Class 3-E. A class of the Kunugigaoka Junior High School; Koro Sensei rose from his desk most students noticed and gave him their attention. It was a "standard" day for the class 3-E. It was a Monday of all days, many students seemed groggy or had darkness around their eyes. Koro Sensei began to speak, "Today there will be a new student. Her name is Musume, Ika. Treat her nicely like how you should treat any new student. She may not be used to her new surroundings she never been to a school before but her intellect is exceptionally amazing."

There was chatter throughout the class all curious about the new student.

"Ms. Musume you may walk i-"

Bursting into the classroom came Ika Musume or as some known her as 'Squid Girl'.

She used her tentacles to boost herself onto the teacher's desk.

"Listen up you sucker fish!" The classroom grew silent gawking at the blue haired girl, "Bow before me as your INKvader… I am Squid Girl, emissary of the sea!"

Some students were shocked from her tentacles her tentacles weren't like Itona's nor Kayano's, they were shaped like arrows and twitched abnormally.

Koro Sensei was surprised yet furious that someone would dare jump onto his desk.

He beckoned at her with his tentacles to get down and get off his desk. She glanced at him unimpressed.

She jumped off the desk without her tentacles and immediately slammed her head onto the floor. Bolting up dusting herself off. She tried not to show signs of weakness by yelping in pain or crying she ignored the fact she fell and before started up again Koro Sensei told her red in anger to sit down at once. She pointed at of the student desk in the back of the room.

"Very well my fellow cephalopod I will sit down, but hear me now and obey… I will conquer this entire school from your grasp and this class shall bow before me. Mark. My. Words."

Ika sat down at the desk in the back that was empty. As she sat down she noticed students glancing at her.

"What the squid do you kelps think you're looking at?" she said trying to sound intimidating but came out more jokingly,

Some students murmured things like "what the hell is that thing, is it here to really conquer this school?" and "those were some terrible puns,".

Later on that day...

Math class started shortly after. As expected Ika was at ease doing the work.

When it was time for gym the gym teacher kept looking at her but didn't speak once to her. Ika had no interest in the activities she could care less about learning about guns and how to correctly use knives. Because she felt all she needed were her tentacles.

During lunch she felt out of place no one talked to her yet.

"Hey. Are you really planning on killing all of us?" A girl with short green hair asked,

"Well of course I am! You think a squid like me would go gillin' around for nothing? After all you humans done I won't stand around and ignore for shellfish."

The girl store at her in confusion. A boy with blue hair walked next to the girl with green hair.

"Hello are you liking the school so far?" He asked,

"Well of course not. What school kind of school doesn't have a pool?"

Ika opened her lunch and it was just a container with nothing but shrimp.

"My name is Nagisa isn't yours Ika?"

"Ika? Call me Squid Girl emissary of the sea!"

"Okay… well did you know that we are suppose to plot to assassinate our teacher?" the green haired girl added,

"Assassinate? What the squid is that?"

"You don't know what that means? Well, it when you kill someone with surprise." Nagisa said,

"Kill someone… why would you? Why would you kill a cephalopod that never done wrong to you! What's up with you humans and murder? You kill those who help you. It's not like he's prey he's your teacher." Ika declared,

Ika without letting anyone else react tied up Nagisa and Kayano with her tentacles into the air.

"Mr. Koro Sensei these two humans are plotting to gill you!"

A/N:

I know this is an odd crossover but I just thought it over and thought this would be great.

Please do tell me your thoughts if you haven't already read the Squid Girl manga and anime.
