Funny thing is! I'm looking for answers on this thread because I'm actually studying Japanese and I remember I used to adore this show. So I don't know if the one who opened this thread has the same reason but hey, as long as it helps with one's vocabulary study, it can't be dumb! At least in this context :))
Also, I'd choose Japanese voice actors over some English voice actors any day tbh, even if I didn't understand the language and needed subs. Best wishes!
