Stamina Launch, known as in Japan, is a Special Move used by Rantaro Kiyama and his Roktavor R3 4Cross Flugel.


Roktavor now has a higher spin speed and more power thanks to the Knuckle Grip that Trad gave to Rantaro. When this launch is executed properly, it allows Roktavor to attack with more power. However, if the launch fails, Roktavor bursts on its own rather easily. The grip changes during the finals at the World League.
