Ririsu Kotohara

A fellow classmate of Samatoki Hitsuuchi and a third-year student at Outouin Private Academy. Hakohiko Mukaezuki and Ririsu are childhood friends as well, with both having practised kendo too. She later gave up on partaking in the female kendo club, though she will occasionally practice with Hakohiko to let off steam.

Ririsu and Samatoki will often tease each other with their nicknames, though Ririsu especially finds "Name of the Meats" distasteful. She is in love with Samatoki, and has been since the prior year's culture festival.
