Skull was an exciteable person, but he got over the shock of having Tsuna under his wing very quickly and got down to business.

Skull couldn't teach anything combat-related to Tsuna...besides, he was learning just fine under Fon. He didn't have any 'marketable' skills as a Pro Hero since he preferred stunt work and he only got his license because it opened up a lot more work for him. He wasn't particularly brave, smart or good at normal hero work.

What he could do was act, and he knew the ins and outs of most machines he came across so long as they weren't too advanced and had an engine. He knew how to put on a mask and pretend everything was fine even when his own life was going to hell, and how to fake it like a pro. More importantly he was an avid fan of parkour and insane stunts, which was something Tsuna was rather happy with.

Sure, Skull wasn't the most 'marketable' hero, but he suited Tsuna far better than someone like his grandfather would have. Tsuna would rather be the quiet hero that comes in when the chips were down and helped to turn things around rather than be in the spotlight all the time like All Might.

He could leave that sort of thing to Deku.

A few days in...

Tsuna should have been in a good mood. Training with Skull was awesome, and he was quickly falling in love with driving motorcycles. Sure, having to act was rather annoying, but it was doable if only because he could put to use a lot of the skills he had picked up by necessity to hide what he was really feeling towards the idiots he had to deal with on a daily basis.

Skull hid his true self behind the guise of a braggart who wanted all the attention on him.

Tsuna chose to go a different route. While he was perfectly friendly to others, he always kept a disinterested and apathetic persona on the outside. Mostly to hide his rather large sarcastic streak, since he pretty much hated everyone and only a select few got to see his "nice" side in the first place.

Wearing his headphones helped a lot...it meant he could ignore people under the guise of listening to music, while in reality he was listening to everything going on around him for roughly a hundred and fifty feet.

The thing that pissed him off the most was the fact Iemitsu would not take a freaking hint and go away. He apparently believed the fact that Tsuna was studying to become a Pro Hero and had been outed as All Might's grandson was an excuse to harass his "son" into joining the group he was part of after graduation.

Honestly, the idea of working with that man made Tsuna's skin absolutely crawl. It was as if the past decade didn't actually matter now that Tsuna had some "worth" in the eyes of society and his "father" was simply trying to snatch him up first to show off like a prized bird or something.

Tsuna had not been joking about the restraining order. After the third time he "accidentally" ran into his genetic donor Skull took him to his personal lawyer to have the order filed. It was done in less than two days, since it was blatantly obvious Iemitsu was only bothering his son because he had become "famous".

The fact that All Might wanted to have a "word" with the man in private regarding the fact that he had sealed his grandson and basically abandoned his daughter to act as a single parent was even more damning.

That being said, Tsuna was enjoying every second he had training with Skull.

So you could imagine his confusion when Skull presented him with an old guitar of all things. Not an electric one, but one made of wood that had seen a few users and would-be musicians over the years.

"What's this?"

"Your always listening to your tunes, or pretending to and everyone needs a hobby that lets them relax and unwind. So why not try to make your own music?" said Skull sensibly. "I mean I usually watch old movies, the cheesier the better."

"So that's why you have such a massive old-school Godzilla doll in your trailer."

"Gojira is the King, thank you very much. Not even that ass Reborn can top him. But I figured it would be an interesting project you can play around with during your downtime, since you mentioned you were already really good at playing with music programs on the computer."

"That was out of necessity, and it helped to bond with Shōichi. I suppose it couldn't hurt though..." mused Tsuna.

Later that night, when he took out the guitar Skull had given him and began to jam on it, he found himself lost in the music. It had a strange calming effect on him.

"So we're going to Hosu?" asked Tsuna.

"The guy in charge of the 'public' hero groups that do minor police work wants to see what we can do to raise moral after the Hero Killer took Ingenium out."

Tsuna snorted.

"Doesn't surprise me. People hand out titles like 'hero' like candy these days. It used to actually mean something before quirks became the norm. Now people think that their quirks are all they'll ever need without having to actually work for it, and rarely bother to reach any real heights like grandpa."

Skull was silent. He might be a Pro Hero, but in reality he was anything but. He privately agreed with Tsuna's disdain-filled comment.

"What would you rather be? I mean you are on the Pro Hero track like your grandpa."

Tsuna's eyes gleamed.

"I don't want to be known as a 'hero'. That title is thrown about far too casually these days and is more of a job description. If I have to make a living as a 'hero', then I don't want to settle for 'good enough'. I want to be a legend famous enough that people will remember me long after I'm dead and anyone who would be able to say they knew me personally is long gone too," said Tsuna.

Skull blinked, before a wide grin filled his face.

"Now that's the proper attitude to have! If you're going to be a hero, then be one that everyone remembers even when you're no longer around to remind them that you exist! Everyone is far too happy with the way things are and never challenge themselves anymore!" said Skull with approval. "I mean hell, who's going to say they remember who All Might was like a hundred years from now? He's famous now, but once he's gone and everyone who remembered him are dead and buried..."

"Exactly! What happened to the days of old when actual legends were made? Stories that inspired you and made you believe in things greater than you, like Joan of Arc, Alexander the Great, or Herakles?"

"Or Godzilla?" said Skull impishly.

Tsuna nodded in full agreement, grinning. He looked far more animated on the subject than Skull had seen him for the past three days.

"So is it true you hijacked the USJ to play your music and accidentally inspired the rest of the baby heroes to fight back?"

"Want to hear the CD? It has the song on it," said Tsuna.

"Sure!" said Skull grinning.

The two were happily jamming on the way to the city. Skull had a very similar taste in music and they were debating on different songs and genres the entire ride.

You could imagine their horrified shock at seeing the city under attack.

Tsuna looked at the text he got from Deku...he had the worst feeling his friend had found the Hero Killer, or had gone searching for Iida. He had the feeling it was more the latter, with the former being an unhappy coincidence.

"Skull, do you want to help the other pro heroes, or come with me to help a friend? I have a horrible feeling Deku found the hero killer."

"I'm not much of a fighter though," said Skull, shivering.

"I don't expect you to. But I bet you know basic first aid and know how to keep your head down and get those incapacitated out of the line of fire so that others don't have to worry about accidentally hitting any ally," said Tsuna calmly.

Skull perked up.

"Now that is something I can do!" said Skull grinning. "Count me in!"

"Besides, this way if anything happens we can claim we were backing you up," said Tsuna sheepishly.

Skull snickered.

The two of them made their way to the alley Deku had texted them about, and found things were somewhat dire. No only was Deku paralyzed, but so were Iida and Todoroki and the pro hero that the Hero Killer had been targetting before Iida showed up.

Skull was terrified, but he remembered what Tsuna...or rather Flameheart said. He wasn't expecting the stuntman to fight. He wanted the purple haired hero to get the invalids out so that they wouldn't get caught in the crossfire.

"Tsuna? What are you doing here? It thought you were in your hometown?"

"Skull was asked to do a TV promo to try and raise moral after this guy showed up and took out Ingenium. We came in time for the Noumu to show up," said Tsuna. "That being said...I can kinda understand where the Hero Killer is coming from."

Dead silence.

"Tsuna, you didn't hit your head recently, did you?" asked Todoroki.

Tsuna rolled his eyes.

"Every time this guy shows up, the heroes finally get up off their asses and actually try to better themselves for as long as the reminder is present, rather than sit on their asses all day and rest on their laurels. Crime takes a massive drop across the board and suddenly they're reminded that there are villains all too happy to take them out. The title 'hero' is used far too often these days to the point it's completely lost it's actual meaning."

The 'heroes' all stared at him in shock...but deep inside, something stirred in junior heroes hearts. Especially Deku.

"That being said, I don't appreciate the fact that villains go out of their way to target innocent people who have nothing to do with their attempts to stir up anarchy and chaos, save for being in the wrong place at the wrong time. There was absolutely no point of letting all those Noumu go to attack people," said Tsuna flatly.

"...I have absolutely no idea what you're talking about. I didn't let any of these...Noumu...loose," said the Hero Killer calmly. "And I only target heroes."

"Considering you were in another area of Japan entirely when the first one showed up, I believe you," admitted Tsuna. "That being said, I'm not going to let you kill anyone here. If anyone gets to pound Deku's face in, it's going to be me in training."

"Hey!" shouted Deku.

"Oh come on, you don't practice your martial arts skills nearly enough and you're lucky Hibari doesn't feel like making your hero name 'chew toy'. You really need to learn how to fight without using your quirk, because your lack of control with it is only going to bite you in the ass," deadpanned Tsuna. Deku pouted.

"Heh...HAHAHAHAHA! I like you brat! You have good eyes on you! You have a better idea of what a hero should be, compared to these wet behind the ears brats!" cackled the Hero Killer.

"I should hope so. After all, I realized a long time ago that weakness only remains that way if you let it. Nothing motivates someone better than the desire to spite those that claim you're never going to amount to anything because society thinks you're worthless without a quirk," said Tsuna, his smile all teeth. "That being said, I refuse to hide behind my grandpa's name when I could be going out and making one of my own. Forget pro hero, I want to be a legend no one forgets and reminds people what the term hero actually means."

Tsuna punched his right fist into his left had with a gleam in his eyes. It was clear he meant every word.

"Oh? And which pathetic hero is your grandfather supposed to be?" asked the Hero Killer, as calm as could be.

Tsuna's grin was wicked.

"All Might. Deku might be his protege, but I'm the grandson he never knew about until recently," he replied.

The wicked gleam in the Hero Killer's eyes grew bigger.

"That being said... Homura, you cover for Skull while I play with this guy okay?"

Tsuna's flame clone made an "Ok" sign with his hand, and went to cover Deku and the others while Skull got the invalids out of the way.

"Not going to fight with your quirk?"

"Why would I bother fighting with Homura when he can be more useful acting as a protective measure against you?" said Tsuna cheekily. "After all... I don't need him to fight."

That was the only warning Tsuna gave...before he moved.

Deku had to stare in disbelief. He had never seen Tsuna move so fast. It took him a moment to realize he was able to move his body again. Was there a time limit to the Hero Killer's quirk?

There was the sound of something heavy crashing into the Hero Killer before it fell to the ground and made a decent crater in the ground, and Tsuna became so much faster.

"What the hell? What did Tsuna just remove from his arm?" asked Todoroki in disbelief.

"...I think those are weights, but why would he be wearing them?" said Iida.

"Can you think of a better way to do strength training without having to hit the gym all the time?" Tsuna cheerfully called out.

There was a reason he had meshed with Kyouya so quickly, and it wasn't because he knew how to attack the older boy's feline features in a way that made him a puddle of goo.

Tsuna was just as much a battle maniac as Kyouya, he just didn't bother with attacking people at random unless he found a strong opponent he could really let loose with.

The wild grin on his face said far too much about how much he enjoyed the thrill of battle, and how his blood was absolutely pumping from the cat and mouse game he was playing with the Hero Killer.

"Keh... How... are you so strong?" asked the Hero Killer.

Everyone looked to Tsuna for an answer.

"It's in the blood, I guess," said Tsuna flippantly.

"Really?" said Iida.

"Gods no! I took that little voice everyone has in the back of their head that tells you to be tactful and understanding to idiots and sheep...and I shot it. I shot it in the god's-damned face until that bastard died and then used pure spite to motivate me into becoming stronger so that when I got a real chance, I could show them how little I cared about their opinions. After all, if there's one thing I learned, it's that tigers should not concern themselves with the opinion of sheep," said Tsuna flatly.

Complete silence...then the Hero Killer started laughing, long and hard and with an unhinged quality.

"That is how a proper hero should be!" he said with glee and no little appreciation.

"...Isn't that an indirect quote from SAO Abridged?" asked Deku.

"Let's just say I sympathize rather strongly with that version of Kirito than I did the original," said Tsuna.

"Are you going to flip out and start randomly killing things the same way he did whenever that one NPC was mentioned?" asked Deku, almost joking.

"That depends Sachi... are you going to let your lag allow you to bring the group down?" said Tsuna smirking. "Just remember not to set the NPC's to autoloot, otherwise we'll all be sprinting to our deaths a record speed."

"You jerk! I am not Sachi!" said Deku scowling.

"I am completely lost," said Todoroki. Iida nodded. Skull...looked like he was having trouble not laughing as he caught most of the reference.
