I definitely watched all of HxH 99 at some point, really enjoyed it. Don't really remember it too well, but the show just felt dark , something about the art-style. Really enjoyed it, just can't remember it lol.
Yep. It definitely feels a lot darker. Killua's design is a very subtle change, but one that makes him look really dark and... assassin-y. Hisoka definitely has an even darker character (so far) in this anime. Can't get used to his design yet, though. lol
