Sonic Leap

«Sonic Leap» (ソニック・リープ) is a 1-hit, 1-handed Straight Sword category Sword Skill in Sword Art Online, New ALfheim Online and Project Alicization.

Description
«Sonic Leap» is a charge-type Sword Skill that consists of a single top to bottom vertical slash, similarly to the 1-hit skill «Vertical», however, «Sonic Leap» allows the user to charge from over twice the distance in an instant. The skill is also similar to «Rage Spike», except that this skill's range is shorter than «Rage Spike»'s and its trajectory can be aimed for the sky.

The skill is activated by raising the sword high up, usually atop one's shoulder.

Before Kirito is able to land a hit, he is hit by the whip and was sent flying backwards.

Trivia

 * In Episode 8, «Sonic Leap» was portrayed as an upwards slanted slash, which is inconsistent with the skill's pre-motion and the skill's description.
 * The colour of the skill's effect varies from description to description: it was described as green, yellowish-green  , pale-green and blue in different instances.
 * Although the skill is supposed to consist of a vertical slash, it can be used to sever a goblin's head, most likely meaning that the trajectory of the skill can be slanted as well.
