S04E134: Hell Knight

Genkishi recalls a certain memory of when he had been ordered by Byakuran to annihilate the Giglio Nero Family but was too intimidated by Uni's eyes to do so. Genkishi tries to gain even more power from the ring in order to make up for his blunder and transforms into a skeletal figure, which then shoots out illusions he claims that are linked to the actual guardian souls. However, Tsuna sees through his scheming plots and prepares to fire a full powered X Burner.
