An accomplished cook, Arou makes lunch for Kanade (and Namiki, the uninvited guest), who often mourns the fact that her cooking "wouldn't hold a candle to his". Shy and introverted, Arou opens up to no one but Kanade (and Namiki, his romantic rival with whom he often argues). Although Arou is quite popular and could easily go out with any girl in the school, he would never choose any of them over Kanade because Kanade is always able to cheer him up no matter how depressed or unhappy he is. Called Arou-kun by his friends. Even though he and Namiki fight a lot, they actually really care about each other.
