Spinning Shield

«Spinning Shield» (スピニングシールド) is a Defensive category Sword Skill in Sword Art Online, New ALfheim Online, and Project Alicization.

Description
«Spinning Shield» is activated by thrusting the sword forward and upward. The sword then begins to spin like a windmill, with the user's fingers acting as the pivot. In just a few seconds, the sword reaches a speed that makes it invisible to the human eye, making it look like the sword had become a half-transparent shield of light. Although the skill allows blocking even major attacks, powerful skills still cause minor damage, as it is impossible to completely block such an attack with the skill.

Trivia

 * A modified version of Spinning Shield was included in «Dengeki Bunko Fighting Climax» as one of Kirito's special moves for defence and limited offence.
