Prologue[]
The game begins with the player riding a boat to Sunbeam Island to deliver a blue orb to Aquilina. However, two pirates emerge from barrels from on board the ship aiming to steal what the player is keeping safe for delivery. After the player begins their first audition, one of the pirates make the protagonist surprised from behind and ends up hitting them on the back of their head.
Thinking that the player was only pretending, the arrogant pirate threaten to toss them off the airship, and the dumb pirate accidentally knocks them off for real.

After Aquilina and her loyal headmaster Otto confirm that they have amnesia, the player is mistaken for a member of the pirate club that being sent to rule Sunbeam Island, and given a house to live in.
Part 1: Red Stone[]
The next morning, one of the islanders, Michelle, wakes up the player and feeds them apple pie before meeting her friend, Chloe, who gives a short tutorial on farming.
The player soon goes back to report to Aquilina, only finding that the real prince of Sunbeam Island, Prince Ferdinand, has just arrived. Aquilina will freak out about her mistake and tries to put blame on the player, but after some explanations are made, Ferdinand tells the latter that he wouldn't mind them helping her out with managing the town. Even if it's against his father's wishes, he against leaving the player out on streets with identity problems. This leads into another tutorial about Invisible Perfume and how to use Princess Ticket.
Upon entering Lagoon Forest for the first time, the player asks some butterflies that seem to lead them deeper into the forest. They later arrive in the middle of the forest, where a little girl appears. Shocked, the player takes the girl to Michael, who looks over her in Clinic. Within four days, she wakes up and introduces herself as Aria, who helps her parents at the chocolatier shop. Talking to Aquilina about her hints that she knows something about the girl, but she does not say anything.
Several days later, the townspeople will begin to talk about screams that can be heard throughout the village. With the player having contributed before, Aquilina asks them a favor to see what is happening. As the player enters Neptuna Ruins, Frey and Bea approach them, telling not to trust "that fool", referring to Aquilina.
After two weeks have gone by, a rumor about the appearance of ghosts near Sunbeam Island, and a girl who appears in the houses and streets of Sunbeam Island seeks out the protagonist for help to save Rambat. Upon being vanished by the Invisible Perfume, a girl named Rebecca moves with her father Javi (NSI) to run the Irish pub.
With the three humans born from mysterious creatures moving into Sunbeam Island, Aquilina collapses, making the player shocked. She tells them a good portion of the story about Michelle, Chloe, Aria, and Frey. However, Frey is against Aquilina's instructions due to her believing that she slaughtered everyone and vows to collect the Sunbeam Crystal before the player does.
Although the Sunbeam Crystals are coming back, Aquilina still asks the player to bring back the final Guardian, Princess Rosie, who resides at Rose Dungeon. However, it is found out that Rose Dungeon has been infused with Watery Forest. After several days of everyone researching, Ferdinand says that he knows of someone who once went to Waterfall Forest, and was trying to get in contact with them. This person turns out to be Gaspard, and he gives the player a homing ring, and a few words that will trigger the ring to allow him/her to return. Despite that, the Homing Ring only works once as the player would be stuck in Waterfall Forest forever if it is messed up.
While going through the path, the player meets twin fox-like girls, Shio and Rio, who are blocking the entrance to the boss chamber. Upon defeating both in audition, the former continue to the final chamber, where a large sarcophagus resides. Shortly afterwards, Aquilina scolds the player for being reckless, so she takes them back to Sunbeam Island by a dolphin. Back on Sunbeam Island, Aquilina restores the Guardian's memories and apologize for what they did to upset her. Life quickly returns to normal and all four live as residents in Sunbeam Island alongside Aquilina.

As the strange man does this, he accidentally reveals that it was really the Dark Moon army who had destroyed his village. He uses the power of Sunbeam Sphere to transform into a dragon, which the player and Serena defeat in audition. Frey reveals that she knows that the Dark Moon gang have a hideout in Bubble Cave, but is not exactly sure where.
Upon finding and infiltrating their hideout, the player is approached by Edmund, Lord of Dark Moon Island, who reveals that he has stolen the Sunbeam Spheres that were placed and using their power to re-create the Native Mermaids. Edmund summons one as a test for the player, and states that even if they do not go after him, he will go after them and townspeople.
It is then when the player feels Aquilina's Charm close to their heart, with the Guardians and Sunbeam Islanders calling out to Player, giving them wishes, power, and desire. The player then receives an immeasurable amount of strength and makes Edmund disappear who goes psychotic and is slowly pulled into Waterfall Forest.
Returning home with Frey and Ferdinand, the town of Sunbeam Island celebrates a party for the safe return of the player and Aquilina. At night, the player talks to Aquilina, who tells them that although her spirit is in the castle, her body is already in the Waterfall Forest.

They describe the situation to the player and wonder what they can do at this point. The player will eventually be forced to choose an option where they suggest using "Orpheus Gate". The four of them get worried because before when the player tried, they nearly stuck themselves in an ensuing explosion. Upon arguing with the player, the four agree to let them use Opus Gate.
The four girls give the player time to prepare, and when ready, the latter talks to Rosie to begin. Upon defeating six rival idols in audition, a short room after every stage gives the player fragments of their Memories back. They later tell Aquilina about using themselves as a Vessel, but upon shouting "Overload!", Aquilina disappears and player is left with a Sunbeam Sphere. At the end, the entire population pay tribute to Aquilina, who has returned. Upon thanking the player for their hard work, they are free to do own activities.
