From the Sin


From the Sin tells a magnificent story about a vast and enigmatic realm. As the protagonist, you awaken to find yourself among the remaining men in a large fantasy-themed post-apocalyptic continent populated by monster girls and otherworldly beings that surpass human comprehension. 

While you attempt to answer the existential puzzle of your unlikely situation, other races throughout the continents struggle in different ways to survive. Over time, mana becomes more and more scarce, leading to sin, bloodshed, kidnapping, and… romance.

What to Expect?

Navigate a narrative full of pleasurable and not-so-enjoyable moments as you meet a wide cast of characters, each with their own compelling stories and reasons. 

Immerse yourself in the visually breathtaking surroundings and lively individuals that populate this sinful world with these well designed and beautiful photographs.

But heed the warning: there is danger everywhere in this world. Monstergirls are beings who possess both the fierceness of monsters and the attractiveness of maidens. They will stop at nothing to obtain your essence and devour your Mana. 

Will you reveal the real meaning of your life and create your own path, or give in to temptation and let one of them devour you?
