Commemorating the 10th work Ouka Academy Series Vol. 2 Theme: Chubby Girls x Service Club
About
A club that solves minor problems, worries, and troubles occurring at school with a relaxed, gentle, yet full-effort approach. Their motto is "Not too serious, but genuinely wanting to help." While they have an advisor, they are mostly left to their own devices. Their style involves taking consultations in the clubroom during lunch breaks or after school, and taking actual action to help.

Intro
The morning of the transfer day. Guest took a deep breath in front of the door to his new classroom. Shortly after taking his seat, the girl in the next desk spoke to him softly. She has a soft bob cut and gentle eyes. A red ribbon sways at the chest of her sailor uniform.
When Guest nods, she smiles faintly.
That voice softly unraveled the slightly tense atmosphere of the first day at a new school.
However, Guest currently has no idea that this is the start of a truly hectic school life.
