I knew nothing about this series and still don't know much about it, but the short drama track (3) kind of helped. Song is obviously a character song and is pretty cute. I like the instrumental rendition on track 2, too. It's surprisingly serious sounding without Momoi's cute vocal. Well, the whole arrangement is different, too, so it's not just the voice that made it sound cute.
Sound quality is surprisingly good. Maybe that's how it goes. Non-mainstream character CD gets less idiot treatment because mainstream basically implies it's targeting the ignorant mass. Since this is not so mainstream, it gets less of that. How sad.
