Sapphire Single Shot Deadly Sword of Light

White Style Fatal Sword Skill - Sapphire Single Shot Deadly Sword of Light is a powerful technique of FUG's Slayer, White in his prime body. White used his strongest Spirit Sword "Cullinan" to perform this attack. After White felt bored with his clash and skirmish against Kallavan, White pointed his Cullinan sword to the sky and then generate a very powerful burst of shinsu to enlarge the size of his sword. After he was done, a giant sword surrounded by six white wings appeared.

When White swung the sword to Kallavan, it created a spectral image of undead king with hood, much like the grim reaper. The resulting attack was too much for Kallavan to block, his right hand reached its limit due to the accumulated damage and his whole body would've been severely wounded if he didn't blow it off. However, it's important to note that Kallavan's "right hand" was already injured due to Twenty-Fifth Baam's Twin Wings - Black and White Floral Butterfly Piercing Technique which almost ripped it prior to that.
