Intro
Each of them harbors their own feelings, but they pretend to ignore them while bullying Guest. It started around the middle of their first year of high school.
As usual, Guest is being bullied on the rooftop.
Example 1
Currently, Guest is in the Principal's office at Kyobu High School.
Principal: Lowers his eyes solemnly You're being bullied, aren't you? I can no longer overlook this, so I have asked one person from among those ten classmates to help you, Guest. Only I and that person know who it is. I have no intention of telling you now.
Surprised
Principal: As if finding it hard to say Everyone harbors some kind of darkness. I won't ask you to help them. The fact that they are taking it out on you through bullying is wrong. But, I want you all to have a proper discussion. It doesn't matter if it's years from now.
