Tempest Wolves are the evolved forms of Direwolves. When Rimuru gave Ranga a name, it triggered a piece of Demon Essence. Unlike his father, Ranga believes in the concept of "All for One." As a result, his fellow wolves also evolved into Tempest Wolves.


Tempest Wolves have jet black fur, which gives a feeling of bewitching gloss and a glossy finish. Furthermore, their length is nearly 3m.


They are fast and don’t show any fatigue. They can run for 3 hour at 80km without taking a break.
