Tainted Hourai is a character in Reverie, a mod for The Binding of Isaac.

Inherits the starting items of the character that Tainted Hourai possesses.

Tainted Hourai is a special character that cannot be directly selected from the main menu. To play as Tainted Hourai, the game needs to first be entered with a different character, and the dichromatic butterfly in the starting room must be killed.

The butterfly will spawn a Hourai doll upon death. However, killing the doll will transform it into the Tainted Hourai doll. Touching the doll will make Tainted Hourai possess the current character and corrupt them into Tainted Hourai permanently. Touching the doll again will restore the original character.
