Invisible Swing

Invisible Swing stance

The anime equivalent to Sanada's "Fū," the Invisible Swing is an extremely fast swing that is based on a sword-drawing technique. The fast swing means that the opponent can neither see the racket or ball after it is hit, making the ball seem 'invisible' to the eye. This shot often returns the ball before the opponent has even recovered from the previous shot. Even with good motion vision, anyone who tries to focus on the speed of the ball will only see a blur and their eyes will begin to hurt, similar to Akazawa's Blur Ball.


  • After Echizen's eyes begin hurting and plays with his eyes closed, he relies on his hearing.
