Ranga (嵐牙ランガ, lit. "Storm/Tempest Fang") is one of the first group of subordinates named by Rimuru Tempest. He is an extremely loving and loyal subordinate of Rimuru, who almost always resides in his master's shadow and absorbing his energy until called for or when otherwise necessary. He is the leader of the Tempest Wolf Clan and the son of the previous boss of the direwolves.


Ranga is a very proud and loyal monster. Towards Rimuru he retains many of the traits of a dog such as loyalty, wagging his tail when he is happy, licking Rimuru, being protective, and always wanting to please his master Rimuru.

He is willing to give everything including his own life for Rimuru's happiness and will do everything within his power to make that happen.

Towards outsiders, he comes across as a scary, ferocious beast. He is very blunt with outsiders and does not show any form of politeness. He tends to appear annoyed and suspicious of outsiders.
