«Vertical» (バーチカル, Bāchikaru?) is a basic, 1-hit, One-Handed Sword category Sword Skill in Sword Art Online, New ALfheim Online and Project Alicization.


«Vertical» consists of a single slash from top to bottom. Although it is a beginner skill, it is much more powerful than a simple, non-system assisted, vertical swing with a sword.

The skill is activated by spreading one's feet out to the front and back and then holding one's sword up as though letting it rest atop one's shoulder.


Instance Description
Light Novel Anime Manga
Volume 8, First Day N/A N/A Coper used this skill to puncture the «seed» of a Little Nepent to draw a horde of the monsters in an attempt to kill Kirito.
Progressive Volume 1, Aria of a Starless Night, Part 14 Episode 2 Kirito activated «Vertical» to block Illfang's attack, but he misreads the monster's move and was not able to cancel the skill in time to block Illfang's «Gengetsu».
Material Edition 16 N/A N/A Kirito defeated a Magnatherium with a single Vertical.
Volume 11 Chapter 5 Part 1 Alicization Episode 09 Humbert Zizek used the skill in his duel with Eugeo and was able to overpower the latter's «Slant».
Volume 11 Chapter 5 Part 1 Alicization Episode 09 After Eugeo's «Slant» was overpowered, he let his sword be pushed back to his shoulder and chained in «Vertical», instantly pushing back Humbert's sword and breaking his posture.
Volume 12 Chapter 8 Part 1 Eugeo used «Vertical» against Deusolbert Synthesis Seven's flaming fist. However, this led to a brief stalemate, after which Eugeo's sword caused an abrupt chill, which created an opening for Eugeo and he changed «Vertical» to «Vertical Arc».


  • In Episode 2, «Vertical» was executed as a diagonal slash from bottom-left to top-right, which would actually be one of the two possible directions of «Slant».
  • In Volume 12 it's not clear whether Eugeo used «Vertical» and later switched to «Vertical Arc» or whether he used just «Vertical Arc», as «Vertical» was mentioned as being used, but this is contradicted when Eugeo says that the first skill he used was «Vertical Arc».
