Eternal Sonata/Chapter 5: Nocturne

Ritardando
You begin in Ritardando: Secret Hideout with Allegretto, Beat, and Frederic. Re-fill your item set from your fight with Fugue and save your game.

Go up the ladder to get to Ritardando: Underground Passage and then the other ladder to the west to get to Ritardando. Play Score Piece 1 with the boy near the fountain for a Rank B and a Star Cookie and play Score Piece 3 for a Rank A and a Cherry EZI. Head to Ritardando: Bakery for two score pieces: Score Piece 17 and Score Piece 18. One is west of the table and the other is in the back east corner. Then go north east for a cutscene around the church. Now, you have met up with March, Salsa, and Viola. The gang is going to take care of the church dilemma while Allegretto goes to find Polka.

Take Allegretto down to the beach for another cutscene.

Now you are in control of Beat and the rest of the gang as they help the good people of Ritardando with the noises under the Ritardando: Mandolin Church. Rearrange your players so you have who you like. This is the first time you have access to March. Make sure you attach some accessories to March and give Viola the Thunder Stir that you got earlier. Before you investigate the problem, you should do a few more things. Exit the church and return to Ritardando.

Return to the area near the hideout and Sym will stop you for another cutscene. Apparently, one of the kids from the sewers is sick.

Ritardando Sewers
You won't find the medicine in here so just head back to Ritardando. You should know the way. Don't worry about fighting the rats cause they won't give you much experience. All of the chests have been opened to so don't bother.

Ritardando
Head to the Ritardando: Pharmacy which is the building near your hideout. They're sold out, so head over to Ritardando: Residence across the way. You will need the Power Ring for this so if you have it equipped take a moment to unequip it. Go ahead and trade her the ring for the Cold Medicine

Head to the sewers.

Ritardando Sewers
Take the Cold Medicine back to the children. Again, you should the know the way. In return, they will give you a Spell Book.

Exit the sewers.

Ritardando
Of course, you can't visit Ritardando without visiting the Ritardando: Item Shop. Beat needs a new Hatchet Musket and a Battle Shirt and a Leather Guard for Polka. If you missed anything else, along the way you can buy something else to max everyone up but you should be good.

Now visit Ritardando: Mandolin Church. Make sure to talk with the Priest to heal all party members before you go down below. Enter the double doors.
