Autograph

Rei is the young but responsible violinist of Altessimo. What he loved more than anything was to share his music, but he lost his passion to play to money mongers. The producer approached him, complimenting Rei on his talent and offering him a position at 315 Production. Of course, Rei was skeptical at first, his unit member Kei Tsuzuki's off personality adding to his initial distrust.

However, over time he began to enjoy his job more. During the practice of a children’s music program, he noticed a boy unable to sing. While the children took a break, Rei offered to sing along with the kid, making the kid very happy. Seeing the kid now smiling and able to sing with the rest, Rei thought to himself how glad he was that he became an idol.

Because Kei tends to zone out and wander off on his own, it is up to Rei to look after him. Still, Rei does not see Kei as a liability, and he highly appreciates Kei’s support and respects his talent. Rei believes that alongside him that he can keep going as an idol.

Rei is socially awkward, not having had many friends in the past. He argues he does not know how to talk with people his age or even just what to talk about. Shiki Iseya helped Rei open up in this respect when Shiki approached him after a joint live. The two went to a cafe to listen to classical music and chat.

Much like Jiro Yamashita, Rei also has an intense love for horses. He is also easily flustered, having been caught acting out of character to discover some of his idol outfits were very feminine. He owns a golden retriever, favoring them for their intelligence and reliability.
