Looks like all the Special Authority hunters have the Rulers Reach skill, so they most likely borrow their powers from Sovereigns. However, the Shadow Sovereign's the only one who completely gave his powers to Jin Woo.
How Jin-Woo's dad's interrogation was handled was so unprofessional. They didn't consider, for example, using Adam White who can speak fluent Korean to speak with him (speaking from behind the glass could be done), but instead sent an S-rank. Fair enough. But then, why the hell hasn't anyone noticed after listening to the recordings afterwards, that that Korean S-ranker was threatening Shin-Woo's dad's kids, and that was the cause of the friction? Or that he obviously has a vendetta against his kids?
Great, another BS poorly designed story arc. This dude had reason to doubt that POS korean hunter's words, but now he is treating them like freakin gospel, and we gotta sit through what 30-40 chapters of a poorly fabricated plotline around that now? this story keeps demonstrating that it CAN get worse than it was.
if you were jin woo, what would you do? he's most likely an enemy of mankind but still your father. Can you kill a person you love to save other people? or instead can you kill innocent people to save someone you love?
