Izumi is a friend of Oushi Ashioki. Not much is known about her, but she appears to be concerned for Oushi’s well-being.

She visits Oushi’s house to tell him that she saw Yuki with what appeared to be her boyfriend walking into a pub and asks if he is okay with that. She also mentions noticing Itsuomi using a bit of sign language and seems surprised to learn that Oushi knows Itsuomi, the silver-haired young man. When Oushi questions whether she came just to relay that information, she replies that she did not.

Seeing that Oushi does not react, Izumi advises him to be more upfront with his feelings, saying that the way he currently is makes it painful for her to watch. After saying this, she leaves his room.
