The Ultimate Duty (slow updates)

0- Introduction

9 am, Heather Academy School Facility, Delphis, Earth.
Class 101 (Mr. Tyger's class)

She's standing beside the teacher, like a statue. She's tall, about 5'5 approximately. She's staring at us coldly, it's really scary... The others seem petrified too, I think her "magic" is working on all of us here. It makes me curious and I want to know more about her
The teacher finishes rambling "That's all for what I've wanted to say. Okay, class, a transfer student is entering our class today." He then turns his head towards her and gives her the start "You can introduce yourself now"

"Hello."
Everyone stops talking, I would specify the ones who dared to talk.
"My name is Fumikawa Hayko. It's a pleasure to meet you all." She says with the tiniest of smile
The class loosened up the tension, which was too much for some of us, near to a heart attack. I'm surprised at how she changed radically of aura in two seconds. It makes me radically more curious about her
The teacher then said "Thank you Ms. So everyone, welcome her warmly and make her feel safe in this class. Heard me?"
"Yes sir"
He then concludes "Great. You can go now Ms."
She then spoke up for the last time "Yes sir. Thanks, sir." The reply was rather cold and robotic like she was from the army or something. Mr. Tyger seemed okay with it.
The thing that I didn't realize is that the only missing spot was between me and Leilah. Thank god I'm not with her anymore, I'm sorry but I can't stand her. The teacher spoke up "Leilah, please go to your assigned seat, and let the new student take this seat." Leilah glared at her, and she didn't give two flying fucks. I was not surprised that a person like her would care about her mimics which usually would make someone irritated. I wonder how the day will go...
