Onihunter Yuna

Yuna Masuda is an ordinary high school student until a fearsome man named Tirr enters her home one night and murders her family. She barely survives and awakens wounded at the hospital where she discovers soon, that she is no longer the same girl as before.
A mentor takes care of her and tells her that she is now part of the shadow realm, the world of the Oni. Slowly she explores her new abilities and vows to get revenge on the murderer of her family. New friends and allies are there to help her with her quest.
In addition, she meets a young man who develops a romantic interest in her, which is mutual, if there just would not be the thing with the Onihunt, which repeatedly messes up her life completely.

Will she be able to avenge her family? Will she experience the tender touch of the first love? Can she find a way to balance her life as an Onihunter with the life of an average high school student?
And is there a chance that she might lead an ordinary life without monsters someday?
