Minowa is a young woman with short light-colored hair that has bangs partially cover her right eye.
She wears the standard JIDA uniform which consists of a long-sleeved black tailcoat with a standing collar. The coat has two rows of gold buttons on the front, light green details including the shoulder epaulettes which has a Sam Browne belt passing diagonally over her right shoulder. Along with that, she wears a pair of white gloves and a white web belt with a gold waist-plate. She also wears the standard black skirt and knee-high black boots.
Minowa approaches Narumi in one of the locker rooms while he is looking at Shusaku's former locker. She says that the locker was given to her and she apologizes for it.
She then says that she was told that the entire Narumi Squad betrayed the Demon Army and was destroyed. She asks Narumi to tell her what happened as she wants to know if its true. He doesn't tell her much and says that whatever the Hiragis say is what the truth is. When she asks if he betrayed the Hiragis, he says he has nothing to say to her.
She says she doesn't care if they betrayed the army, but she wants to know if it's true that Shusaku is dead. Narumi says it's his fault that Shusaku died. He says she should forget about him since he's never coming back and there's nothing she can do about it. He then tells her that obsessing over such things could get her killed. She then starts to tear up as Narumi leaves.
- The name Minowa means "three" (三) (mi) and "ring" (輪) (wa).
