Raikai

This jutsu was created by Retsujō so she could use the chidori's power as she lacked the physical strength or ability to use it. By drawing her chakra into her hand without releasing it, Retsujō amplifies the power of the chidori. She then slams her hand on something she release the lightning through her fingers as streams of lightning that travel in straight lines destroying whatever they touch.

Advantages
The jutsu has two big advantages:
 * 1) Retsujō can put her hand on almost any object be it a person or a tree, using this Retsujō could place her hand on water and electrocute anyone in the water.
 * 2) Retsujō can modify the position of her fingers in order to somewhat control the direction and power of the streams.
