Star Fist Punch

is the Ignition Ability used by Rekka Hoshimiya.

Usage
In the same fashion Shinra ignites his feet, Rekka is able to ignite flames around his fists. Once ignited, he thrusts his arms forward in a punching motion and in a karate stance, landing a more powerful blow to the target. Rekka can also punch from a longer distance and make his flames follow through so that if he can't reach the target with his fist, the flames directly hit it.

Trivia

 * This ability is based on a technique in karate, known as Seiken-zuki, which means "to punch with the lead arm". Instead of the kanji "正", however, the kanji for the word "star" ("星") is used, creating a pun.
