Appears in Sword Art Online: The Rain in our Souls

Darkness Blade appears in Sword Art Online: The Rain in our Souls as the Unique Skill that is bestowed upon the player with the highest number of Player Kills: PoH.


Darkness Blade causes all attacks from the user's primary weapon to deal true damage, that is, to bypass all defensive modifiers. In addition, the user may also use Sword Skills exclusive to Darkness Blade.




  • Darkness Blade was one of four additional Unique Skills revealed by Kawahara Reki, under the pseudonym Kunori Fumio, when the Sword Art Online series was still running as a web novel.
