Yasumasa Sakakibara is a loyal officer of the Tokugawa army and a member of the Four Guardian Kings of Tokugawa along with Tadakatsu Honda, Naomasa Ii and Tadatsugu Sakai.

Samurai Warriors
In Samurai Warriors, all of the Tokugawa guardians were generic NPCs (until Tadakatsu became playable in Xtreme Legends). He is one of the warriors who fought at Mikatagahara and Nagashino against the Takeda. In Xtreme Legends, Yoshimoto could kill him in battle along with the other guardians.

In Samurai Warriors 3, he helps the player on the Oda side out at Anegawa by helping take a key garrison in the region. He will also be among the Tokugawa officers who would fight the Takeda alongside Oda at Nagashino.

Kessen
In Kessen, he doesn't fight at Sekigahara. Instead his only appearance after Sekigahara is won by the East is Harima. After the battle is won, he is replaced by his son Yasukatsu. He is seen in the East's opening cutscene at Edo mentioning Mitsunari would trap the East between Uesugi and himself.
