Maybe it's both? Like in the latest chapter, Legosi literally grew out his fangs. Like wtf? And it wasn't mentioned that they were already growing, it just sort of happened. So maybe Legosi has regenerative gene, thanks to his grandpa's genetics.
The super fast hair regrowth earlier in the series always confused me. I wonder if it to could be related to his genetics, or it was it was just like a spiritual predator thing
