Sorry if this was already answered, but does Varg have any biological enchantments at the start of the series? I'm mostly asking because being able to bearably masturbate twenty times over a 24-hour period sounds like it would require superpowers.

No, he’s all human save for his regular link and intra-skull armor, which is standard for anyone born in UNEGA territory. I don’t think it requires superpowers, just a can-do attitude and some free time.
