From The iDOLM@STER: SideM Unofficial English Wiki

Hello, this is "Kouhei Kamiya" (神谷幸平). He is a character of mines.

His name comes from one of the characters, "Yukihiro Kamiya" (神谷幸広).

His name can also be read as Yukihira Kamiya, although it would sound much less original if done so.

I will try to help with event images and such.
