Yaci Izanagi (十六薙 夜血, Izanagi Yachi) is a character who appears only in Samurai Shodown: Warriors Rage. He is voiced by Shin'ichi Noda.
He is one of the most formidable warriors dwelling in the streets of the prison island of Ritenkyo. He makes a living as a free-lancer bodyguard with his friend in crime, Haito Kanakura. His life changes when he meets a popular (male) geisha, Namino. Wishing to have a better future together, Yaci promises to cease his life of crime and escape Ritenkyo with him. He starts by turning against his gang and killing its members. Knowing that one of them might kill Namino, he sets out to save his lover.
He overthrows the Razor Trio in his ending and reunites with his beloved. One of his comrades, bitter at Namino for "changing" his boss, hurls his sword at them. Namino takes the blow and an infuriated Yaci kills the assailant. Desperate to uphold his promise, he takes the wounded Namino to a boat on the shores of Ritenkyo. To his dismay, Namino dies shortly after they set sail.
Unlike his partner, Haito, Yaci is quieter and haughtier when he's on the job. He thinks highly of himself and isn't afraid to let others know about it.
In Kunou Seishiro's story is revealed that Yaci feels compelled to drink blood, like a vampire would.
- Poisoned Dagger - Yaci can throw poisoned daggers which will slowly drain away his opponent's life.
- Smoke Screen - Yaci can throw a handful of dust to stun nearby opponents, allowing Yaci to land a hit.
Yaci's fighting style is the base for Mugenji and Yuda. This style is based upon the use of reversals, stuns and a projectile which will drain an opponent's lifebar throughout the match. As his weapon has a saw-edge, it produces a unique grinding sound instead of a generic slash sound on every contact with his opponent's flesh.
Yaci is fastest and weakest of the three. He excels at long-range combat due to the speed of his projectiles. His normal attacks tend to push his opponents away. His stunning slash has one of the longest reaches in the game and is fast enough for him to take the initiative.
