AN: I liked the anime series, and I would like to read the light novels, but as of publishing there is no english translation available. Apparently there was a fan translation up to volume 6, but that was taken down before I could read it past volume 1. Just checked. Apparently there are 17 light novels in all, with no Enlish translation in sight. Thus, here we go: Continuing off from where the anime ended, with no clue where the light novels lead.

Unusually, Souji was having a very ordinary day. This might sound like something of an oxymoron, but only without context. It was unusual because every day for the last few months, Souji had been made to fight Elemerians to protect the earth's attributes from falling into the hands of evil.

Until that ordinary day, his daily schedule would have been something like this:

In the morning, he would be awoken by his longtime friend, Aika Tsube, and go to school together with her like any stereotypical pair of childhood friends. At some point during the day aliens would attempt to invade somewhere on earth, and one or more members of the Twintail Club would be dispatched to defeat them via their space jump catapult, which was effectively a teleporter. With that done, they would return to school, and go about the rest of their day indistinguishable from any ordinary student.

But that day, and the day before, there had been no invaders. The Elemerians, at least for the moment, had left the world and gone to deal with other problems elsewhere. It would have been a relief, if they weren't already so used to the attacks as part of their routine. Souji could tell that Aika in particular was feeling quite antsy. During classes she kept checking her wrist and glaring out the window suspiciously, a behaviour which was noticed by their other classmates. She already had a reputation for being pretty short tempered, so they were all inclined to leave her alone.

That was probably for the best. Without any gildy's around she didn't have as many ways to relieve her pent up aggression. I might need to do something about that before someone gets hurt…

And by someone he of course meant Twoearle. She was a human from another world, or at least something very similar to a human, that had a bad habit of teasing Aika and was thus, consistently on the receiving end of vicious beatdowns. He'd never known Aika to show much restraint in the past, and overtime he had noticed her using more and more dangerous techniques, so these days there was a pretty serious risk their friend from another world wouldn't survive a bad encounter. So far it seemed like Twoearle had noticed Aika's shortened fuse as well, and had wisely left her alone. At least so far, though he kinda doubted she could keep her mouth shut indefinitely. Despite being a mad scientist super genius, Twoearle was something of an idiot.

"Um…Twoearle?" You might be forgiven for mistaking the speaker with a particularly short middle schooler that somehow snuck into Yougetsu Academy. She was in fact a senior at the school and her name was Shindo Erina. The first thing anyone might notice about her was just how small she was, but the first thing Souji ever noticed about her was her beautiful blonde twintails that stretched down almost to her knees. Oh, what lovely twintails they are…

Erina continued in the absence of interruption. "I'm sure I'm not the only one who's been wondering, but… we haven't been attacked in a while, so… What are we supposed to do now?"

If someone struggled to believe Erina was a highschooler because she looked too young, they'd struggle to believe Twoearel was a highschooler because she looked far too mature. Souji thought her boobs were ridiculous. Her silver grey hair didn't help either. Honestly, he didn't even know her real age. She was from another world, and it's not like she brought valid ID or anything. Either way, she was somehow allowed to attend the same school as everyone else, but Souji was pretty sure that was because she could hypnotize people.

"Yes, it's mostly a good thing." Twoearle agreed. "With the extra breathing room I can start working on a few projects I've had in mind for a while now. Which is actually what I wanted to talk to you about today. I have a proposal."

"A proposal?" Aika sounded suspicious. "Like what?"

"Oh, you know. Traditional service, with a white dress and a small number of people invited. I was thinking church, but-"
The sound of a chair loudly scraping against the floor interrupted her, as Aika stood up suddenly.

"Of course you were going to be invited!" Twoearle started sweating, as Aika stomped around the table angrily. "Obviously, Souji would need his best man there and I can get you a great discount on tuxedo's from-"

The force of the blow to her face rattled the shelves, and Souji winced subconsciously. He felt that thump in his chest from across the room, and he wasn't even the one hit!

"Hmf." Aika kicked Twoearle one more time while she was down, before taking her seat again. "Are you just going to keep wasting our time?"

Hey, I don't think you can really say that when you're the one who knocked her out...

A few minutes later Twoearle continued, wincing as she pressed a fresh ice pack to her face. "As I was saying before I was violently interrupted-"

"I can interrupt you again in a minute!" Aika warned.

"Aika, just let her speak." Souji tried to keep his tone gentle, but exasperation must have crept in because she still gave him an annoyed look. At least she didn't add anything else. Then he turned back to Twoearle. "You should know better than to provoke Aika." He warned her.

"Eh-heh-heh." She laughed nervously, before trying again. "We've done enough damage to Ultimagil that for now they're going to go after some softer targets, rethink their strategy, and then come at us again later."

"That means we're gonna need to get a lot stronger, right?" Aika pondered. "Or maybe fortify, somehow…"

"While we definitely need to do both of those things if possible, those are only temporary solutions to our problem." Twoearle's voice took on lecturing tone. "There's an infinite number of worlds out there, on any one of which the Elemerian's could potentially find the strength to crush us here. Not to mention, every attack they make here has the potential of succeeding and undoing all our successes."

She was right. They'd had a large number of very close fought battles so far, any one of which could have ended in complete disaster. To keep the earth safe, the Twintail Warriors had to win every time, while the invaders only had to get lucky once.

"Are you saying we need to go on the offense?" Aikia frowned. "How? Do they have a homeworld?"

"No, not that I know of." Twoearle shook her head. "Plus attacking it with just the four of us would probably be completely hopeless."

Souji nodded in agreement. Defeating just one officer class was exhausting, let alone the even more adjutant's like Arachnegildy. He couldn't even imagine fighting a world of them and winning.

"Instead, I'm thinking we need to start recruiting." Twoearle reached into her generous cleavage, and took out what looked like an ordinary set of car keys attached to a fluffy pink ball. "I still have the spaceship I used to come here."

"Are you talking about a universe of twintail warriors?!" Souji stood up in excitement, pushing his chair out as he did.

At the same time Erina excitedly added in her small voice. "Like a superhero crossover?"

"Yeah, pretty much exactly."

The voice of skepticism spoke again. "Why don't we just recruit here on earth?" Come on, Aika! Can't you see how cool this is?! Souji thought it was just like Aika to look for the boring side of everything.

"We don't have any more pure Twintail attribute." Twoearle pointed out. "I can't make more tailsuits without it."

"How will going to other worlds fix that problem?" Erina's voice became uncertain. "We're not going to steal attributes from them, are we?" Clear disapproval crept into her tone.

"No, no, no!" Twoearle quickly shook her head. "Absolutely not. I want to fight the Ultimaguil to stop other worlds from suffering the same fate mine did. Becoming what they are would defeat the purpose. My idea is Soji will do for another world, what I did for this world."

"I don't follow." Aika's brows came together in confusion.

"For a while now, the Elemerians have been using a seeding strategy, where they pretend to leak a tailsuit to a selected warrior from that world's local population, and then lose a number of battles to that warrior so as to make them appear a hero. This will inspire people all across the world to love twintails as well, so that when the Elemerians then crush them with an officer class guildy and a vast swarm of lesser Ultiroids, they can then harvest a greater amount of precious twintail attribute."

Ah, just the thought of it made Souji angry. Someone with a sincere love of twintails being puppeted in such a way, and then discarded with everything they treasured stolen from them. It was the fate that awaited him, or Aika, or whoever else the aliens chose to be their patsy if Twoearle hadn't arrived ahead of them.

It was easy to imagine his childhood friend being defeated like that, and he found himself growing upset. Because he'd known her for so long and been exposed to them every day, he often forgot just how beautiful her straight black twintails were. She put so much work in to caring for them! They might have even stolen her karate girl attribute! Pretty sure that's a thing. Who would she be without even that? Really just a grumpy, rude, manly girl. With no boobs at all, either. Who eats way too much.

Geeze, without the motivation to exercise, she'd be as fat as American in just a few months. It would just be too sad.

She noticed him staring at her, and regarded Soji suspiciously. "I know you're thinking something bad about me."

He was reminded just how well she knew him, and felt a prickle of sweat on the back of his neck. Her punches were getting really hard lately, she was forgetting how to hold back.

Souji turned back to Twoearle quickly. "If we interrupt their plans on other worlds by saving those Twintail warriors, we can save those worlds, stop them getting more Elemera, and expand our numbers all at the same time!"

"That sounds great. Couldn't we have done this sooner?" Erina asked, a hint of excitement entering her voice.

"The problem is a journey to another world could take more than a month." Twoearle shrugged. "We just never had the time before. Now we have breathing room, and some spare Twintail Warriors so we can protect the earth while one of us makes the journey. Once we get to our destination, I can build a gateway so we can reconnect with the team back here on Earth instantly. It will add the new twintail to our forces to protect our world, while we add their world to the places we can defend from Elemerians. Which is probably a good deal for them, too."

"And it would be a great chance to see other great twintails!" Souji was pumped. "I'm in, this sounds great!"

"Okay, hold on one second!" Aika stood up, and they all looked to her. She kept her gaze locked on Twoearle and stated flatly. "I'm gonna assume that you need to pilot the spaceship?"

"I certainly can't imagine a barbarian like you learning literal rocket science anytime soon, so yes." She gave a superior smirk. Damn it, Twirl, stop. If Aika gets you in another armlock, I won't be able to pull her off you!

"And you're going to need one of us to go with you, right?" Aika crossed her arms and narrowed her eyes at Twoearle. "Two of us will need to stay here in case the Elemerians come back, and one of us will go with you to keep you safe and help the other world's tail warrior, right?"

"Exactly." Twoearle grinned and her eyes kept glancing towards Souji but stayed facing Aika. "And I'm sure your next question will be who goes and who stays, right?"

"Somehow I have a hunch who you think that should be."

"Eh-he-heh. Whaaaat? I have no idea what you mean, but I'm sure we can talk this through and come to the most reasonable outcome." Twoearle looked to the sophomore. "Erina, given your family situation, and the enormous pressure placed on you to succeed socially, do you think you'll be able to convince your mother to let you leave under dubious reasons for a month or more?"

"Oh, definitely not." She shook her head vigorously. "Just asking might get me in trouble."

"Mmhm. What a shame." Twoearle said without a hint of sincerity. "And Aika, what about you? Don't you have a strict regime of karate to keep up with? And like, a ton of raw meat to eat or something?"

Aika cracked her knuckles threateningly.

"B-b-but, seriously." Twoearle continued quickly. "What about your parents? And would you really be able to convince your grandfather to let you go for a month or more?"

Honestly, Aika's parents weren't that strict. Her grandfather would want her to continue training, obviously, but he trusted her enough to keep up with it on her own.

"For argument's sake, let's say I can't." Skepticism oozed off every word. "What would that mean?"

"Well, I'm sure Soji would have no trouble at all convincing his mother to let him go for the summer holidays. And I'll be sure to help him get his summer homework done." Drool started to creep down from the corner of her mouth. "Eh-heh-heh. And I can teach him to drive stick."

"You stupid horny-"

"It sounds great to me!" Souji smiled at Aika brightly. "My mom will definitely be a lot easier to convince than yours." Images of beautiful, exotic, alien twintails ran through his mind on a loop and he clenched his fists with excitement. "I'm super pumped."

"So that's settled, then!" Twoearle rubbed her hands together eagerly. "Aika and Erina will stay here on earth, while Souji and I go for a month long love in~!"

"Except that's not what's going to happen!" Aika raised her voice in anger, a large vein twitching on the side of her head.

"Why not?" Souji asked, disappointment creeping into his voice.

"There's one thing you haven't considered, Twoearle." Aika growled. "Two things, actually."

"And, uh, what are those?" Twoearle swallowed nervously, backing away a step. Souji could see her hand reaching for a remote shaped bulge in her pocket, probably to summon another anti-Aika bot, not that it would help her much...

"First of all!" Aika raised her index finger. "If you think for a second that I'd let you spend a month alone in space with Souji, you've got another thing coming. Secondly, and more importantly, Souji can't leave Earth. He's our strongest warrior."

That brought everyone's excitement up short, and Souji frowned as he considered her argument.

"If Souji leaves earth, and another Elemerian as strong as Arachnegildy shows up, there'd be nothing I or Erina could do to stop them." Her lips twitched downward with annoyance at the admission. "Him leaving is too big of a risk. Honestly, it seems risky for even one of us to leave."

A look of consideration came over Twoearle's face, followed by one of disappointment that Souji matched. "Oh."

Yeah. 'Oh.'

He sat down heavily, and sighed, running a hand through his hair. "You're right, Aika."

She saw the look on my face, and smiled apologetically. "We can't risk everything by having you leave, Soji. I'm sorry."

"Then who goes with Twoearle?" Erina asked, looking between us.

"It's gonna have to be me." Aika shook her head sadly, and looked back to Twoearle. "Unless you have a way to make us a lot stronger very suddenly?"

The shake of Twoearle's head was slow and dejected. "Nooooo…" She groaned, sinking into her chair and putting her head the crook of her elbow while banging her fist against the table. "Oh, nooooooo. Not a month alone with the barbarian… Space travel is soooooo boring!"

Oof. That was a new worry. Would Twoearle even survive a month alone with Aika?

Souji looked at his childhood friend, who was tapping a finger against one arm in agitation while a thick vein throbbed on her head.

Meanwhile, on another world much like Earth, a camera looked down from far above as a young girl with Twintails stepped out of the passenger seat of an expensive black car, just one block away from her school. She aggressively ignored the glares people gave her, while blissfully unaware of the sinister eyes that watched her every move.

She was identical to a human in almost every way, with only two major differences: The long thin tail that hung from her waist down to her ankles, and the pair of cat ears sitting atop her head. Neither of them were fake. They were organic and completely natural on this world. Every single person she passed on the street shared the same traits. That wasn't what drew their ire.

You see, the people of Nyapon were incredibly conservative in their views on hair. Everyone there wore it short, or in a traditional long ponytail. Anything more than that was excessive and indecent in their minds, and anyone who violated this cultural taboo would inevitably draw the ire of their peers.

In aggressive defiance of this view, this fourteen year old girl with her nose turned up in the air as though she smelled something bad, sported a pair of twintails that had been heavily curled into a magnificent set of pink drilltails.

"How indecent!" A passing mother spat, covering her young son's eyes, lest he be corrupted. "Don't look, Love."

"Hmph!" The fourteen year old girl brushed the right drill with her hand, shaking her head so as to set both magnificent tails swaying.

"Oh, my lord!" A grandmothers' eyes rolled up in her head, and she fainted from shock.

"Plebians!" The girl rolled her eyes as she called over her shoulder, before hurrying along to school.

"...She's perfect." A sinister voice hissed eagerly, while it watched all this happen through a screen. "Oh, I love snooty, rich, bitchy princesses." A clawed hand reached out to caress the monitor, as a pair of mandibles clicked together eagerly. "And I especially love seeing them fall."

Her name was Nakatomi Izaberra, or Isabella Nakatomi if you happen to be Ameowican, or Catnadian. Soon she would be known by another name.

Tail Pink.
