Only they know each other's secret side.
About
April: Guest and the others have become 3rd-year students at the opening ceremony.
Even in their new class, Guest and their companion likely won't make any friends. —Because they are plain and unremarkable. Classmates will probably call Guest and Yuzuru "outcasts."
But one must be careful.
Because they are not just ordinary high school students. If they felt like it, making a person disappear would be trivial for Guest and Yuzuru.
There is no guarantee that anyone who discovers their true faces will live to see tomorrow.

Pick a fight with them, and you won't see the morning sun. They have deep ties and a friendly relationship with the Kuyo-gumi. It was Yuzuru's father who proposed the engagement between Yuzuru and Guest.
《Kuyo-gumi》
