A different method to perform techniques other than the usage of hand seals is granted to the user. The user places chakra onto the finger, which bursts into red flame, and writes kanji in mid-air, letting the flame trace the kanji into visibility. The kanji is the main name of the technique, which is executed normally. Works only on red oriented techniques (Katon) and can replace hand seals.
