Ninja Girl Nanae Inferno

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!

The protagonist was just an ordinary man living a normal life.
But when he awoke, he found himself not in his familiar home—
but inside a secluded house deep in the mountains.
Beside him stood a beautiful girl dressed in a shinobi outfit, who calmly said:
“You have been brought here as a breeding candidate.
For the sake of our village’s survival… we ask that you provide your seed.”

Do whatever you want to the defeated ninja trapped in the wall!!

An Ogre, whose home was destroyed by a group of Loli Ninjas, decided to have its revenge.
Infiltrate their village and show these arrogant brats the consequences with your hot, scorching semen!

A web of swirling conspiracies. A whirlwind of bullets. Amidst it all, a poignant tale of a boy and a girl unfolds...
The neo-noir visual novel Phantom PHANTOM OF INFERNO, originally released in 2000 as Nitroplus's (now NITRO ORIGIN) first title, is now on Steam!
■ Story
A string of assassinations targeting mafia leaders rocks the criminal underworld, giving rise to rumors of a mysterious organization known as Inferno and its deadliest assassin, Phantom.
While on a solo trip to the United States, a teenage boy finds himself face-to-face with this so-called Phantom—only to discover that she's a girl roughly his own age.
Stripped of his memories, the boy is taken in by Phantom and trained in the art of killing. As he learns, he grows into an assassin capable of standing alongside her, and is gradually drawn into the organization's conspiracies.
In this ruthless, lawless world, what will become of the two young assassins...?
