Who is this? Saikou nisho! Hikari kara umareshi kage! Shadow!

By pressing the Drab Claust at the pommel of the Kougouken Saikou, Saikou's light illuminates to summon Saikou Shadow who emerges from his silhouette.

Though merely a puppet that Saikou can control, Saikou Shadow has a multitude of abilities on its own. These include being able to turn into a dark cloud for quicker movement, and being able to turn intangible.
