Okay, putting aside the plot for a while; This episode was really entertaining: Great animation, sounds effects, excellent seiyus, and beautiful execution. I was on the edge of the seats during the whole episode which rarely happens for me :O!
Overall, simply one of the best series I've seen in my life. Some may be disappointed at alto's indecisiveness but to be honest I like how all three became even greater friends (I wouldn't want sheryl or ranka to be left out b/c alto chose one of them). I love the happy ending; no bittersweet ending for me
Episode is full of music <3!!
