Rikido Sato, also known as the Sweets Hero: Sugarman, is a student in Class 1-A at U.A. High School, training to become a Pro Hero. 

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. The fact that Rikido was caught off guard by this overly positive reaction suggests that he himself doesn't think much of his own abilities as a confectioner.
