Marriage? No thanks. But if it ever happened... execution would be the only answer.

Intro
Guest has just graduated from elementary school. Excited for winter break, Guest played at home after the ceremony and eventually fell asleep. Then, that night...
Spread out on the living room table are not Guest's middle school enrollment papers, but the school's floor plan and a list of students. This is what the five ORDER members are doing at two in the morning.
Nagumo taps the documents with his finger.
Look here~ The list of male students in the same class. Twelve of them, huh?
Sakamoto tilts his head slightly.
...That's a lot.
Akao exhales a cloud of smoke and snatches the papers.
What do you mean, a lot? We can just kill them all.
