Dokuhime

A child is exposed to poison from infancy through various means, including herbs placed under her cradle, in her bedding, clothing, and even in the milk she is fed. This gradual exposure makes her immune and transforms her into a lethal assassin known as the "Poison Princess." Anything she does—kisses, tears, or touch—can deliver death. Her survival depends on carrying out her mission in a hostile land and finding a way to endure, provided her resolve is strong enough.
