Inran Sekai SEDUCE

A band of heroes went on a quest to stop the lewdness spreading across the world.

But the lewdness won, as it often does. Heroes have everything to lose.

Now, your own village is under attack.

You vow to destroy the lewdness, for the sake of your precious little sister!

Save the world (sekai) from the seduction of pornographic vice (inran)!
