Shinken Hakkyōken

Shinken Hakkyōken is a "holy" sword created by Katsuhara Youko, wielded by Katsuhara Aiko by using the eight shards of the shattered Demon Mirror.

Appearance
Shinken Hakkyōken takes the form of an ornate medium-sized bladeless sword with a flat end. Its "blade" is decorated with four inlaid diamonds, resembling the design commonly found on the wrapped hilt of a katana, and its forte possesses a tassel on either side. Instead of a tsuba, there is a ornate band guard covering an inch of the blade with tassels hanging from either side of it. The handle of Shinken Hakkyōken is only somewhat shorter than the "blade", and possesses two tassels attached to the ring at its end.

Abilities
Purportedly, Shinken Hakkyōken has the power to take the power of a god into itself and disperse it off into the eight directions. The blade itself reflects the power of the opponent that its wielder is facing; when confronted by the sword while utilizing a great enough power, opponents are unable to even see it due to how bright it appears to be at the time. A blow from the sword results in energy being dispersed in multiple directions at once. Aiko can also reflect attacks back at their users by holding the blade in front of her.

Due to the nature of the Demon Mirror used to create it, Shinken Hakkyōken is also able to interact with the shadows of Limbo: Border Jail and other such techniques. It can even affect spirits of the Pure Land such as when it was originally used to return the soul of Katsuhara Kanna to her original body. In cases such as this, it is a simple matter of the soul and body being viewed equally by the mirrors on opposite sides of the sword.
