Kitamikado Ayaka♀

Ayaka is the elder sister of Ritsuko. For one of the ”Maidens of Vincennes,” Ayaka has a surprisingly laid-back and fun-loving personality. But these quirks tend to lead to the other girls giving her the cold shoulder. Because of this, she doesn’t have a title, despite her great beauty and amazing figure. Instead, she’s simply known as ”The other Kitamikado.” She eventually decides to join the White Lilies.

Her preferences lie on the side of reform, but since she’s graduating this year, she’s not that invested in it. She’s very interested in the protagonist, though, and teases him a lot as a way of getting closer to him. Her little sister Ritsuko lectures her from time to time, and although she brushes it off, deep down, she loves her sister very much.

”*giggle* You’re cuter than I thought you’d be.”
