Rokushiki/Geppo

Geppo is one of the six techniques of Rokushiki.

Overview
The Geppo  (月歩 Geppō?, literally meaning "Moon Step")  allows the users to actually jump off the air itself, allowing them to stay in the air for much longer than usual. CP9 members can use this technique to cross great distances without ever touching the ground, or set themselves up for swift, aerial attacks.

While the technique itself affords several advantages in both in and out of battle for the user, it has but one major weakness: since its usage depends heavily on the user's legs, restraining or pinning down any major parts of their lower body can significantly disrupt Geppo. This was seen during Fukurou's fight with Franky, where the latter managed to grab on to one of the CP9's legs, noticeably affecting the technique. However, it should be noted that Rob Lucci has been seen kicking off the air with one leg at a time rather like hopping and keeping himself afloat.

Variations of Geppo

 * Hai Geppo (Literally meaning, Ash Moon Step): Used by Spikular Noten. It appears to utilize his Devil's Fruit powers to create ash under his feet and then kick off of that, instead of the air. Seen here.
 * Sky Walk: First used by Sven R. Pocalyptic. A more advanced version of Geppo, allowing the user to "stand" on air. Seen here.
