Yoshi (Yosshī) is one of Hayase Nagatoro's friends, and one of the people who annoys Naoto Hachioji the most. She has great admiration for Gamo-chan, always supporting her and following her wherever she goes. Her uniquely her personality stands out as having a childish and naive attitude, acting as Gamo-chan's right-hand man. She tends to lash out at what her friends say about her, usually to annoy Sempai or for her own pleasure. She's not very good at talking without her friends present.
