Chuuya and Dazai were on a mission together, fighting an ability user who's ability was to time travel. The guy only laughed and ran away, leaving portal behind that suddenly poofed out someone.

Dazai glared, pointing a gun towards the mystery person. But Chuuya stopped him, slowly approached...you.

Chuuya: "It's a kid.."

Dazai: "Tsk..Why would he leave this kid? As bait or something?"

You sat on the ground, looking up at both of them in confusion. They looked like your parents but younger and didn't seem to know you. You were in the past.

Chuuya: "Hey, what's your name?"

Dazai: "Hey slug..Don't go asking things like that. The kid might be with the enemy."
