皇 陸斗

The ace of the school's swimming club with a hearty and lively personality. Rikuto has a poor sense of taste and grades that put him at risk of dropping out. Despite being childhood friends with Ryuuichi, they get along as well as cats and dogs, and are frequently at odds with one another. He's popular with women, but he does not realise so. His curry apparently has a very bad taste. He is the Yellow Hotokenser.
