Toshiya Hamaguchi

Оригінальне ім’я: 浜口俊也

Hamaguchi is the more excitable and vocal of Suguru’s male friends. He also has the tendency to speak before even thinking. Hamaguchi also gets help with his homework from Suguru. And when Mahoro isn’t around, Suguru allows Hamaguchi to read from Suguru’s “secret stash”.
