Dual Blades

**Dual Blades** (二刀流, *Nitōryū*?) is a Unique Skill that belonged to Kirito prior to his death on the 75th Floor. Following his death, the skill was then passed on to Shiranami. This is a skill that allows the user to utilize «Sword Skills» through two blades simultaneously. The skill is retained in «Spell Blade Online» with certain prerequisites.

## Skill Description

Dual Blades is a Unique Skill that gives its user the ability to effectively wield two swords at the same time and use «Sword Skills» that utilize both swords with it. Essentially, without this skill, one cannot practically wield multiple weapons as it is already a well-known fact that one can dual-wield, albeit highly impractical because one would still be limited to single-use sword skills one blade at a time. (Of course, a user of Skill Connect can bypass this problem although they would still be slower than the actual Dual Blades user.)*[citation needed]*

In *SAO*, the prerequisites of obtaining this skill are to complete the «One-Handed Sword» Weapon Skill and have the fastest reaction time among all players, as designated by «Cardinal». This "reaction time" prerequisite is eliminated in *SBO* and instead replaced with performing 10,000 successful executions of «One-Handed Sword»-category sword skills; if the sword skill used is a multi-hit combo, all hits of the skill must land for that skill used to be counted towards the cumulative.*[citation needed]* It is also implied that ambidexterity is a requirement to obtain this skill, however, this was later debunked by Akihiko Kayaba who instead said that it was nothing but a soft requirement as the system simply '*preferred* a player who was ambidextrous and can make efficient use of both hands.
