Lightning Devil.

In a part of the forest close to the mountain where Zirrack had killed more than 10 rugors. The ruler of the territory was investigating what had happened in its domain.

The ruler of the territory was a black panther-like beast that had 3 tails and darkish-blue stripes all over its body. As it walked through the forest, most of its body was shrouded in a dark cloud, giving an evil aura to it.

The beast was an Inazuma or popularly known as the lightning devil.

Inazuma was known for its uncanny speed and proficiency with the lightning element.

Due to beasts being more inclined to nature than humans in the same realm as them, their mastery over lightning was at least a level above that of humans.

Its powers, combined with its body that was naturally made to be a killer, made it able to kill any human on the same level.
