When the Royal twins Remus and Rinda are forced to flee by the invading Mongaul army, they are saved by a mysterious leopard-headed warrior. His name is Guin, but he has no memory prior to meeting the twins. As night falls, the group are attacked by ghouls and must once again fight for their lives.

With the Mongaul army closing in on the group, Guin decides that he has no option but to stand and fight. As such he lets Istavan and the twins go on ahead, while he doubles back to take on an entire legion of soldiers single-handedly.
