Mizkun

Mizkun is one of the Geniuses of the First Hour and the Genius of Shadows. He is sometimes referred to as Mizkun of Shadows (影法師のミズクン). So far, he has only appeared in the Log Horizon TRPG.

Mizkun takes the appearance of a human-shaped shadow. He specializes in providing logistical support and, thus, rarely comes out; he also has the power to brainwash demi-human Monsters. Currently, he is scheming to shut down the magic circuits guarding Adventurer Cities and overrun them with his brainwashed demi-human Monsters.
