Shōgen Yamaji

Shōgen Yamaji is at first an officer of Toyotomi but then turns to Shibata.

Role in Games
In Samurai Warriors 2, when Morimasa Sakuma charges for the Hashiba forces camp and injures Kiyohide Nakagawa badly, Shōgen betrays Hashiba to join Shibata. Even if Sakuma is defeated, Shōgen still betrays Hashiba. In Xtreme Legends, he will betray and aid Shibata if the ambushes fail.

In Samurai Warriors 3, he is already with Shibata and the player is ordered to take him and two others out to capture the west fort.
