No need for a sequel, considering even after this tournament finishes, this manga would still have had less fights compared to KA. I imagine after this tournament is done and after they deal with any Worm shenanigans during it, if any, we’ll be back to Koga and him climbing up the ranks against the New Generation + promising Purgatory fighters after the merge alongside the Worm and a Tiger’s Vessel plot.
I imagine Mudo actually has some martial arts technique to his fighting style, but that may be too obvious of a contrast against Julius’ pure focus on building up the strength of his muscles alone. If it’s not this, maybe they both are pure power fighters, and it becomes a contrast of how exactly their strength was built up? Possibly Mudo having tougher bones or whatever (I’ve seen that come up in stories, that having strong bones helps with the display of strength; it was a fantasy story, though, so no idea how true to life that is) and Julius has superior muscles?
