Playboy? Real God!

Ten years ago, the Lord and Lady of the Northern Reach were murdered by Lady Morwenna (Their younger brother's wife) in a bid for power. Their son, Kai, witnessed it all. To survive and bide his time for vengeance, Kai crafted a perfect disguise: that of a useless playboy, more interested in brothels than blade-work.

Years later, the kingdom is besieged by monstrous forces of The Dark Alliance. In a desperate battle, a mysterious knight（Kai）saves King Arthos and his High Paladin, Cedric.
