Osomatsu-kun: Back to the Me no Deppa no MakiOsomatsu-kun: Back to the Me no Deppa no Maki

One day, Iyami found a hanging scroll in his home that had been handed down from his ancestors. When Iyami looked at the contents, he found that it was a portrait of a samurai who seemed to be his ancestor, raising his dentures. But Iyami was very surprised. "SYEEEEEEE!" He was very surprised because the samurai who looked like his ancestor did not have bucktooths. Iyami wondered. "My father told me that Iyami's family has had bucktooth for generations," he said. Then Osomatsu, the protagonist of the story, came to visit. Iyami quickly hid the scroll, but Osomatsu snatched it away and looked at its contents. Osomatsu's gut instinct, without any evidence to support it, told him that the dentures depicted on the scroll must be highly valuable treasures. Osomatsu took the stolen scroll to the Dekapan Laboratory, where it was dated and found to have been painted in the Edo period. Osomatsu volunteered to be a test pilot for a time machine that had just been completed and was in the experimental stage at the Dekapan Laboratory, and began to travel back in time to obtain the treasure.
