Tsukage Munechika, the youngest brother of the Sanjo family, was a sword made by Sanjo Munechika in imitation of Mikazuki Munechika. It was once given to the great onmyoji Abe Seimei by the emperor, but was lost while Abe Seimei was in possession of it, and is unknown to future generations.
He accidentally came to this world, lost his memory, and was chosen by Fox Nosuke to become the Judge of Gods.
