Kirigi has been considered a legend and has possibly existed since the feudal struggles of old Japan. He's considered a legend among ninjas, and feared above all else.
When several members of the Hand failed to kill the man known as the Gladiator, the Hand's leader (the Jonin) called forth Kirigi to finish off the suviving ninjas and to kill Elektra. A group of ninjas lured Elektra and Daredevil to their secret hideout. When they separated the two, Kirigi attacked Elektra, but she was able to stab Kirigi's chest with both her sais. However, Kirigi pulled out the weapons and the two continued their fight until Elektra grabbed his sword and stabbed his chest once again. Wounded, Kirigi ran off, leaving the Jonin alone with Elektra.
Kirigi wandered the streets of New York, killing anyone who was in his way. He found an abandoned church, within which he was able to meditate and heal his wounds. Once fully healed, he continued to hunt down Elektra. Locating her, she led him to a warehouse, and ran him down with a semi-truck, which subsequently exploded. Still, Kirigi rose up once more. Ultimately, Elektra cut his head off with his own sword, believing him to finally be dead.
The Hand broke into the city morgue to steal his body, but they were opposed by the Black Widow. After a short battle, the ninjas were able to leave with Kirigi's body. Soon, they successfully resurrected him, and this time they sent him after Stick, Elektra and Daredevil's mentor and leader of the Chaste. Kirigi found the Chaste's headquarters and attempted to kill Stick. However, Stick and several members of the Chaste killed Kirigi once more, and this time destroyed his body, so the Hand can no longer bring back their master warrior.
