About
Store description and overview from Steam.
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!
Create unique builds by strategically choosing cards and talismans that suit your play style!
Explore a Japanese-style map with random battles, treasure, stores, rest areas and a plethora of events! Each chapter consists of three acts and each act consists of ten mini-levels. Conquer them all for a challenging boss encounter.
Roll six elemental die to determine the cards you can play! To keep or to reroll... The choice is yours! Just make sure Manari doesn't get hurt. Her clothes tear easily...
When the battle gets tough, you can always count on the money-grubbing Yutaka to lend a hand! She also sells talismans and ninjitsu to help enhance your deck!
Earn Sacred Jewels after each battle and use them to boost Manari's ninja level. Each level grants permanent upgrades that will definitely come in handy during battles.
In this world filled with demons and tragedy, do you have what it takes to lead Manari to her happy ending? Immerse yourself in this epic drama with full voice acting.
Enjoy over 20 animated H-scenes, over 200 different CG variations, and almost every naughty act and position you can think of! There will also be plenty of cute feet, even in the non-footjob scenes, if you're into that...
More importantly, if you're not a fan of intentionally losing to collect all H-scenes, Agu can also transform into a demon, allowing you to enjoy the same scene as the pair try awkwardly to adjust to this development.
