Wataru is Nagi's fiance who is actually in love with Isumi. The engagement was set by Enkyou Tachibana, Wataru's grandfather and current head of the Tachibana family and its assets. Wataru owns and lives in a video rental shop, and wholeheartedly believes that if he works untiringly, he will someday be able to surpass the Sanzenin fortune.
Wataru can be both strong headed and stubborn like Nagi. He was initially hostile when first encountering Hayate at Nagi's mansion. However after seeing his kind and considerate personality at work various times, he warms up to him and vowed to become more like Hayate one day. Despite being 13, he can be both kind and responsible.
