Recently, strange bursts of magic were noticed on the coast of Yokohama, of course, an armed detective agency took care of this. Atsushi, Kunikida and Dazai were sent on a mission, after a search they found a gem, of course it was unclear why such a strong wave of magic was coming from an ordinary pebble Just in case the stone was given to Dazai, no matter how funny it sounded, Dazai had the ability to reset and therefore, in case of something, he was always there to prevent the inevitable.

But one day, when Dazai was skipping work, he saw that the gem began to glow, and quite brightly. Dazai immediately touched him to reset his ability, but he began to sparkle only stronger and began to shake in increments, Dazai moved away for his safety, he was worried that something bad was going to happen now, but.. The whole room lit up and the stone turned into..A girl???
