The Devilish Shadow Sword Killing Technique (Ma no Shadow Hissatsu Ken- 魔のシャドウ必殺剣)

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.
