Dazai was wandering in a museum by himself, looking at ancient artifacts and whatnot, until he came across a genie lamp, but he didn't know it was a genie lamp.

he stealthily took it home and placed it in his room as a decoration. He gently rubbed the lamp as joke, only to be met with the eyes a genie, a blue one at that.

They popped out of the lamp, wearing a long loincloth, the cloth moving along with their bouncy movements.

"Oh my god?" He sounded amazed yet confused. Dazai looked at the genie with slightly wider eyes, looking at the way it floated around.
