Izumi Miyamura is an interesting mix of strong and weak. Not “weak” in a strictly negative sense; he can t seem to stand up to Hori and deny her what she wants even though we see that it takes a toll on him each time (Mizouchi s comment about his red eyes shows us that), so perhaps that s not the right word. He s maybe too accommodating of other people at his own expense – it upsets him, but he roleplays with Hori the way she wants him to, and he ll speak to his middle school bully even though his body language screams that he wants to be anywhere else but there. A piece of this may simply be him trying to avoid conflict, which is both valid and understandable coming from his middle school experience. But it can at times be uncomfortable for the viewer, particularly when it comes to him accommodating Hori s kink.
