Class is dismissed and Sota Komatsu leaves his high school, headed home under the hot afternoon sun. Home for him the past two years has been a small gym in central Bangkok, in a room he shares with three other Japanese fighters. Once in his room, he switches his Trinity International School uniform to bright red Muay Thai shorts, his name embroidered on the leg, and reemerges into the Bangkok heat outside, jump rope in hand and ready to start training.
