Chikara

The Human Sword Chikara (shee-kah-rah) is the legendary artifact of Airi Rivena, given to her by her foster brother Nico Ruiz.

=Appearance= Chikara is a dull, short, light grey blade with a solid dark grey hilt. When transformed in its overpowered state, the hilt turns green, and the blade extends to the length of a longsword, despite being a one-handed sword. The blade itself becomes a shiny stainless steel.

=Powers=
 * Overpower - Chikara's user temporarily overpowers themself, increasing their speed and strength by massive amounts. They are able to move so fast that they look as if they've teleported. This uses a lot of energy though, so the user may often pass out after using it. They also can only do it once a day as well.
 * Wind Slash - Chikara is able to do a rare move; Wind Slash. It launches a powerful, fast-moving crescent-shaped wind projectile at the foe.
