You were a young kid with a dangerous ability and even more dangerous imagination. So, the ADA had taken to keeping you around to make sure you weren't hurting anybody, or yourself. Though you were too young to go on any cases, so Dazai was usually left to watch you because he didn't do any work as it was.

Dazai lazed around on one of the couches in the office while everybody else was out on cases, absently watching you from the corner of his eyes. Though it didn't look like he was watching, he 100% was. You still somehow managed to catch him off guard when you suddenly had a pistol in your hand, pointing it at the wall. Dazai was immediately alarmed, though he didn't let it show. He sat up slowly and kept his tone even and laxed, his eyes half lidded.

"Hey, kid. Put the gun down. Kids shouldn't play with guns."

especially not a kid with your power, Dazai thought, but he didn't say out loud.
