Rikido Sato is a student whose Quirk is Sugar Rush, which gives him enhanced strength but less cognitive ability whenever he consumes sugar. Rikido has an interest in sweets and baking, the latter being a useful skill to have due to his Quirk. He is surprisingly talented at making sweets, conquering his classmates with his food. While he himself doesn't think much of his own abilities as a confectioner, nevertheless, every week in the dorms, Rikido bakes sweets and shares them with his classmates, which he calls “Sugar Time”. He pairs his sweets with Momo Yaoyorozu’s tea to create a gourmet night.
