I love this shit so much.
Frankly speaking, I'm not a big fan of fan-service focus animes, too in your face and too awkward for me.
But I still can enjoy it if it comes with good comedy, and this series does a great job at that, sure there is "lore" and "action" but it never takes itself too seriously and there are no annoying characters, most importantly I think the mc is one of the best neutral mc as you can get
