I was waiting for the scummy or useless shoe to drop on this new guy, but so far...he's not bad. His enthusiasm is totally gonna be necessary to keep the party going since Abel is pretty low-key and passive for the most part.
The fact that he's willing to act as bait to protect his new party (in a motherf*cking Jojo's reference) is a big plus too. I'd still like to confirm why his party broke up to begin with, but I'm totally into him being part of the team.
...Also, having another dude in what will most likely eventually be a harem story is just...yes please.
