This sound like something with high potential.

Kono Oto Tomare!: Sounds of Life

It have been awhile since I watch a music anime, especially the one that focus on being a team in club activity and trying to aim for national level. This is kinda staple for sports / shounen anime, but make no mistake about this anime.
I need to explain that the word "koto" refer to word sound & the instrument focused in this anime (string instrument playing horizontally). Despite the tag the shounen in the anime, this is definitely felt shoujo to me, although the main points of the story is not really romance. It feel like the artstyle, the comedy style as well as several moment encounter that felt shoujo-ish. Anyway, as I mentioned earlier, the premise is about our protagonist who trying to keep his Koto club alive by recruiting new members.
He met 2 person which 1 is violent gangster, but have previous experience with Koto instrument from his grandfather. The second person our protagonist met is the daughter of a well known school who for some reason came to his school instead of joining elite school. The story is mostly revolved about our club members grew throughout the season become a good Koto team for national championship. Just like normal other school anime, they learnt about hardship, struggle, and trying to overcome the challenges.
This one probably might be on boring part as it felt mundane and quite slow at a time. But it have pretty nice synergy between characters that made you wanted to cheer them on to success. At least it quite entertaining, at least when they started to play Koto seriously.
Alternative : Chihayafuru & March came like a Lion are definitely 2 closest feeling i got while watching. Other similar anime is probably Hibike! Euphonium & Your lie in April which both are definitely much more polished anime.

Put my usual paragraph about spin-off of franchise here. Much more unique way to create a spin-off is to combine several franchise into one, which will ensure good amount of references for fan of the anime.
It this anime is good? Depending on how well you know with the series. The animation style is the usual chibi style spin off anime and with only runtime of 11 minute (half of normal anime), so this is just a short anime pretty much. There arent memorable moment in the anime though, pretty much hit / miss depending on the comedy type you enjoy. Again, the logic from their world doesnt apply to other characters.
Strongest parts of the anime is the funny interaction inbetween characters no doubt. This are probably fanfiction wet dream where you see combination from comedy anime, with serious anime, which resulting entertaining show. I also liked the song for both OP & ED, but mostly the ED where it introduced main female from each franchise to sing alone. As for the plot, basically all character from the franchises are teleport into a world where they need to attend to a school and become classmates.
Funny & chaos, this is highly recommend if you at least watched all series. If you didnt, then most of the references will fly over your head. This anime are shorts and swift and played a lot with franchise & high school jokes.
Alternative : 2 anime to my mind immediately. One is Carnival Phantasm and another one is Attack on Titan Highschool. But if you are fan of absurd comedy, then I guess Asobi Asobase & Nichijou are more better quality wise.
