Yahata-ya (八幡屋) is a large clothing business owned and run by Ittan-momen yokai. Their merchandise tends to be quite expensive. The business belongs to the Hachiyo who controls the southwest territory of the Hidden Realm. They have both money and power, so to turn Yahata-ya into an enemy is to make a troublesome adversary. The heir to Yahata-ya was raised spoiled and has grown up into a famously idiotic skirt-chaser of a son.
