A Supernatural Spin-off of Yurara!
Rasetsu Hyuga works for an exorcist agency where she uses her special powers to banish evil spirits. There's a story behind the red flower mark on her chest though--it's a memento left by a powerful spirit who vowed to claim her on her 20th birthday. Unless Rasetsu can find true love by then, she is fated to become his...
When the evil spirit shows up on Rasetsu's birthday as promised, Rasetsu and her friends engage in a final showdown against it. Will Rasetsu be able to defeat her demon and live? Or will this birthday be her last?
