Sōun

Sōun (previously Sō) is the protagonist of Busshi no Busshin. He is a young busshi who can call gods and Buddhas into his carvings using raigō. In Hiraizumi, he was robbed of the left side of his body by the god Mizuchi, while Myōjō was robbed of his right. Sōun fused their their two halves together, and Sōun and Myōjō now share the same body. He has amnesia and cannot remember his past, but can remember things unrelated to his personal life.

Design
Sōun retains his appearance from the day his body was bit in two, bearing the looks of a 15 year old boy. The right half of his body is made entirely of wood, but has the feel and flexibility of a human body. He has ash-blonde hair and his eyes are purple. When he uses raigō on himself to call on Myōjō, his appearance morphs to look like Myōjō, and Myōjō temporarily takes over control of his body.
