didn't know that bunny girl senpai was getting another season. the show is pretty good imo, so that's cool.
but most importantly I remember this show for introducing me to my favorite japanese band, the peggies. it's a shame that they split up indefinitely some time ago. I already miss their stuff :P
Last year I think. The lead singer has started a new project called Q.I.S (Queens in Sweaters) with 3 songs out so far, plus she wrote stuff for halca and performed some with Kana Boon. Miku (the drummer) is doing some DJ sets and playing drums with some other bands. The bassist seems to be taking a break for now and hasn't been up to much.
The "Bunny Girl Senpai" is just the title for the first book. The LN series is "Rascal Does Not Dream" followed by whatever the book is about. Like "Knapsack Kid" for this movie. For the anime they just stuck with the title of the first book.
And they do sort of explain it right away when they talk about "puberty syndrome" or whatever it's called. The entire series is about resolving supernatural phenomena happening around different characters.
