Rinne Natsume lived her life thinking she was just an ordinary schoolgirl. Little did she know about her own secret…
A few months ago, she lost her father when a demonic cult attacked them. But something within her awakened—the power of the “Grim Reaper.” She fought back and defeated the cult members who had attacked her family.
However, her fleeting moments of peace were abruptly shattered as she was captured and imprisoned. Akuta, the leader of the cult branch, held a deep grudge against Rinne for the scars her father had left. And now, a sacred ritual of unholy union between demons and the Grim Reaper was about to commence.
But just then, two wandering exorcists appeared on the scene—Setsuna Shindou and Yuka. Despite their valiant efforts, they found themselves outnumbered and surrounded by devoted cult followers.
In this dire situation, what lies ahead for them?
