Onimaru

Onimaru is a komagitsune who was once the companion of the late daimyo of Ringo, Shimotsuki Ushimaru.

After the death of his master, he joined forces with Kawamatsu in collecting weapons for the final battle against Kaido and protecting them from robbers. After Kawamatsu was captured, Onimaru posed as a human known as Gyukimaru on Oihagi Bridge, stealing weapons from people while continuing to guard the graves.
