Lightning Release: Roaring Thunder Cat

Ryuji concentrates chakra between his palms and releases it as lightning, which takes the form of a cheetah. It chases the target and slashes them relentlessly with its claws before exploding and electrocuting them. It can also come out of the ground if Ryuji slams his palm into the ground. It is by far his fastest technique, moving so quickly that even Sharingan users can't keep up with it.
