God of Dice

The God of Dice (サイコロの神, Saikoro no Kami) is a diety refered to by Gaspar in the original Suikoden.

Information
Should Tir lose to Gaspar in a game of Chinchirorin, after the latter challenged him in the basement of the bar in Kaku, then Gaspar will remark that the God of Dice does not think of much of Tir.

It is possible that this is just a turn of phrase and not evident of any particular belief in such a being.
