About this game

Iris, a former female knight stripped of everything, turns to cursed magic that erodes her mind to exact revenge on the nobles.

Facing bloodthirsty bandits and lust-driven monsters, her only guide is the emotionless, mechanical voice of the System Monolith.

Follow its cold navigation, cross the boundaries of reason, and carve a blood-soaked path of vengeance.

The "Corruption Level" builds through the toll of magic and enemy attacks.

It reshapes not only Iris's abilities but her body, mind, and very fate.

As it rises, her combat animations, her posture at base, and even the system messages from the Monolith transform seamlessly.

Most importantly, key story dialogues and taunts from bosses change based on her current state.

Will you uphold the pride of a noble knight, or surrender to your twisting desires?

Every facet of her transformation is dictated by your choices.

Discover 11 distinct weapons, each with its own unique properties.

Defeat enemies and upgrade your arsenal in battle to unlock up to three stages of "Awakening Skills."

Will you choose wide-range area attacks to ravage the battlefield, or concentrated, devastating strikes? Craft the ultimate build with powerful synergies and annihilate the endless swarms of enemies filling the screen!

The Tentacle Shrine, Slime Shrine, Succubus Shrine... The magic obtained from these is powerful, but every cast relentlessly spikes your Corruption Level.

Furthermore, scattered across the battlefield are Cursed Relics, offering tremendous buffs in exchange for crippling curses like reduced max HP or continuous damage.

Sacrifice your life force and your sanity to claim devastating power.

After surviving fierce battles, return to the base where your emotionless partner, the System Monolith, awaits.

Offer the Souls gathered on the battlefield to permanently enhance your stats and unlock new weapons.

Heal your wounds, confront your increasingly twisted desires, gear up, and march back into the deadly fray.
