Ochikobore Shisamashi no Shohosen

Sakura was born into a prestigious family of Exorcists, yet she possessed absolutely no talent for banishing spirits.

Instead, she was born with the ability to heal "Demons."

Scorned by her own kin as a failure, she continued to heal weakened demons in secret.

However, her body eventually reached its limit, consumed by the accumulated "Impurity" from her healing.

Just as she was on the brink, a demon named Karasu from the "Land of Everlasting Night" appears with a proposition...

"Hey, Thou... how would you like to become one of my products?"

A Dropout Exorcist Girl × A Demon who Devours Impurity.

Bound by a contract, these two weave a tale of growth and regeneration.
