Kōyō Ozaki/Relationships

Kyouka Izumi
Kouyou is very protective of Kyouka, having taken a liking to her due to their similar abilities and seems to see her past self in her, acting as a maternal figure to Kyouka. Initially, she fights to bring Kyouka back to the Port Mafia, as she strongly believes, due to her past, that killers like herself and Kyouka can only ever live in darkness. However, she is later willing to make a deal with Dazai to ensure Kyouka’s safety and to give her the chance that she herself never had to live a life in the light, showing that she cares very much for Kyouka.

Chūya Nakahara
Chūya Nakahara is like Kōyō Ozaki’s student. Chūya usually calls her Ane-San(formal version of sister) whilst knowing she didn’t really like it at first.
