*married skk au where Chuuya is an ada member and he and Dazai brought their child to work*
Dazai: Chibi, we know where the serial killer is. Me and Kunikida will go arrest him. I need you to take the baby.
Chuuya: No, you need to take the baby. I have to go right now.
Dazai: So what do we do???
Chuuya: I guess we can call that creepy babysitter we interviewed this morning.
Dazai: Turned out that babysitter is the serial killer we are looking for.
Chuuya, yelling: Even better! Two birds, one stone. We bring him to you!
Dazai, yelling: We're not giving our baby to a serial killer!
