Sword of Kagutsuchi: Stabbing Flame

While inside his Susanoo, Sasuke swipes his Amaterasu sword horizontally, proceeds with a downward stab at the ground that causes flame spikes to erupt, throwing his opponent up in the air, where he stabs them, and sends a final pulse of black flames through the sword.

Trivia

 * When written as "私怨", shien means "personal grudge", which ties in to Sasuke's character after transplanting Itachi's eyes.
