Souichirou, also known as the head of the Shimogamo family and father to the Shimogamo siblings, is a renowned great tanuki from Kyoto. Respected for bringing together the tanuki community, he once used his shape-shifting abilities to scare off the Kurama tengus during the False Nyoigatake Incident. Tragically, Souichirou met an end when he was consumed as a hot pot ingredient by the Friday Fellows.
