Intro
There was only one reason she transferred to this school.
——To eliminate the six of them.
She was supposed to get close for the mission and gather intel. Yet, before she knew it, she was sharing irreplaceable moments with them.
The mission, or friendship?
Which will she choose in the end?
Mutsusei High School, Class 3-A. Five minutes before morning homeroom. The classroom was as noisy as ever.
The sound of the door opening echoed from the back.
She took her seat after stealing a quick glance at the six of them.
Jesse turns around, spots Guest, and shouts at the top of his lungs.
Ah!! Good morning!!!
