I do like the direction the story has taken overall. But I also like how we got here. If Bearen had been like he is now from the start, I feel like it would've been harder to want to get to know him. The slow descent he's been through has hurt, but it comes from a good place of knowing he has genuine ideals and convictions. It keeps the story feeling like there's real hope for him, especially with the people who haven't even thought about giving up on him. Not just the monster girls, but Fouyo, Sune, his mother, people like that. They might not know just how bad it's been for him, but that's partly on Bearen for shutting them out.
That said, Bearen's drama is the meaty center. If this story was a hamburger, his drama is the patty. But of course, a good burger has things like cheese and lettuce, onions and tomatoes, plus a bun to hold it all together. The monster girls are definitely the other layers, giving more texture and flavor, while what's actually happening in the world, the portals and the other monsters being dumped out of them, is the butter fried bun holding it all together. It's a strong central mystery that enables lots of fun encounters, whether that be another monster girl causing problems for Bearen to solve peacefully as he can, or a pack of monsters that must be put to the sword, it's great for the story.
And it can't be overstated how much fun all the monster girls bring to the story. Ignis' dumbassery rooted in being a weirdo living by herself in the woods, Brynhild's whole thing with what happened to her and how she tried to deal with it, Gorefiend's antics, Miki hitting that cultural divide hard. Illias especially has been a treat this chapter, and I always just liked her being in the background even before. As a character she's got a lot of potential. That Hakutaku from early on especially showed how interesting they can be as antagonists, especially if it's not a contest of strength.
So yes, I'm very happy with the story. The three major components come together to make something greater then the sum of its parts, like any good adventuring party.
