MANARI ~Half-Demon Ninja Girl~

Manari, a taciturn demon-slaying ninja.
On her first mission, an evil sorcerer stole her emotions, making her a vessel for the reincarnation of a demon king.
The emotions stolen from her were lust (“lust”), anger (“fear”), and foolishness (“ignorance”).
These three tormenting emotions eventually transformed into three demons that threatened the world.
Guided by fate, Manari met an ordinary man, Miyakoji Yasuhisa.
Miyakoji possesses no special abilities, but he has a highly coveted item, the “Immortal Bone,” which demons desperately desire.
It is said that consuming it greatly enhances one’s demonic power…
Manari and Miyakoji met under strange circumstances, and it was discovered that the concentrated life force in the Immortal Bone strengthened Manari’s ninjutsu.
Strengthened, Manari confronts powerful demons.
And so, Manaru and Miyakoji Yasuhisa set off on a journey to defeat yokai!
