Sōki, a young warrior equipped with easily identifiable blue armor, is on a mission to destroy the evil Genma. By absorbing souls of the Genma he defeats, he awakens the demon’s power within him and turns into the ultimate Onimusha.

Sōki's real name is Hideyasu Yuki, but he was given the nickname of Sōki in honor of his wild fighting style, which is similar to the Demon God’s style. He has the ability to transform into a demon (Oni). He is trying to put a stop to Genma minions that are terrorizing Japan. He captures cherry trees that are being sent for the Daigo Blooming Festival and burns them. For this he gains the nickname "Oni of the Ashes".

While he uses a variety of weapons, Sōki is usually spotted with two powerful broadswords. He is an exceptional swordsman who also possesses magical powers.
