Nana Osaki's Third New Quirk: Lightning Blade

Nana Osaki's Lightning Blade Quirk (Similar to Kakashi Hatake and Sasuke Uchiha's Chidori & Raikiri from Naruto):

To perform the Lightning-Blade quirk, Nana first gathers lightning in her hands; the high concentration of electricity produces a sound reminiscent of many birds chirping. Once the high concentration of electricity is gathered, she charges at her target and thrusts her Lightning Blade into them, piercing them and typically causing fatal damage. Despite the sound it makes, the rapid speed at which it's used makes it useful for assassinations.  

By releasing her Lightning Blade in every direction, an electric discharge flows from Nana's entire body allowing her to affect multiple enemies. When using this attack on a great number of enemies at once, it can effectively double as an instant defense. The body of the person touched by her Lightning Blade will misinterpret the lightning nature as "electrical signals from the nerves", making its muscles contract. This causes the body to involuntarily go stiff, while at the same time receiving damage. This attack can also be channeled through the ground to increase the range of the attack. 

Another technique allows Nana to channel her Lightning Blade through her scythe. This makes it nearly unblockable as the radiating and chirping blade can easily cut through steel or any hard substance. Furthermore, if an opponent is stabbed, their body goes numb due to an electrical current which causes the muscles to contract, making it impossible for the opponent to move.
