I dont know how this one snuck past me.
The official synopsis: "The narrative follows a scorned geisha who creates a magical cup made of tears that causes any man who drinks from
it to fall under a stasis of permanent sleep. One night the cup is stolen, setting off a chain of events that threatens civil war amongst the clans. Taro, a once gifted samurai, and his companion Jin set out to find the cup and the one who can break the spell before inner turmoil."
