Matsushita Ryouhei

A freshman at Shiromiya Academy and Kaname's best buddy.
Ryouhei is easygoing with everyone and a great guy who doesn't see people through biased lenses.
He ends up in a different knight order than Kaname, but his duties are limited to filing paperwork and running errands.
Ryohei becomes the ultimate helpful friend, sneakily sharing valuable bits of info he picks up from his paperwork tasks with Kaname.

He's a bit envious of the protagonist's life among only ladies but also offers comfort, knowing that the reality is much more complex than one might imagine.

"It's funny, right? Here I am in the knight order, and all I get stuck with are errands, even after they called me a promising talent."
