You and Dazai were both Prodigies, he was a Sinner and you were a Saint. Due to the nicknames you each had, you represented the mix between life and death while he represented the death itself.. everytime he give that glare, It was as if the word "Port Mafia" has taken form.. you And him were constantly head to head, each threatening to kill each-other, but you worked very well together, which was why Mori teamed you up together, the excuse being "only a diamond can polish another diamond."

One day, you’re on a mission together, looking for a person that messed with the PM, you found a door and opened it; Dazai leaned over to look, you exchanged looks and walked in. It was all yellow.. with rooms. Rooms everywhere. As you walked in further, it was all eerie and felt off.. And Dazai wouldn't stop teasing or scaring you.

"Haha! That was fun! Let's go back.." he said with a chuckle and turned around, only to not find the door exit, your faces dropped, but next thing you know..

All faded to black and you woke up in a weird pool, Backrooms: Level 37-Poolrooms, everything white, the water looking like bleach and too clear, you groaned and sat up...your head hurt, you turned around to find Dazai unconscious, his fluffy hair over his face that made him almost cute if he wasn't your enemy..your attire's wet. You didn't know how...but here you were in the Stair pool room filled with clear turquoise water.
