«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. Due to being the first skill in the rapier category, the skill has a remarkably short post-motion delay after usage, allowing multiple «Linear» to be chained in together at a very short amount of time.
Asuna used this skill while fighting against Windwasps. Due to the skill's short post-motion delay and her high accuracy in hitting the monster's weak spot, she soon took the lead in her race against Kirito to kill fifty Windwasps first.
Hearing Kirito asking to switch, Asuna used Linear to strike the centre of a Forest Elven Heavy Warrior's shield, causing the elf to be pushed backwards and making him open for Kirito's Gengetsu attack.
