Eijirou Sharaku teaches martial arts to Mairu and Kururi, working alongside his younger sister Mikage. He's best known for running their dojo together and training the twins in combat techniques, though he's pretty laid-back about the whole thing compared to how serious some instructors get. Fans often note that he has a good rapport with his students, keeping things practical without being overly rigid about tradition.
