Kitsunebi-ryu allows the user to generate, attack with, and cut through fire.
This ability allows Kin'emon to cut through flames and explosions while completely protecting himself from harm, giving it a strong defensive use. For offense, the generated fire enhances Kin'emon's regular attacks and is useful against creatures susceptible to heat.
This style can further be used for first aid, with the fire being capable of cauterizing potentially deadly wounds.
Homura Saki (焔裂き,Homura Saki?, literally meaning "Flame Split"): Kin'emon slashes his sword to slice an incoming fire attack. This was first used to cut through an explosion caused by pieces of Smiley and was first named when slicing through the flame breath of one of Vegapunk's dragons. This attack was used again against Kaido, slicing through his Bolo Breath and wounding him at the same time. Zoro later uses this technique to split the homie Prometheus in half. In the VIZ manga, this is called Blaze Slice, and later Flame-Rend. In the Funimation sub, this is called Flame Split.
Karyu Issen (火柳一閃,Karyū Issen?, literally meaning "Firework Flash"): Kin'emon leaps into the air to attack with a powerful flaming slash. This was first used to defeat one of Vegapunk's dragons. This technique is similar to Zoro's Hiryu: Kaen technique. In the VIZ manga, this is called Fire-Willow Flash. In the Funimation sub, this is called Flaming Flash.
