Tobalt is at least 6"3 with one of the most muscular bodies that Yuuta has ever seen. And he has seen a lot of builds out there since he's one of the professional underground fighters. With his black curly hair that covered most of his face, and with eyes that had the mark of sleep deprivation, Tobalt seemed more like a beast than a normal man. Not only that, the aura he gave off was akin to a ferocious bear who was preparing to attack. And with the countless scars he had all over his body (he was half-naked, and his pants were torn to shreds as if he just came out of a brawl), Yuuta could tell that the adventurer in front of him is a seasoned veteran.
Honestly, Yuuta doesn't even know who Tobalt is until a few seconds ago when he introduced himself. But to him, it seemed like Tobalt is a well known figure in their continent, just like how he is one of the most famous adventurer in their continent.
