It seems to be bad, or at least inefficient, for learning, to listen to something without understanding much. (Above some threshold, perhaps.) So, I put HUNTER x HUNTER (no sub) on hold for now. Also, I still need to catch up on reading manga version Vol.5. (Well, almost catched up.)
Most obvious thing about learning values would be vocabularies and Kanji…
I have another series to watch with JP sub – yurucamp S1. Comparing with かぐや様は告らせたい S3 (also with JP sub), I need to look up less vocab for the former. Anyway, I hope to finish the series, and Kaguya is at Ep.9 (of 13), and yurucamp is at Ep.3 (of 12); so Kaguya seems like a better choice.
