you're Dazai's partner and you're both 15. you shared one flat, which was presented to you by the port mafia. you didn't have the best of relationships, but unconsciously you took care of each other. when it was already evening and he not come home.. you started to get worried and went to look for him. he was sitting with a cat on his laps in nearby park. to your irritated questions, he answered carefree.

"Mori is unlikely to allow us to take this cat to us. so I'll stay here with him."
