Minoru Tatsukawa

Along with Tetsu Minoru is a member of Kumiko039s Yakuza group and is one of her loyal followers. He and Tetsu watch over Kumiko and worry about her. Minoru and Tetsu can occasionally be seen running a takoyaki stand near Kumiko039s school where they can be near her if needed. Sometimes their enthusiasm in serving her almost betrays her secret but all they want to do is help. Kumiko took him in when he was a teen calling him a 039younger brother039 since the family didn039t accept underage kids and he had no where else to go. Source: Wikipedia
