Rihito Amagi (天城リヒト Amagi Rihito) is a supporting character of the second season of the series.
He observes Kaito's progress in regaining his memories (despite his sister being around) while he checks on Lucia and comforts her as she copes with the loss of her emotional bond. Rihito tries hard to get Mikaru to realize that she can never be with Kaito, even though she doesn't want to hear it. He is the one who convinces Kaito to tell Mikaru she is not the one for him when he regains his memories.
In the anime, when Kaito leaves after telling Mikaru that he loves Lucia, Rihito restrains Mikaru from going after Kaito.
It is later revealed that both he and Mikaru are part of the same race as Kaito, leaving Rihito to believe that that is the true reason why Mikaru is attracted to Kaito.
When Mikaru is reborn, he promises that he will care for her and raise her again.
In the manga, it is revealed that Rihito and Mikaru's mother was of Panthalassan heritage, and their father was a scientist obsessed with the Panthalassan and Ancient races. This makes Rihito and Mikaru half-Panthalassans. Rihito's power projected itself, as revealed by his father, in his music, while Mikaru had to suffer from her own blood that was rejecting herself.
Rihito has the power to wield the Staff of Panthalassa through his Panthalassan heritage. When Rihito conducts an orchestra, he might show the cross of Panthalassa on his forehead.
He appears only in the second season, Pichi Pichi Pitch Pure.
Rihito's voice actor is Takahiro Mizushima
