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.

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

Mandolin Church Catacombs
Follow the path all the way north and then exit to the east to the Mandolin Church Catacombs: East Section.

Follow the tracks south for a chest containing Score Piece 19. Continue south to enter Ritardando: Secret Hideout. There is a chest containing a Scramasax. You can't equip it now so just hang on to it. Turn around and return to Mandolin Church Catacombs: South Section. Pass the Orange Float and take the west path this time. Follow the path around and then north through the Orange Float to the Mandolin Church Catacombs: North Section. Follow it North and exit for a cutscence.

Mandolin Church Grotto
Go ahead and save and follow the path north until you reach the fork. Head west to get to the chest guarded by a few enemies. It contains a Prophetic Cane, a weapon for Frederic. This is where the six pillars are from the Pirate's Paper 2. Read the messages inscribed on the back of each one. Remember, when you go back to the church you will want to read the lamp on the fourth pew for a letter from Dolce to activate the third battle with her later on. Head back to the fork and go to the east and follow the path around and to the North to enter Mandolin Church Grotto: Middle Section.

To the right near the water, you will find a chest containing another Power Ring. P.S. If you weren't able to get the Cold Medicine earlier then you can back track now and complete that quest.

Follow the path north. You will come to a spot in which the tracks go west across the water or you can follow the path north. Go across the track bridge first for a chest on the left containing a Double Crescent, a weapon for Viola (or a Goddess Bouquet for PS3 version). To the north, battle a few enemies and there is a chest containing a Diamond Clover. Cross the track bridge again and continue along the north path to Mandolin Church Grotto: North Section. Go east for a chest containing a Diamond Clover. Just to the west of the chest some are some tracks that head north. Follow that and head to the northwest corner. Save the game and check your items and item set. Before you continue north, did you search all six pillars earlier and read the messages? If so, continue north for a trigger a cutscene and a boss fight. If not, backtrack.

Root Lurker drops a Herebra.

Tenuto Village
Allegretto has to find Polka. Go west across the bridge for a cutscene with Solfege, Polka's mother. Then continue north to the Flower Field for another cutscene.

Baroque Castle
Now that you have all your players back, you should make sure everyone is equipped properly and get them set up the way you like. After the cutscenes, you begin in the city but you should turn around and enter the castle.

In here, go up the stairs on the left to get to get to Baroque Castle: Second Floor Hallway. Go left and enter Baroque Castle: Guest Room the middle one and play Score Piece 3 for a Rank B and a Poison Whitecap. Play a Score Piece 12 for a Rank A and a EZI Pajamas. Exit the room and continue going left. Enter Baroque Castle: Laboratory.

Investigate the green flask to the left of the chest for a Magatama.

Exit the castle.
