Naoya Kayashima works as a hairdresser at a beauty salon in Omotesando, Tokyo. He is a popular and famous hairdresser, who is active in media. He is very sarcastic and condescending however this is to hide his true emotions. He is a realist and doesn't like other people knowing too much about him until he warms up to them, not even giving his name at first until Yuta helps him. He is hardworking and wants other people to put in effort rather than mooching off others.
