Wataru Aikawa

Aikawa Wataru's father is being transferred overseas. Seeing this as a perfect opportunity, Wataru decides to stay behind in Japan and live on his own. Even though he's a new transfer student, his teacher convinces him to become a Library Representative. When his fellow library rep tells him that they're missing a member, he goes out to find her — meeting Rinko for the second time.

He is only called Aikawa Wataru in the manga Love Plus: Rinko Days. In the other mangas and the game, he is simply referred to as ore (俺) or boku (僕) (both are the male form of 'I').
