Sky Fang (空牙 Kūga) is originally a ranged shooting attack of Signum, cast with Laevatein's Schwertform to launch a mana slash in a way similar to Erio Mondial's Luftmesser. Since ViVid, Miura Rinaldi also has a namesake cross-range kick attack, launched with Star Saber's leg gauntlet. It is not known if hers is a variation using Star Saber as the sword (and can also be fired like a shooting attack), or merely a credit to Signum's teaching and training at Yagami Dojo. It can also be used under Sword-drawing, and Corona Timil also manages to imitate it with Nephilim Fist.
