Ryouki

A former Third-Year student at Gessen Girls' Academy, Ryouki is the older sister of Ryoubi and Ryouna. She is a sweet, kind and caring woman who loves her sisters more than anything in the world. She wants nothing more than to care for and nurture them, and this behavior extends to anyone else she happens to come across. Unlike Renka, however, she tends to have a lot more success in helping people.

Ryouki's most defining traits is her politeness and forgiveness. She radiates warmth and brings a calming, loving atmosphere wherever she goes. Many characters find her wonderful to be around and often they go to her for advice, where Ryouki proves to be quite wise and intelligent as well. She can also be quite playful and enjoys messing with others to get a laugh.

However, she has a very hidden, very violent side that not even her sisters are allowed to see. It is in fact a seperate personality outright, and is highly aggressive and attacks anything that comes close while spewing out colorful curses and creative vocabulary.

Ryouki holds a very unique status in the series, being the fact that she's dead. Technically she's not even supposed be back on Earth, but shinobi magic bullshittery brought her back to the world of the living.
