Fire Release: Phoenix Sage Flower Nail Crimson

The user unleashes a volley of shuriken with one hand, while at the same time exhaling fire-infused chakra onto them in order to increase the weapons' destructive potential by making them capable of inflicting severe burns upon direct contact with either the intended victim or any other object caught within their trajectories.

Due to the chakra-based nature of the flames that surround them, the shuriken will continue to burn after impact, regardless of the flammability of the object that they ultimately collide with.

Trivia
no it doesn't. there's at least 40 shurikens ablaze. and seeing as how i didn't see a stack of shuriken in his hands prior nor did i see him consistently reaching for more (which with that many would take two hands) i don't see how he could make the necessary hand signs, throw 40 shuriken that he never had, and bring his hand to his mouth in the usual fire breathing style. unless they came directly from his mouth. and no im not editing the proper way fixing blind peoples mistakes. having people tell me this isn't the place for speculation WHT RAG. if a talk: page isn't for speculation what is. change it don't change it im not nerdy enough to care. all i know is whatever i put up is going to be taken down. Peace.
 * is the Japanese name for the Impatiens balsamina. is an alternative name for this plant, stemming from its use in producing red dyes for nail polish.
 * In chapter #56, Sasuke uses a rudimentary form of this technique employing the Fire Release: Phoenix Sage Fire Technique and hiding shuriken within the flames for an added surprise attack. However that tactic and this technique should not be confused with each other, as this one employs chakra flow, breathing the flames directly onto the shuriken.
