The elder Miyoshi brother.
A laid-back monk who enjoys liquor, women, and money. He's experienced both the bitter and sweet sides of life. He was once helped by Masayuki Sanada, so Seikainyudo barged into Mt. Kudo after Masayuki was exiled to offer his personal aid. While he usually avoids conflict and blends in with society, he commits to supporting Nobushige.
