On the flip side, I hate how everything seems to be an isekai these days. Feels like a cheap and overused plot point by now.
I would much rather watch an entire series covering the “rising star animator on the verge of burning out” part, than the “she’s spirited away into her favorite childhood anime” part.
The credits list Minoru Shiraishi as the author of the song. I guess Kaorin is a nickname for one of the voice actresses: Kaori Fukuhara.
So maybe just a song made only for lucky star, so he could confess his love for her? 😅
