Suija is a character and minor villain from Samurai Shodown V.
Suija, along with his brother Enja, was one of the disciples of Liu Yunfei, who helped imprison him when he got possessed by the Dark Emperor. However, he and his brother succumbed to the powers of the Demon World, becoming demons themselves, Suija turning into a power-hungry demon who thinks of himself as a god. They were sealed, but eventually broke free, seeking the Dark Emperor for a spell that could allow them to fuse with a human host.
Upon breaking free of his seal, Suija possessed a shinobi from the Kazama clan, which alerted the clan to their presence. Suija was finally confronted by Sogetsu Kazama, who defeated him and sealed Suija inside of his sword with the help of his sister Hazuki.
