Lightning Release: Lariat

While using this skill Kirabi skips to his Eight-Tails Transformation only in a humaniod form, greatly increasing his power and speed, as demonstrated using Number Eight to attack Sasuke, blowing off his throat and his entire chest, unlike Naruto it seems that Kirabi has full control over his tailed beast, as seen to easily control it's power and skipping directly to Eight-Tails full transformation. It also seems that in this form he can de-spell Tsukuyomi, using his Beast as a companion for snapping him out of the illusion. From this state he can fully transform to a miniature Eight-Tailed Beast.
