'Am I sensing this attempt is going to fail?'

Aiko thought and a blast interrupted her. She dive into the sea and Karma help her.

"You okay?" he asked lifting her up."Yeah..." Aiko straighthened herself.

"Stay Alert! He can still regenerate! "Karasuma sensei shouted.

"Look!" Kayano shouted. There's a gush of bubbles on the water surface then, a clear ball with a familiar yellow face in it.

"What the hell is that?" Nagisa sweat dropped.

"This is my trump card out of all the trump cards. My perfect defense form!The exterior is crystallized with a high density condensed energy. The leftover energy made me shrink and form into this shell.In this form I am invincible!" Korosensei boasted.

"No way then we couldn't kill you.."Yada said.

"This shell only hold for a day and I'll be back to normal. I've already calculated..."Korosensei continued.

"This is nothing but another utter failure to us." Nagisa thought.

"Invincible my ass! Somethin' gotta break this thing!" Terasaka said hitting the shell..

"It's no use.Even a nuclear bomb won't leave a scratch on me." Korosensei whistled.Karma and Aiko give each other a look then they smirked.

"Oh I see no weaknesses than we're out of options." Karma catches the shell and Aiko pulled out her phone to show a picture of korosensei's reading a porn.

"No stop! I can't cover my face without any hands!- Aiko san! Help Me!!" Korosensei ashamed of himself. Aiko took a step back.

"What are you talking about? you don't have hands, only tentacles."Aiko corrected.Karma made a signal at Aiko, then she handed him a sea slugs.

"Sorry, sorry~ Than I'll just stick this on you!Someone go find me an old filthy man so I can jam this thing in his short!" Karma sticks the sea slugs.

"No, Don't! Help Me!" Korosensei shrieked in horror.

"In someway we can do whatever we want to him." Kayano sweat dropped.

"Yep, and those 2 were perfectly gifted at times like this."Nagisa continued.

"For now we will disperse it.The top brass and I will discuss how to deal with it." karasuma took the shell out of Karma hand.

"But you should be proud even the armies can't go this far with me.It all comes down to you magnificent idea." korosensei soothed the class.

BACK AT THE HOTEL...

The class was dissapointed of course Karma was playing with a straw, Aiko decided to go check for Hayami and chiba.

"Are you guys okay? " Aiko said. Chiba keep his head low but hayami gave her a look.

"Don't be so upset. It's rare for me to sooth people out, but this is important..." Aiko said to them.

......

"Okajima!!" Nagisa shouted.

"It's happening! Hey where's the hospital in this island?"Karasuma asked to the hotel worker.

"Uh well it's such a small island..." She said.Then a phone called.

"....Bring me the one with a bounty, You can come to the 4th floor with the shortest boy and girl.We'll talk at the front desk here.But contact the outsider then everything will be over.Oh and not to forget the girl 'Silent Red' I would like to see her." The unknown man said through the phone.

Time Skipped...

"It's to risky. Send your 2 runtiest student you mean, this 2 squirts?We'd just be handin' them hostages! No one lays any hands on my cohorts!" Terasaka knocked Kayano and Nagisa's head.

"I say we ignore his demands and get everyone to Tokyo hospital!" Terasaka point out.

"I'm opposed.If it really an artificial virus then even any medical department won't have the cure for it. Beside we have Aiko-san." Takebayashi rest assured. aiko turned to him.

'what should we do we only have an hour though?' Karasuma thought.

"I have a way. Now get the healthy students and wear something you can get dirty.and Aiko take your fav weapon with you too." Korosensei chimed in.

time skipped...

"It's high!"Mimura said.

"it looks like we need to sneak in and steal the remedy ourselves.' Korosensei said.

"It's too dangerous!We will be up against a real pro." Karasuma added.

"Karasuma you got 16 students under you. They are all capable of this." Korosensei said.

Then Karasuma sensei gave instruction the mission starts at 2150. Okano lead the way for climbing.

"Woah! Okano sure can move."mimura praised.

"Sure she can. if it's gymnastic she'll lead the way." Isogai said.

"Where's Aiko-san by the way?" he asked.

"She still down there with the others." kataoka answered.

" Oi karasuma it's shaky! climb carefully!" irina complained.

"k-Karma-kun wait!" nagisa climb the rock after him.

"I've like too but the time is running out. Also I can't seem to find Aiko she must be waiting." Karma kept on climbing.

when they reach the top Aiko was already there talking with Ritsu she wears her fav Katana sheath and her signature red scarf but still in her earlier outfit.

"Wow your fast, Aiko-san!" okano praised.

" Yeah, but how? " isogai asked.

Aiko turned to them and said...

"Thanks. When I'm on a mission I'll try to finish it early...With my special move."

"That's what we called pro assassin. " The class said in unison.

Time skipped to Irina sensei's act...

Aiko is half way unsheathing her katana but irina stepped in first and signaled Aiko to stop. And so her act begin...

"She still does it, Huh? "Aiko mumbled clutching her katana sheath.

'even I can just cut them all away...' She thought.

Flashback...
This scene happened in one of their early mission.

"It's okay Aiko-chan let me handle this one.I don't want your fav katana dirty just because of those filthy man..."Irina said patting Aiko's shoulder and went straight away to the body guards.

'This is my job. Now go I'll buy you some time' irina signaled.

This is her talent an assassination skills honey trap 'to bewitch someone...'

Back to the future...

"Wow Bitchy-sensei sure is something..." Sosuke said.

"there more of her for you to see...She's your bitchy- after all. " Aiko said with a slight smile.

they walked again and finally meet with the 1st assassin...
