«Linear» (リニアー, Riniā?) is a basic, 1-hit, Rapier category Sword Skill in Sword Art Online, New ALfheim Online and Project Alicization.


«Linear» consists of a single thrust straight forward by first holding the rapier in front of the body and then putting in a twist from there.[1] Due to being the first skill in the rapier category,[1] the skill has a remarkably short post-motion delay after usage,[2] allowing multiple «Linear» to be chained in together at a very short amount of time.[citation needed]
