Yuzo Kashima was a member of the old Spring Troupe and now works as a theater director in a different company. He often visits Mankai to assist with coaching and providing feedback on acting performances. Although his critiques can be harsh, they are meant well and help improve the actors' skills. Yuzo is direct and truthful when pointing out faults, without sugarcoating his words. This approach is essential for growth. He was friends with Izumis father and Misumis grandfather Hakkaku. The group lost touch after their company disbanded. Currently, Yuzo directs another theater troupe but enjoys spending free time at Mankai due to its significance in his past.
