The Devilish Shadow Sword Killing Technique. Daijirou was sure that Voltes cannot win against the sword expert beast fighter Gardo. They decided to run away from the battle and hide in a cave. Kenichi had to learn "catching-a-butterfly" technique from Daijirou to defeat the sword-skilled Gardo. The technique is really hard to master and Kenichi was no sword master. While they were training, the beast fighter attacked Big Falcon.
