I couldn't watch the last episode because it seemed like filler.

In the last episode, Luche was suddenly obsessed specifically with going on a date with Elymas. I get that this isn't a huge stretch, but the biggest smell of filler is that characters lose all of their subtlety.

At any rate, I'm sort of watching the end of this season because Luche is interesting. The last episode messed with her character, and this episode didn't have her doing much. I'm losing enthusiasm.

Also, I'm wondering more and more what the target audience is for this anime. When I see a shonen anime of this style, I think maybe it's aimed at 15 year olds. But once I started watching this anime in particular, it starts to be clear that it's aimed at younger, probably around 12 year olds. But Hilde is a cliched character right out of an anime for small children. It's starting to feel like it's aimed at 9-10 year olds, which is too young for me. Maybe this episode was also filler, and so the show can be forgiven, but it involved the main plot, which is usually indicative that it's not filler.
