Hikari knew something was different this year at school before she left the apartment. Simply, because she got a phone call.

"Ari-chan, you're starting school today, right?", Hikari knew that voice anywhere.

"Izzy. What a lovely surprise, did you run out of angsty teenagers to harass?", her voice was way too casual as she said this. A bit like the way you would greet a friend at school.

"Not today unfortunately. It's soooooooo boring over here. But it sounds like you're going to be having some fun~ I'm so jealous", Hikari frowned ever so slightly. Izaya's version of fun didn't always line up with hers.

"Awesome. I'll tell you all about it later then", Hikari hung up and stuffed her phone in her pocket. This will probably be a pain, Hikari thought as she headed out the door.

"I'm off", Hikari said as she passed by her oldest brother. He simply nodded in return, not looking up from his breakfast.

They had been close once. Hikari used to tag along on Shizuo's jobs when school was out. Hikari even helped him fight. But Izaya had ruined everything, or at least that was Shizuo's standpoint. He was the one to beat Izaya within an inch of his life, and Hikari herself.

If Hikari hadn't been there to take most of the hits, her best friend would be dead. That had terrified her more than she would like to admit. It didn't help that she suffered from night terrors now. So for the past year Hikari and Shizuo have barely interacted. Hikari didn't hate her brother, but she couldn't stand to look at him. He almost-

It doesn't matter right now, Hikari pushed away all thoughts and left for school.

Something was definitely wrong with this school. Hikari trudged up the way to the classroom. It wasn't like it was a hard walk, but the distance the main building put between the E-Class must be traumatizing to the other students.

Hikari was never really bothered by this personally, but still wanted to beat up the bastard who came up with this. She really was a Heiwajima.

I wonder what Izaya meant. I hope I find out soon, or I'll go crazy trying to figure it out. Hikari sighed just as she reached the E classroom. There was a military helicopter stationed next to it.

Well, damn… Izaya really wasn't messing with me. Hikari walked inside without hesitation.

The rest of the class was already there and seated. Hikari sat down at her seat behind a girl with glasses and hair in two braids. The bell rang as soon as she sat down.

Military people filed in, four in count. And a… Yellow octopus? Wearing old man clothes? And an emoji like face? Hikari made a mental note to punch Izaya later.

"Nice to meet you. I'm the one who blew up the moon. I also plan to blow up the Earth next year. Seeing as I've become your homeroom teacher, I look forward to working with you", Hikari didn't even blink. Can't really blame her, one of Hikari closest friends doesn't have a head. Then why is it here? Did the government really think bringing someone who plans to destroy the world to a classroom safe?!

"I am Karasuma from the Ministry of Defense. First of all, I would like you to understand that what I am about to say is classified government information", Karasuma waited a moment before continuing. Hikari glanced at the rest of the class, they were dumbstruck.

"Now cutting straight to the point. I want you to kill this monster!", again the class was shocked, and again Hikari promised to punch Izaya.

"Er. What? So that guy is an alien who came to attack us?", Hikari immediately thought of Celty's irrational fear of aliens and police.

"How rude! I was born and raised on Earth, you know", the whatever- or I guess target- yelled indignantly.

"I'm afraid I can't speak the particulars, but what he told you is true. This creature, who damaged the moon, will also destroy the Earth next March. The world's leaders are the only ones who know about this-", wrong. "Before the world is plunged into panic… They are exerting considerable effort to kill him behind the scenes. In other words", Karasuma pulled out a green knife from his suit.

"An assassination. But at any rate, this guy is fast! Far from killing him, I'm having my eyebrows trimmed by him! Meticulously even! He is a super creature possessing enough power to transform the moon into a crescent. His maximum speed is Mach 20! In other words, if this guy was to seriously run away, we would be helpless until the day of our destruction", Mach 20! Seriously? You need at least Mach 23 to get into space… how did he get to the moon in the first place? Hikari frowned at the holes in their story. This is really gonna be a pain.

The target then went on to say that he didn't think they could kill him and how he would be their homeroom teacher for the rest of the year, or possibly the class's lives. Everyone seemed to be ready to explode with questions when Karasuma said the reward would be ten billion yen.

"That's the long and short of it. Now let's spend the rest of the year in a meaningful fashion", Hikari smiled slightly. Oh yeah. This'll be fun.

"-And end with, 'It was tentacles'", the classroom as a whole groaned at the target's assignment. Hikari just leaned back in her chair and started dozing, she had no intention of doing this immediately. Going home wasn't a very good motivation. All that awaited there was awkwardness and homework. So Hikari wasn't paying attention until the explosion actually happened.

BOOM!

Hikari stood up so fast, the chair got knocked over. She ran over to where the blue haired boy, Nagisa, had fallen.

"Alright! We did it! That ten billion yen is ours!", Hikari had to stop herself from turning and punching those bastards in the face. Those stupid- wait, is this membrane? Hikari pulled it off and helped the perfectly fine Nagisa up. Everyone looked shocked he was alive.

Then the voice of the target made everyone look up as the yellow fiend started explaining how he sheds his skin once a month. He was pissed. But when he brought all the nameplates of their families, Hikari flipped.

There was her brother, Kasuka's plate. I'll… I'll kill him! Hikari stalked back to her seat, barely containing bloodlust. I need to calm down. She almost missed the target's appointed name. Koro-sensei.

Hikari was the last to leave.

"Ah, Heiwajima-san. You seem to be the last one out. Have a nice weekend!", Koro-sensei took the finished assignment and turned around. Hikari started for the doorway when she paused, and turned around silently. Hikari's pocket knife slid into her hand from its hiding spot in her sleeve. She had coated it slightly in anti-sensei clear liquid. Now she could test her idea.

Koro-sensei noticed it at the last moment, but didn't dodge. So he does think it's a normal knife. Hikari smirked slightly as the knife impeded itself in the wall, a portion of Koro-sensei's tentacle attached.

There was a deafening silence for a few seconds before Koro-sensei spoke.

"That was a very nice assassination, Heiwajima-san, but not very creative", he pulled the knife out the wall using a cloth. Koro-sensei flipped it close and handed it back to Hikari.

"And carrying real arsenal on campus is not allowed", Hikari laughed slightly.

"I wasn't trying to kill you, just testing my theory and I don't really care what the rules are", Koro-sensei's face turned purple with disapproval. But Hikari made for the doorway again, before pausing yet again.

"Also, if you threaten my family again. I won't just kill you, I'll drag you down into Hell", Hikari left before he said anything.

Up on the hill, Koro-sensei frowned. Or well, his equivalent of frowning.

"Heiwajima, Hikari", Koro-sensei sighed. "Seems she's going to need more polishing than I first thought"

Hikari really hated weekends. They were so awkward, having to pass by Shizuo all the time and so boring, since Izaya wasn't here. Celty and Shinra had weird schedules too. Everybody was always busy.

Thankfully, this weekend Hikari got to spend a lot of time with her young friend, Akane. It was then that Hikari finally noticed she got along with the weirdest people, since she was on friendly terms with the high members of the Awakusu Group and the Asuki Group. Maybe I need to socialize with normal people more if I'm spending my weekends with the yakuza. Hikari sweatdropped at her thoughts.

At school, everyone was getting less depressed with arrival of Koro-sensei. Hikari was glad, though didn't make any friends. Izaya kept calling her off-putting, was that true? Hikari shook off those thoughts and sweatdropped at the scene in front of her.

Apparently, Koro-sensei ripped up all the flowers the class had grown so he had hung himself from a tree so everyone could try -and fail- to hit him. Hikari realised she was the very first to actually hit him earlier. That made her a bit happy.

"Is that so? That means you're Karasuma-sensei now", Hikari turned to see Karasuma and Kayono talking. Oh, he's going to be a teacher now? That makes things easier, Koro-sensei is terrible with PE.

Things quickly got out of hand as Koro-sensei snapped the branch and started panicking. Hikari sweatdropped again when he was freaking out. Isn't he supposed to destroy the world?

Hikari facepalmed when he finally got away and gave them more homework. How petty! She went back into class, a rare smile on her face.

Hikari walked into the classroom just as the bell rang. She had skipped PE again, so this was the first time she saw the new student. Her first thought was, of course- Great. Another one. Hikari recognized the look. Laid back, sarcastic, infuriating, manipulating and a bit of an ass. Please don't be like Izaya, please don't be like Izaya, please don't-

"Who are you?", the new kid asked her as soon as Hikari sat down. His seat was next to her in the back row. Hikari noted his bright red hair and cunning smile.

"Hikari. I skipped PE", his smirk widened and was probably going to say something else when Koro-sensei walked in. If Hikari hated one thing about that type of guy, is the bravado they put up. It took far too long and far too much work to see past it. Hikari would know, Izaya finally dropped it when she came- Don't think about it.

Near the end of the test the new kid, or as Hikari had learned Karma, had tricked Koro-sensei. Hikari tried not to laugh at that. In the days to come, as a series of failed attempts at assassinating Koro-sensei came from Karma. Hikari noticed on the last day of the week he was acting different. More laid back and less so full of bloodlust. Or well, the unhealthy kind. Good for him.

"Heiwajima-san", Hikari was again the last to leave, she even got to the yard outside. She turned towards Koro-sensei nonchalantly.

"Yeah?", Karasuma-sensei came out too.

"You haven't been to a single PE class, why is that?", Koro-sensei asked Hikari. She frowned, I was hoping they would leave it alone. She then smirked slightly.

"It's too easy and boring", Karasuma-sensei was now paying much more attention to the conversation.

"Oh, even so, you can't kill me with whatever talents you possess now", Koro-sensei taunted. Hikari shrugged, verbal attacks are usually useless against me. I grew up in Izaya's shadow, you have a very little chance of getting to me that way.

"I know. That's why I practice on my own farther off. Better to sharpen my own blade by myself than have it dulled with others, right?", Hikari was now full blown smirking. She was egging Koro-sensei on, since he had failed trying to disturb her. This was when Karasuma-sensei intervened.

"If you believe you're so much better than the rest of the class", he took off his coat and pulled out a anti-sensei knife. "Do what they couldn't"

Karasuma-sensei tossed the knife to Hikari. The smirk left her face, now a serious look on. Hikari charged him outright, but feinted to the left just as he was guarding. Taking this chance, Hikari used her free right hand(btw she's left-handed) to hit a pressure point on his right arm.

Karasuma-sensei recoiled instantly, before ignoring his paralyzed arm and tried to disarm her while Hikari was open. She moved faster, ducking under his arm and slashed his chest with the knife, before kicking him in another point on his left leg. Karasuma-sensei tumbled down. Hikari stepped back, smirking at her victory. There was silence for a full minute, before Karasuma-sensei stood back up, perfectly fine.

Hikari whistled softly.

"Amazing. Those pressure points usually keep people down for three minutes", Karasuma-sensei looked at her in shock. He clearly didn't expect her to hit him. Besides that, he may not be as strong as Shizuo, but the fight would have lasted much longer if Karasuma-sensei gave it his all from the get go.

"Where did you learn to fight like that?", Karasuma-sensei questioned her. Hikari turned around, starting to walk home.

"You probably wouldn't like the answer"
