's the language the whole world would agree is the main language. It's on a need-to-know basis if you're going to be an assassin."

The class proceeded to learn about the differences between 'L's and 'R's, 'B's and 'V's, and more at the risk of Bitch-sensei's lips. However, Nagisa did think the dramas Bitch-sensei showed them, despite the fact that they were all about sex and seduction, were rather helpful. Unfortunately, Bitch-sensei became very frustrated when Kimura was unable to differentiate the 'L' and 'R' sound of the word English word 'really'.

"Tsuna-kun!" Bitch-sensei practically whined, and really, that behavior wasn't unexpected considering her personality. "You can say it, right? Can't you help me make them do it right?"

Sawada-sensei had been staring off into space out the window when his name was called, causing his head to jerk up almost comically when he came into attention. The startled expression was quickly covered up with a small smile. "Of course," Sawada-sensei answered smoothly as if he had never been distracted. "'Maji de', in English is said as 'really'. In a sentence, 'You all really need to learn English,' which translates to 'You all really need to learn English'."

Silence resounded in the classroom.

Sawada-sensei blinked. "Is...Is something wrong?"

The class erupted into murmurs of compliments at his English, how fluent he was, how his Japanese accent didn't show at all. Even Bitch-sensei was visibly impressed.

"Not bad at all, Tsuna-kun," she commented. "How long did it take you to get to this point?"

"Well, I was never the best student," Sawada-sensei admitted easily. "But I was forced to truly learn five years ago when I went to visit England. I was told to lose the accent or else-" He cut himself off, looking unsure of whether or not he should finish that sentence. He eventually decided not to, as he continued with, "Anyways, English comes easily to me now." He paused to think. "As does Italian, Russian, French, Spanish, German, and Chinese." He ducked his head when the class gasped. "I'm not as fluent in half of those, though," he added, trying to be modest. It didn't help.

"Are knowing a lot of languages really that necessary for being an assassin?" Hinano asked, dispirited because she wasn't having the best luck with learning a second language.

"N-No! No, not at all!" Sawada-sensei blurted out with wide eyes as if just realizing how discouraging his words might have sounded like. "There are different kinds of assassins," he was quick to explain. "Every assassin has their own specialty. Of course, to most civilians, the first thing that comes to mind is someone wearing dark clothes who sneaks up behind people with a knife, correct?" He earning some sheepish nods. "In truth, assassins, the more professional they are, the less need they have to sneak in the shadows." He paused for a moment to let the fact soak in. "As I was saying before, all assassins have their own specialty. For example, the Poison Scorpion uses what is called 'Poison Cooking'. The food she makes is quite literally toxic. Then there's Moretti the Murdered, who is famous for playing dead and catching his targets off guard. Because of this killing method, practically no one actually knows who he is. The infamous Trident Shamal doesn't even need to come into contact with those he assassinates. He uses disease holding mosquitos that have a trident-shaped stinger, which is what he's named after. As you can see, their weapons of choice are all unique. They usually use what feels most comfortable or what they're most confident with.

"That's what I'm here for," Sawada-sensei raised his voice to make sure everyone in the classroom heard, and Nagisa didn't miss the way all his classmates' backs straightened at his authoritative tone. "I'm not here to make sure you pass this class, and I'm not here to assist in killing Koro-sensei. I'm here to help you find and improve the skills you already have and turn them into efficient weapons. I'm here to ensure that none of you let those weapons go to waste." His dark brown eyes seemed to burn into a deep amber color. If the afternoon sun wasn't shining through the windows behind the man, Nagisa would've sworn his eyes were glowing. "And most important of all, I'm here to see that you all will survive." The sheer determination laced through that single word sent shivers up Nagisa's spine. In the corner of the blue-haired boy's eyes, he caught sight of Karma reacting similarly, before leaning forward with a fascinated expression. Just that motion caused a second jolt of something run through Nagisa's body, for in this moment, he didn't know whether he should fear for Sawada-sensei, or for Karma. Forcing himself to focus his attention back on Class-E's new teacher, Nagisa watched as the whole image (bright and strong and filled with purpose) broke with a single blink. Orange eyes disappeared and the sun no longer shined at the right angle to produce the same image. Sawada-sensei's previously piercing gaze now flickered between students with an uncertain air. "Erm... Are there any more questions?"

-To Kill an Octopus-

"Sawada-sensei's really weird, isn't he?"

Nagisa glanced up to see Hiroto approach and take a seat next to him under the tree Nagisa ate lunch at every day. Tomohito was taking a nap in the shadow of a tree on the other side, and Karma was sitting up in a branch doing who-knows-what. So Nagisa took it in stride when Hiroto stretched out his legs and rested his hands behind his head, leaning against the trunk of the tree. "What do you mean, Maehara-kun?"

"Well," Hiroto mused, "He's all wimpy at first, then he turns all serious like Karasuma-sensei, then he goes back to being a wimp! It's like he can't decide on whether he wants to be badass or a loser."

Nagisa sweatdropped at his classmate's choice of diction. "Well, at least he's not like a second Bitch-sensei."

As if on cue, they could hear Sumire's voice call out loudly from the classroom. "See you after lunch, Bitch-sensei!" The shouted retort from Bitch-sensei was full of insults and swear words.

A scoff came from above them. Karma peered down at them with a smirk. "Don't write Sawada-sensei off just like that. If Bitch-sensei wasn't as one-sided as she seemed, what makes you think Sawada-sensei will be as well? Besides, the wimpiness and badassery you were talking about? That personality change is proof that he's more than he seems." A feral grin grew on his face. "It's just a matter of seeing if the wimpiness makes him weak and if the badassery makes him strong." Karma tilted his head towards the classroom to gesture at the teacher in question, who had propped open the window of the teacher's lounge to survey the students. A slight frown pulled his lips down as his eye's flickered from one end of his vision to the other as if he were looking for something.

"What're you guys looking at?"

Hiroto yelped and even Nagisa jumped at Yuuma's sudden appearance. Yuuma huffed out a laugh and Karma snickered at their reaction. "Isogai-kun, please don't do that," Nagisa admonished, hand over his heart. Then he added, "And we're talking about Sawada-sensei. He seems nice, and a little uncomfortable about being around all of us. But he changes completely sometimes, so we're wondering which side of him is real or fake, like how Bitch-sensei acting really nice in front of Koro-sensei was fake."

"Huh." Yuuma dropped down to the ground and sat with his legs crossed. "I think both sides are real." Hiroto sent him a skeptical expression while Karma looked over with interest and Nagisa flipped open his notepad to take notes. The more information Nagisa could gather on how everyone saw Sawada-sensei, the surer he could be on what kind of person he really was. They'd need as much ammunition as possible against him if Sawada-sensei turns out to be someone trying to hinder their education and assassination.

"I mean it," Yuuma addressed Hiroto's skepticism. "Sawada-sensei sounded like he honestly wanted to teach us. Why else would he promise anything? He even cheered Kurahashi-chan up when she was feeling discouraged even though he didn't have to! If he truly didn't care about being a teacher, he wouldn't have bothered doing that."

"Yeah, but he also said he'd be trying for the ten billion!" Hiroto voiced what Tomohito had proposed during class, refusing to believe Sawada-sensei wouldn't try to steal the bounty. "He said he'd be killing Koro-sensei 'indirectly', which probably means he'll get others to do the killing to not get his hands dirty, just like Bitch-sensei, only more open about his intentions."

Yuuma sent over a look that said, I question your intelligence, sometimes. "When he said 'indirectly', he meant will attack Koro-sensei through teaching us," he explained with patience. "Sawada-sensei seems like the type of person who wants work done right; therefore, he does the work himself. By teaching us well, we'd be able to defeat Koro-sensei. It's a win-win for both Sawada-sensei and us."

Hiroto was still dubious. "Why wouldn't he want part of the ten billion?" After all, no matter how much anyone denied it, money did help people go places.

Yuuma was stumped, so Nagisa picked up after him. "Maybe Sawada-sensei doesn't need the money? Koro-sensei can't be the only person with money on his head. Perhaps he was on another job before this? And wouldn't the government have set certain conditions before letting him teach us? They wouldn't let him take too much of the money if they let him take any at all," the blue haired boy pointed out. He received shrugs back from his classmates.

"Aaahh," Hiroto sighed and rolled over onto his stomach. "Whatever. I don't want to think about anymore. When the time comes and Sawada-sensei turns out to be Bastard-sensei to match with Bitch-sensei, we'll find a way to deal with it." And the conversation pretty much ended, moving onto another topic as Tomohito awoke.

But Nagisa exchanged glances with Karma before looking back over at where Sawada-sensei was turning away from the window. Orange eyes met blue for a split second and Nagisa couldn't help but hope that they would never have to 'deal' with Sawada-sensei.

-To Kill an Octopus-

Tsuna froze as the door of the room he was about to enter was roughly shoved open hitting the wall with a loud 'BANG'. Jelavic slammed the door back to a closed behind her and marched past Tsuna with an irritated expression, not even acknowledging his presence. Tsuna blinked, confused with her agitation, and slid the door open once more. He did so slowly and quietly, a big difference from when Jelavic exited. Tsuna entered the room to see Karasuma closing his laptop and shuffling through papers, clearly having finished up whatever work he had for the moment.

"Good afternoon, Sawada-sensei!" Koro-sensei chirped.

Tsuna smiled courteously back, now in a better mood to deal with the octopus now that it wasn't dreary and raining like it had been in the morning. "Good afternoon, Koro-sensei, Karasuma-san. And please, just calling me 'Tsuna' is fine."

Karasuma raised a brow at the familiar nickname Tsuna offered. "Good afternoon, Sawada," the serious man instead greeted.

"Tsuna-sensei it is, then!" Koro-sensei easily accepted. "I'm going to Shanghai for some almond jelly. Would you like me to get you some since it's your first day as a teacher?"

Tsuna glanced over towards Karasuma, uncertain about how he should answer. The other man took it all in stride, not even looking up from his papers. "No, thank you," Tsuna finally said. "Is there anything I should do during the break?"

"Not much," Karasuma responded, standing up. He tucked his stack of papers into a folder and set it inside a desk drawer. "Do whatever preparations you think will be needed for your short class later this afternoon. Other than that, this is your lunch break as well, not just the students'."

"Oh, I see…" Tsuna had no idea what to do with this time. He had already prepared for his class before he left his apartment. It was a habit ingrained in him by Reborn to have at least a vague schedule if nothing else set in his head, not that it would be hard to think up of a lesson on the spot. But as it was the first day, an introduction to assassination, in general, would be enough, and he wanted to get to know the students by asking about what interests each one had. Doing that would also bring him a step closer to helping the students find the right weapon.

"Well, then. See you later, Sawada," Karasuma nodded curtly and took his leave, not deigning to give Koro-sensei another look.

Koro-sensei didn't seem to be offended at all. "I'm off too! Let me know if you need anything, Tsuna-sensei!"

Those were the words Tsuna was waiting for. "Actually, Koro-sensei, there was something I've been thinking about for quite a while." Koro-sensei's yellow skin faded into a pastel blue, delighted that he could be of some help. "Why exactly are you trying to destroy the world?" Tsuna had asked it innocently enough, and surely, he couldn't be the first person to ask.

Koro-sensei's bright blue dulled to a sick looking gray, but his usual wide smile never faltered. "Trying? I don't need to try to do anything. I will destroy the world."

It was obvious Koro-sensei didn't plan on answering that question, so Tsuna pressed on. "Then, what intentions do you have behind teaching this class if you're going to destroy the world anyway?"

Tsuna didn't need his Hyper Intuition to tell him that the tension between them suddenly skyrocketed when Koro-sensei didn't reply immediately. Yet...his Intuition was trying to alarm Tsuna of something. It has nothing to do with Koro-sensei, Tsuna was quick to deduce. And he doesn't seem to notice anything off either. Without waiting for Koro-sensei's response, Tsuna headed to the window and pushed it open. Looking outside, he could only see students. A small group of students with bigger builds whom Tsuna would have been scared of when he was in middle school gathered at one end of the clearing in front of the schoolhouse, playing on their portable game devices. The boy who led the group was named Terasaka Ryoma if Tsuna remembered clearly (And he better remember clearly, a voice that resembled Reborn's echoed in Tsuna's head). A circle of girls was playing with a jump rope near the center, where there was more room. Tsuna could make out a couple heads bobbing up the mountain, returning from buying lunch. On the other end of the clearing, another group of boys hung out under a larger tree. They were simply talking, though one was sleeping. Akabane (The red-haired boy made a memorable impression on Tsuna the day before) was up in the tree, lying on a branch, completely relaxed. He's a lot like Kyouya, Tsuna thought a touch wistfully, thinking about how his friend-not-friend challenged everyone he interacted with, like how Akabane subtly did to Tsuna the day before.

"Something wrong, Tsuna-sensei?"

Tsuna nearly forgot that Koro-sensei never answered his question, but it didn't matter anymore. He shouldn't have expected any sort of answer from the first place. It didn't hurt to try, though. His Intuition still tugged at Tsuna, and it bothered him. A potential danger is near, it told him. And Tsuna's own thoughts finished with, near these precious children.

"...Nothing," Tsuna murmured quietly, but he was sure Koro-sensei heard anyways. He turned away from the window to face his target once more. "Didn't you want almond jelly?" he gently reminded.

Koro-sensei eyed Tsuna speculatively before saying, "Oh! That's right! Thank you for reminding me, Tsuna-sensei!" It was as if Tsuna's one-sided interrogation never happened at all. But that was fine. "By the way, your eyes are orange, did you know?"

A hand reflexively raised to his face, covering his Flame tempered eyes, but Koro-sensei had already disappeared in a blur. Slowly lowering his hand, Tsuna allowed his thoughts to drift again.

Shiota Nagisa.

That was the name of the boy with those sky blue eyes, wasn't it?

A small smile graced Tsuna's lips. Akabane wasn't the only one that reminded Tsuna of someone else. Shiota wasn't any good like him, but Tsuna was sure that even Reborn would agree that the boy had the same potential that Tsuna did.

Chapter Fin.

Omake

One...Two...Three...Four...Fi-

Koro-sensei walked towards the opposite end of the blackboard to point something out.

One...Two...Three...Four...Five...Six...Seve-

Koro-sensei stepped towards the desk of the student sitting in front.

One...Two...Three...Fo-

Koro-sensei stepped backward and turned to face the blackboard.

One...Two...Three…Four...Fi-

Koro-sensei had turned to face the class once more.

Dammit!

Tsuna let his head drop to hit his desk with an audible 'THUNK', earning the attention of everyone in the room.

"Tsuna-sensei? What's wrong?"

"It's nothing," Tsuna groaned.

"If you say so."

Koro-sensei continued to teach.

One...Two...Three...Four...Five…

Bucket: Whew, done. Here I was, whining to Yuki with 'Can I just make it 3000 words long this time?' but I ended up making it longer than the 3500 she set for me.

Yuki: Did anyone get the omake? Please review and tell me if you did.

Bucket: (Insert puppy dog eyes pleading for you guys to understand.)

Yuki: Because of the reviewers who asked to see the POV of the students, here it is! We hope that you like how it turned out.

Bucket: Because it's the students' POV, all the students are referred to by their first names (It was troublesome replacing Sugino with Tomohito). But then I realize it's more of a Nagisa's 3rd Person POV, but I personally think that's okay for these more general parts since he's the main-ish character of AK anyways. Welp, thanks for reading and waiting. (I almost typed reading and weeping without realizing.)

Yuki: Remember to review again! And HOPEFULLY, we won't take another year and eight months to update the next chapter.
