Kirameki

Kamen Rider Shining Demon is one of the many Oni Kamen Riders in the fanfictional series Kamen Rider: Echo Demon.

Kirameki
Kirameki was Tohki's partner years ago until an incident with a Makamou resulted with Kirameki running off, leaving Tohki to fend the Makamou off on his own. As a result, Kirameki was labeled a coward no one wanted to associated with. However, Kirameki joins the group of Oni when he arrives in his kite & suggests getting more reinforcements. Like some of the Oni Kamen Riders, Kirameki has a human form, though it's unknown if he also has a human name.
