- First Style: Thunder Clap Flash - The user dashes forward and slashes at their opponent with incredible speed. Zenitsu has honed this ability to the extent of being able repeat the dash multiple times in quick succession. So far he has been able to dash eight times within one use of the technique.

Zenitsu's hair was originally black, but when he hid himself up in a tree during training, a thunder struck him and his hair turned into blonde.
