When his class was tasked to sell meat buns for a School Festival, he was in charge of advertising so he made a costume featuring a Meat Bun head he’d name Nikutarou with a lot of effort. However much to Hariko’s annoyance, his class switched to sell Yakitoba instead, so Nikutarou was discarded.
After the festival ended, he meets Nikutarou again having become a Tsukumogami eating all the meat of every meat buns, and Rinne made him wear the Meat Bun Head to purify it. He brought bean jam buns to Rinne and Sakura for the trouble caused, but it is revealed that he also made a girlfriend costume named Anko for Nikutarou.
