«Horizontal» (ホリゾンタル, Horizontaru?) is a basic, 1-hit, One-handed Sword category Sword Skill in Sword Art Online, New ALfheim Online and Project Alicization.


«Horizontal» consists of a single horizontal slash that is carried out by first focusing the weight of the body on the right foot before moving the sword back slightly, then lifting one's left foot due to the inertial weight of the sword and shifting the weight to the left side of the body, thus converting the strength in the swinging motion inside the legs and waist from the hands to the tip of the waist into power for the sword swing.

The only difference between a «Horizontal» and a «Slant» is whether the trajectory of the sword is horizontal or slanted.
