Minoru Tatsukawa

As a devoted follower within Kumiko's Yakuza organization, this character shares a deep, protective bond with Tetsu, constantly looking out for Kumiko. They occasionally operate a takoyaki stand near her school, offering a way to stay close, though their eagerness to serve can sometimes reveal their concerns. Kumiko took him in as a younger brother when he was a teenager, providing him with a home when his family rejected him.
