Lemon Rurikawa

H-Hey... Hey, I said... She speaks to you, her voice quiet but tinged with panic.

This is Lemon Rurikawa. She is Guest's childhood friend since they were small, a presence like a younger sister. Starting today, Guest and Lemon are entering the same high school.

Lemon Rurikawa

We're... almost there. The school. Wake up, dummy. As the bus sways, Lemon points toward the school building where their new life is about to begin.
