*Yuna POV*

Just this one time I was happy that Yuuki didn't appear. Yesterday, after went to the ministry, I accepted their offer to re-joining the class, of course they also accepted some conditions that I gave them. They finally explained the whole thing and the mission that they mean was, assassination mission. Thank God, I was able to control my emotion so Yuuki or other didn't show up.

I was screwed! But, I can't take back what have I said before. There's no turning back.

The whole class had given the same mission and already began since the first day of their first semester. Who is the target? My teacher, who is not an ordinary one. Well, he was octopus like creature with super crazy abilities. He could move at 20 mach speed! Yeah, 20 mach speed! It was like 23.040 kilometers per hour! What the f***!? With that super freaking speed he can even cover the whole circumference of earth along the equator in about 1 hour and 44 minutes!

A few months ago, 70% portions of the moon had exploded and guess what behind it? Yes, it was my teacher. And he threatened will do the same to earth next March if we don't kill him. Apparently, this whole mission and the creature existence are top secret information which only a few state officials know about.

But, isn't this a little bit nonsense? A middle schooler got a responsibility to kill a superhuman and dangerous creature? Should the government assemble a bunch of superheroes like Avengers or Justice League or something like that?

Oh well, the point is...the government already tried a thousand – no maybe a billion ways to kill him but not a single one success. Until they find a new way, they forced to agree to the creature's circumstance which is to be our teacher. With a guarantee he won't do any harm to the students. The reason why he chose this school is remain unknown though. I want ask another question but I was silenced after they spoke about the grand prize if we success.

We will be given 10 million yen! 10 freaking million yen, baby! Oh...that's more than enough to answer all of my unspoken questions. Even this nonsense becomes a reasonable one. I could use that money for finding the best psychologist for Yuuki, and the rest of the money, I'll leave it for Yuuki. But firstly, I would like to know if ministry special weapons, which are rubber knife and bb pill, really effective on him.

"So, you're the new student." I was busy thinking about how I should try this weapon, until I didn't realized there are another person in my way. He was a tall man with a spiky black hair and piercing dark eyes. He wore a professional black business suit with a white shirt and a black tie. I observed him more closely and I was pretty sure he is one of the ministry officers that had a responsibility in the mission, judging from his well built body.

"Uh...yeah. Not exactly new, though." I shrugged nonchalantly since I thought this man, whoever he is, already know about me.

He nodded. "I know. I've read your data. I'm Karasuma Tadaomi, and I'm in charge as P.E teacher in here."

"Oh. Right...some kind of cover for you for being here, I assume?" I blattered out. Silly, of course he will need a cover, duh. He nodded once again. "I'll escort you to your classroom and you will soon begin your mission. My coworkers had given you the explanation, hadn't they?"

"Yes, sir – Ah, I mean, sensei."

"Good. This way." He said and turned around, and I followed soon after. As we walk to the class, he began explain a few additional details. I was dozed off a little and didn't hear what he had explained. I just bored in this crappy explanation s***. The only thing that I got is there is another professional in this class, who act as an English Teacher. Her name is Irina Jelavic. Yup, I'm positive she was the blonde teacher that I saw yesterday. Apparently, she was a hitwoman hired by government in order, of course, to kill the octopus.

Well, well, I found a place full of crazy a** people. I grinned, Yuuki would be freaked out if she found out about this. Well, IF she found out, right? Until I was sure we could fit in here, I couldn't tell Yuuki, or else she will ran away. And everything about finding new friends who could we rely will be crumbled down.

We finally reached the classroom. And Karasuma-sensei opened the door. I was a little bit surprised after I saw the octopus creature. Sure I've seen him in the photo, but...now right in front of me is a real one! The octopus was about three meter tall and possessed a large bulbous head with a large smile and a small beady eyes. He wore a black academic dress with a small academic cap with a yellow tassel and a large black tie with a yellow cresent-shaped moon on it. He...he was kind of...

'Cute!'

Oh, crap! Not now!

'Alice, back down, now! It's not your time to appear!'

'But...but...Yuna-nee, he was so cute and seems sooo cuddly. I want to hug him!'

'I know...I know. But, this is not the time! Listen, I'll hug him for you, but you need to back down now! Please, Alice, you want to help Yuuki or not?' I tried to reasoning with her. Thankfully, she was listening to me.

'Alright...but promise me you will hug him! Pinky promise!'

'I promise! Now, back down until I call for you, 'kay?'

'Okay!'

Then, she finally backed down. Thank God! I don't want my first impression to be 'the cute little girl', sorry, I mean no offense to Alice, but I really need to do this alone. I want to make sure that this weapon is effective.

"Why are you still standing there?" Oh, damn...I might look like a fool who stood stiff at the entrance.

"Nurufufufu~ she might be so surprised to see me in person." The octopus said while his face changing color into yellow with a green stripes. "Oh, of course not sensei. I just took my time to get used to my surrounding." I said and walked to their place. I stop walking and face my new classmates. "Yo! Name's Hina Yuuki. You just can call me Yuuki."

"Welcome to the class, Yuuki-san. You do know what we do in this class, don't you?"

"Of course, sensei! I can't wait to show my skill to assassinate you!" I smiled and offered a handshake to my new tako-sensei. I heard some of the classmates gasped and realizing a nervous atmosphere around my sensei. He looked at my hand nervously and I sweatdropped. The super dangerous creature nervous of a handshake?

"What kind of terrible attitude you have, sensei. I offered you a handshake, shouldn't you take it? If you're afraid of me trying to hurt you, see my hands are clean!" I assured him. Honestly, I just want to introduce myself nicely.

"O-Oh H-Hai! Sensei is really sorry for not appreciate your hospitality!' Then he took my handshake offer.

"Whoa! I thought we would see something like Karma did again." one of them said, it was a blonde girl. Well, I didn't know what exactly this Karma guy did with a handshake, but I think it's one of good show since sensei terrified of a handshake now. Or that's just his act to pretend that he's weak?

"Are you an alien?" I asked him quickly after broke my handshake. "Rude! Sensei was born and grew up in Earth! Why is everybody call sensei an alien!?"

Well, because you're not look like a human...

I laughed and put my hands into my jacket pocket, "Gomen, sensei. I didn't know that. But if you're from Earth, why would you destroy the moon? Why you also want to destroy the Earth? And if you destroy the Earth, where would you leave to and stay then?" I moved around as I threw him the questions.

Sensei and the entire student sweatdropped at my fast questions attack. Even I felt Karasuma-sensei irked at me. "A-Ah...T-that's a lot of questions, Yuuki-san. And Sensei's afraid can't answer those."

Well, no problem if you can't answer that, at least you've eaten my bait.

After sensei said that, his legs melted and he gasped before move away from me with an incredible speed. In a blink of an eye he moved to the back of the class. Damn that speed! He is really worth of 10 million yen target.

"Ah...it's really effective then!" I grinned while taking out my hands from my pocket, along with something that I've been hiding. A powder that originally a bb pills.

"I thought if I face you head on, you could easily escape. So I grind those bb pills last night, and sneakily, threw it on your legs right when I asked you those questions, sensei. It took time, yes, and not really giving much damage, since it's in a small particle."

The whole class turned silent. Shocked, is on their faces.

"Be careful, sensei. I could kill you in a way that you least expected." I smiled wickedly at him. This small damage would be turn much bigger by each day. 10 million yen is surely mine.

"Well then...shall we begin our class today,sensei~?"
