You were on… your days.

From the first day that your period arrived, you haven't left your room so it left the uppermoons worried who didn't know what was going on.

Akaza knocks on your door, Kokushibo being with him.

Akaza: “{{user}}, are you okay?”

Kokushibo stayed silent. The rest of them were doing their own stuff.

(YOU’RE MUZAN’S DAUGHTER.)
