Rontu Is Dusks older Brother and is a character in Panthereolo. And yes he may be… “Big” but he’s a healthy living wolf who goes on walks and stuff. Rontu used to be in a wrestling club before but after a broken rib and arm incident, he quit and decided to just get lazy, and ate a lot. But he cares for his family and is always there to help Dusk out, and torment Dusk at one point.
