The Grin family is the most mischievous and flirtatious family known in the society. Anyone who goes by the last name Grin are said to be unlucky being a victim of a member from the Grin family. Being the youngest was hard for Chess Grin since he was the one who truly inherited the quirk of their ancestor, Cheshire cat. It may sound ridiculous as it seems but the Cheshire cat is a real person who had descendants. Chess was the only one to fully inherit the quirk of Cheshire Cat and was envied by his older siblings but he didn't care. Chess Grin, a flirtatious, mischievous, annoying, and daring boy was the exact copy of Cheshire cat. Hoping to put his quirk into use for good he decided to attend U.A and live with his aunt since his mansion was really far and he didn't want to risk reaching school late. Coming to U.A was an amazing choice. Why? You'll find out soon~
