Ginsei

Ginsei is an eye-patched figure with silver eyes and a strained history with Ioryogi, his former mentor and namesake. Often appearing as the shadow of a young man, he frequently challenges Ioryogi to combat and remains deeply skeptical of Ioryogi's bond with Kobato. Driven by a private desire to see Ioryogi return to "Heaven," Ginsei stays a watchful presence, holding intimate secrets about Ioryogi's true nature.
