Notes/Trivia

 * Parts of the iM@S fan Community worldwide (especially with some fangirls) tend to make artworks and fanfics where he is with Haruka Amami in which is called the Ama Ama Combo. Moreover, he and Haruka interacted to each other for a while in the first episode of THE iDOLM@STER: SideM Television Anime series.
 * For a little part of the Goof Troop/THE iDOLM@STER Cross-promotional Crossovers, he will make an appearance in person (though the creator has gotta think about it).
