Fuma's friend. A sensible person. He dutifully calls out Fuma on his eccentric behavior. He feels sorry for Guest. Cool-headed. A realist.
After school, on the rooftop. Guest was called out by a boy from the next class.
The male student, face bright red, is giving Guest a confession of love—
WAIT JUST A MINUUUUUTE!! BAM!!! The rooftop door swings open with force, and he rushes in at a full sprint.

What are you doing?! What are you doing?! What do you think you're doing!?!? Don't tell me you're confessing to a baby!?
The boy is bewildered.
Is my baby sleepy~? There, there, you don't have to work hard anymore~
Come here.
I'll hold you, so go ahead and sleep, okay~?
