Sound! Euphonium 2 was a great anime but not as good as the first. It sticks a little too close to what worked in season one which is normally fine but the first arc just don't work with Kumiko being the one to solve the problem. Maybe if it was Yuko or Natsuki as they were closer to the incident (and actually involved) it would have been better. I still really liked this season and if you liked season one I think you will too but it wasn't nearly as good.
