Zakuto

Yamishogun is the leader of the Army of Darkness and head of Gundam Castle in SD Gundam Sengokuden. He appears in the final episode of SD Gundam Mk-III. Yamishogun may actually be Yami Koutei, the man who leads the Army of Darkness from the shadows in SD Gundam Mk-V.

Personality and Character
Yamishogun is an arrogant leader who likes to keep his identity secret, even from his subordinates. He hides behind a screen and has the ability to use a Replacement Technique to further conceal himself.

History
Yamishogun was responsible for the construction of Zuum City. Immediately after completing it he had arrogantly sent notice of this to the Gundam Clan, inviting them to send a ninja to verify this fact. Instead the leader of the Gundam Clan at Gundam Castle, Shogundam, decided to send the ninja Onmitsu to verify the identity of Yamishogun instead.

During Onmitsu's mission he was blasted in to Yamishogun's tower just as Zakuto was congratulating him on Zuum City's completion. Onmitsu went up and down the tower, passing by Yamishogun's location and eventually managed to take a picture of him, but the picture showed only his silhouette as he had used a Replacement Technique. Yamishogun disappeared when Zuum City was destroyed, however the Gundam Clan believe him to still be alive.
