Minami Yamabuki

Minami is the fourth girl Rokudou rehabilitates who has the general appearance as a bat prior to meeting Rokudou. Originally a loan shark who had scammed out money from hundreds of people, her latest being Manager's parents. In a twist of fate, she meets Rokudou and falls victim to his power and begins lavishly spending her money to impress him. She also gives him advice on how to help Manager stop his parent's loan shark, ironically putting a halt to her own plans. When she discovers Rokudou's role, she becomes despondent when her allies betray her and steal her remaining money. After hearing his plight, she gifts the money to Jin. She later enrolls Amori High the next school year as a first year student.

Her surname in Japanese is based on the Japanese Marigold Bush.
