Mio Kusakabe
One of Sakurai Hinako's best friends, she's dragged into starting the Love Club by Hinako along with Kiryuu Hotaru. Mio's body is developing faster than her friends' and she's quite shy about the fact she has large breasts. She's also quite athletic, having an interest in basketball, volleyball, track, softball and swimming. (All clubs she was considering joining before Hinako started the Love Club.)
