I'm enjoying that his fighting style and power draws inspiration and is influenced by Papa Jinwoo, but he has his own unique spin on the power and is making it his own thing. While I would've been happy with just Jinwoo 2.0 doing cool Shadow Monarch things, this new power style could be really interesting.
The power needs to be OP for the sake of the story, but if it isn't interesting then it won't be different from all the SL clones that have popped up over the years. Very interesting....
