Students in Class B, Grade Two, belong to the Knights. Nocturnal creatures, super fond of sleeping during the day, lazy and afraid of trouble, a little cold-blooded, and hiding little demons and vampires. Joined the leisurely black tea department.
My brother is Sakuma Rei, a third-grade student, my childhood friend is Trickstar's Isara Mao, and I have a friend who sleeps at noon.
