Koisuru Asteroid resembles Yama no Susume quite a bit in structure, just focused on geology and astronomy instead of mountain climbing. Though primarily an educational schoolgirl club comedy it also features a not insignificant number of dramatic subplots (usually relationship-related) that crop up periodically, the appearance of which are usually as much of a surprise to the show’s characters as the viewer.
While also focused on comedy, Isekai Maou features a pretty much equal amount of action and drama as well. This is a series I’ve been on the fence about pretty much since it was first announced due to its synopsis bringing to mind Shinmai Maou no Testament (which did not handle its erotic elements well), but turns out it’s more like a combination of Overlord and Hagure Yuusha. It’s shockingly well made for an isekai harem series, although the ecchi content certainly does veer into overwhelming/awkward/creepy territory more often then I’d prefer.
Speaking of comedies: I recently tried watching Nami yo Kiitekure… only to lose interest pretty quickly about halfway through the first episode. It was just overly weird. Setup, characters; all weird.
