Ryouna

A First-Year student at Hebijo Clandestine Girls' Academy (and formerly Gessen Girls' Academy) and a member of the Elite team, Ryouna is defined by her extremely masochistic and sex-crazed personality. No matter the time or the place, Ryouna is seemingly always in the mood and often goes out of her way to bother people, either to satiate her masochism or lust. Because of these qualities and her lack of a filter, many characters are weirded out by her and prefer to avoid Ryouna whenever they can.

In spite of these special qualities, Ryouna is a very loving and compassionate person, being much more soft and understanding compared to her sister, Ryoubi, and is very loyal to her friends and family. She can also be serious on rare occasions, normally if there's a present threat to someone she cares about.

Overall, she is a very free spirit and doesn't care about how she looks to other people. She also happens to be really gifted in dancing and has an intense crush on Haruka.

But, if you're looking for a really kinky time, Ryouna is your girl.
