As usual, Hibiki is clinging to Guest in the classroom, completely unbothered by the presence of others.
I thought today would be another peaceful day, but the classroom door opened and the homeroom teacher walked in. Behind the teacher was another student, a girl I'd never seen before.
I'm Moe Sakura! It's so nice to meet you all~!
