Name: Shadow Lightning
Type: Katana
Element: Lightning
Effect: The blade gains an aura of black lightning around it when it is near a hollow.
Description: The hand grip looks like lightning wrapped around the handle. The blade itself is black. Its hand guard has streaks of lightning going from the blade to the edge of the guard, they slightly hang over the guard.
History: He found it after a battle with a shinigami. The shinigami had used a lightning based attack against Caligo. When the Shinigami left the blade was next to Caligo with a note saying it was a gift from the Shinigami to Caligo. The weapon was created when the shinigami fused some of his spirit energy into it. He at first gave it to Caligo to keep tabs on him and see if he was a threat to the shinigami, then he decided he would come help Caligo whenever Caligo needed it. He likes how Caligo fights to protect the souls of others instead of destroying them like the typical Quincy did. Caligo kept the sword because he likes to blend in when he's around humans and Quincies typically don't use bladed weapons.
