Half-Demon Shinobi
半妖忍少女

Manari is a quiet Anti-Demon Ninja.

When she was just starting out, an evil demon sorcererer stripped her of her emotions in order to make her the perfect vessel for the Demon Lord's reincarnation. Those emotions turned into three terrible creatures: The Demons of Lust, Wrath and Idiocy.

Everything changes when Manari crosses paths with a seemingly regular man: Miyakoji Agu. He possesses a "Bone of the Immortals", something highly-sought after by all demons for its incredible strengthening properties.

After accidentally hooking up with him, Manari discovers there's more to his "Bone" than meets the eye. By extracting and consuming its rich essence, Manari's ninjutsu also grows stronger, giving her the ability to battle stronger demons.

Follow Manami and Agu as they cleanse the world, one demon at a time!
