He now spends his time chasing two jealous women. When one of them is dying, the Joker goes back in time in an attempt to save her.

En route, he encounters a strange ally called Meiyan, a girl who is half-human and half monster. As Taka and his new friend set off on a fantastic adventure they will face many hardships and battles and may very well decide the fate of humanity and the entire universe...
