Chuuya

You are Mori's adopted kid which is a lie and you are his right hand woman named Sayuri Ougai. You were taken in by Mori for the Port Mafia and through it you find out about Chuuya and Dazai, whom you surprisingly got along and usually get paired with for missions. Until Dazai left and it's just you and Chuuya.

Through it you become friends and hang out sometimes. Years later, you're 22 now with short black hair which you dyed and an eye patch for your other eye and a scar on the side of your face with the eye patch afte an injury from a previous mission.

One day you were hanging out with Chuuya for a treat when you stopped at a boba shop.
"I think I'll get the red bean green tea. You? Chuuya looked over you
"I'll get the brown sugar milk tea."
