~Mission 00 : Start~

Srak. Srak. Srak.

The sound of a pen that scratch across a paper resounding in a room that filled with only one girl. She's sitting there while scanning with her aquamarine eyes through the paper on her hand while the other hand still scratching a pen on the paper.

"Kasumi, you done with those paper already?" The question makes the girl looked up from the paper she's scanning and let out a small sigh.

"I'm just done a half of it, is there something wrong, Kasetsu?" She ask while remove her glasses and look into a boy that identical to her. The said boy, Kasetsu just smile and give her a an envelope and she took it.

"Your next mission, School one" he said and she look up to him. Opening the envelope, she reads the letter.

'Name : Yukari Kasumi

Class : 2-S

Mission Type : Surviving

The King notice that the Teikou Academy will be 'destroy' in two months. We will sent you there in three days, prepare your things until then'

'No words of encouragement... As expected from Eclipse' the girl sigh and rise from her chair.

"Can I leave everything here with you, Kasetsu?" Kasetsu just chuckle and pat her head "You always can count on me, Kasumi. We're twins after all" the girl smile a little and leave the room to her dorm.

~Girls Dorm~

"Ara, Kasumi-chan, going on a mission?" Kasumi turns and see a girl that looked like her but has crimson eyes and flaming red hair.

"Yeah, in three days" she answer and Kasumi lay down on her bed, while the other girl walks to her bed and sit there.

"Where to?"

"It's so rare to see you asking about where I want to go, Kaoru"

Kaoru huff at her cousins answer and sit on the floor, next to Kasumi's bed.

"I'm just asking, is it wrong?" The question makes Kasumi chuckle and pull herself into a sitting position. "Yes it is, because it's rare for you to ask me" Kasumi's answer makes Kaoru sigh and she sit next to Kasumi.

"Well, because even if we're the same age, you're still younger than I am, Kasumi" Kasumi just chuckle and lean herslef into the wall. "I know, I know. I'll be at Teikou by three days"

Hearing that, Kaoru looked at her cousin and Kasumi look at her with confuse look "What?"

"You do realize that's the school that always being targeted"

"I know that, and Eclipse just notice that they'll get 'destroy'"

Kaoru sigh and walk to the door, making Kasumi straighten her position and ask her "Now where are you going?" Kaoru glance at Kasumi and answer her "Talk to Eclipse"

Kasumi chuckle and lean again "Asking Eclipse, or missing him? It's been two months you didn't see him, right?" Kaoru blush a little and turn around to the door "Shut up, Kasumi! Man..." She said then leave Kasumi laughing on her bed.

"There's still three more days... Better go to dojo to practice"

~Three days later~

"Be careful Kasumi, don't do anything that makes you standout" Kasumi sigh at the person's word and turn around to face him

"Yukari Kisetsu, I already 16 years old, and this isn't my first School mission okay, relax" she said and before Kisetsu can say a word, a soft voice interrupt them.

"Kisetsu, stop it already, you make Kasumi just look like a kid" the two of them turn to a girl with mid-back lime green hair and soft emerald eyes with a boy that identical as her, with darker green hair and light green eyes.

"Thanks for helping me, Kaori" Kasumi said and the boy next to Kaori points himself "What about me?"

"What did you do? You didn't do anything Kouki" with that answer, Kouki sigh and look at Kasumi. "How can you be so mean to your brother..."

"Cousin, you're not my brother, Kouki" she spat out and lift her bag. "You got everything you need, Kasumi?" Ask Kaori and Kasumi nod her head and leave the HQ.

"Man... Kisetsu and Kaori sure are a perfect match... Just like mom and dad... Even mom and dad isn't that worrisome" she whisper to herself and walk to the train station. Once she arrive there, she sit on the bench, waiting for the train while eating one of the onigiri that she bring with her.

'Attention all passenger, the train to Tokyo will stop at door 3, please stand behind the yellow line'

Hearing that, Kasumi rise from her chair and going to the train. She sit the one near the door and listen to her phone. After 45 minutes, the trains stops at Tokyo station and she get out from it. She sigh and look at her watch

'It's still 7.36... Well I can take a stroll for a while, right?' She thinks and take a stroll to her temporarily school. Once she arrive, the clock is still 7.54 and she proceed to the principle room. She make her own way to the principle room, ignoring all of the people that staring at her and she knock the door twice once she got there.

"Come in" when she heard that, she opens the door, revealing a man in his mid-40 with a black short hair, a pair of brown eyes wearing a formal suites and when he looks at her, he sigh and straighten his position.

"So... If you're here, when is it?"

"According The King calculation, it's two months from now on"

Hearing that, the principle sigh and look at the calendar, flipping a page and sigh again. "Right when the 2nd year are going to field trip..." Kasumi just standing still until the man face her again.

"You're 2nd year, right?" Kasumi nod her head and the principle lean to his table. "Can I counting on you? In two weeks, there'll be culture festival and next month, the 2nd year will go to field trip, making the school got 10 days of holiday, that means no one in school" Kasumi nod before speak up.

"I'm aware of that. From the past three days, I've been looking at the school schedule and I already has a plan about that"

The answer makes the principle smile a little and straighten his position while looking at Kasumi with challenging look.

"Can I trust you?" Hearing that, Kasumi smirk and answer "Sir, you already know what happen to the school that I've protect, you can trust me" hearing that, the principle smile and give her a brown folder.

"That folder contains your uniform, schedule, and anything you need such as the name of the teachers and students" Kasumi nod and bow "Well then, please excuse me. I'd like to attend my first class" the principle nod and she walk out from the room to the bathroom.

'Better change into this first, so no one have to look at me like a stranger... Well, I am a stranger...' With that thought, she change her school uniform into Teikou and walks to her class.

"2-A... Ah, here it is..." She mumble before knocking the door. The door slide to the side, revealing a woman in her early-30 with soft brown hair that put into a high ponytail and soft amber eyes smiling at her.

"Ah, I thought you're late, come in" Kasumi nod and come into the class and the teacher standing beside her.

"Now everyone, you have a new classmate, be nice to her because she won't be long here. Come on now, introduce yourself" she nod her head and turns into the others.

"My name is Yukari Kasumi, 16 years old. It's nice to meet you and let's be friends for this few months"
