Soaring Slash (飛翔切り, Hishōgiri?) is a unique skill in both «[[w:c:swordartonline:Sword Art Online|]]» and «Spell Blade Online» that belongs to Klein. It is a skill that opens a new skill tree with high-level debuff applications and sword skill chains.
Although it might not seem like much, the Soaring Slash unique skill is a skill, like Assassin's Blade, gives out debilitating debuffs against monsters, such as «Bleeding», «Poison», «Confusion», and «Paralysis» among others. Within SAO, the prerequisites to unlock the skill was quite strange as since the requirement that must be met is not system-managed: the player must be able to use Skill Connect 3,200 times.
- Renge - A single very powerful horizontal slash

|Volume 1, The Passing of the Torch Chapter 1, Part 3||N/A||N/A||While not reveaing the true nature of this unique skill, Klein uses «Renge», a sword skill granted by his ownership of this unique skill, to bisect [[w:c:swordartonline:The Gleam Eyes|]]' right arm before he could attack Kirin who was inexorably caught in the post-motion delay of «Savage Fulcrum».|
