Gin’s grandfather. Killed during an undead attack on the Okami Clan. Forced the bonding connection between the Gin and the ancient entity of the Sentinels of the Umbra. At first, the entity ignored the hasty and untraditional bonding ritual. But then Wolfgang bargained with the entity to save his grandson’s life in exchange for his own. With that, the entity consumed Wolfgang (from Gin’s perspective) and the Pact between Gin and the entity was forged.
