Story[]

Further explore Planeptune Sea
Inside the Submerged Tower, Blanc notes they can breathe normally here. Neptune sniffs around causing Vert to ask what Neptune what is going on. Neptune says the smell is familiar. Noire also tries sniffing around causing Neptune to snicker. Noire wonders why Neptune is snickering. Neptune thinks Noire is like a dog. Noire gets annoyed with Neptune. Neptune tries to brush it off but Noire stays annoyed. Neptune decides to flee. Noire chases Neptune down.

Explore inside the tower
Further inside the tower, Neptune's party reaches a big door. Neptune realizes this must be the door the girl was talking about. Noire remarks on how big it is. Vert remembers that the girl mentioned the door could not budge but this door is fully open right now. Blanc believes it was forced open by some kind of explosion. Neptune thinks this is lucky for them, so they can go inside as she runs through the door. Noire tries to warn Neptune about how dangerous it can be up ahead but seeing as Neptune already left, Noire and the rest of the party follow her.

Neptune's party runs into Ester Zira and Bombyx Mori. Neptune and Zira are the first to notice each other. This surprises the two of them. Ester Zira struggles to remember Neptune. Blanc notes that Zira is one of Bombyx Mori's Three Musketeers. Zira happily confirms that she is number three of that group. Zira then remembers Neptune the newbie. Neptune wishes Zira does not remember that about her.

Zira reports to Neptune that Arty has been looking for her. She was in the tower earlier looking for Neptune and when she couldn't find her, she left. Neptune notes that was a close call. Zira wonders if Arty would be happy if she captured Neptune for her. Vert agrees that Artura would thrilled if Neptune was captured and given to her. Neptune wonders why Vert would say that. Vert apologizes as she got caught in the moment.

Zira thanks Vert for her participation and declares she will be capturing Neptune now. She prepares her Chocoman No. 1 to attack. Neptune refuses to be caught and draws her sword. Noire tells Neptune not to worry as no one will be getting captured. Neptune declares that Noire is her truest and dearest friend. Noire blushes and tells Neptune to shut up and get ready to fight.

After the party destroys Chocoman No. 1, Zira mourns her destroyed mech. She remarks that she can rebuild it, as they have the technology... Zira brightens up and declares she will be taking her leave now. Neptune tells her not to come back. Zira says that she will capture her later. Bombyx Mori and Ester Zira leaves. Neptune tells her to go away. Neptune catches her breath noting that was close. Noire thinks they should keep going as they are on a mission. Seeing Neptune still, Noire scolds her for just standing there. Neptune whines and appeals to her dearest friend to let her rest a little.

Noire tells Neptune not to call her that and continues to push her to pick up the pace. Vert notes that Neptune and Noire get along so well. Blanc agrees. Noire wonders how those two see that, and tells them to stop it.

The party eventually makes it to the computer room. Noire wonders what is this strange place. Neptune again notes that this place is nostalgic. Blanc sees an information board and reads "Data Storage". Vert sees that most of it is already destroyed. Noire believes that Bombyx Mori is to blame for this. Blanc thinks there could have been information on the lost games in some of these. Neptune remembers back in the archives, that Bombyx Mori declared they were destroying dangerous books.

Blanc begins to get enraged as they destroyed those books because it was just a pain to them. Vert notes that they are destroying all intel related to 3D or VR gaming and that their actions are not forgivable. Noire thinks if they got here earlier, they may have been able to stop them. Blanc declares them unforgivable and Vert agrees. Noire blames Neptune for wanting pudding so much and slowing them down. Blanc and Vert find Neptune unforgivable. Neptune meekly tries to defend herself.

Neptune thinks there is something they missed and tells her party they just half to look. Neptune suggests that there might be a door in the ceiling that is hard to see... Neptune spots that very door. Noire is impressed with Neptune's find and notices that the door is not broken. Neptune suggests that they try opening it and see if they find any info on games. Neptune, however cannot reach the door.

Blanc tells Neptune to leave it to her. Noire wonders what Blanc is doing. Blanc reads a long spell from her book causing the door to open and a ladder to come down. The party is impressed but Neptune notices that the part of the spell that mattered was the "Click" at the end so what was the other party about. Blanc explains to Neptune that the rest was essential. It is ancient spell stuff and Neptune wouldn't understand. Vert recognizes the spell from the novel Blanc was reading.

Blanc tells Vert she is right and it is from the Book of Restoration. The spell just "clicked" with her. Neptune is glad the book came in handy. Since Neptune was the one who found it, she reasons that she in a way was the one who opened the door. Noire agrees to stop Neptune from going on a tangent and the party enters climbs the ladder to the hidden room.

In the hidden room, they see a computer that Noire reads is "to be handled with caution". Neptune thinks it is important so they should grab it. Blanc sees that the cable is severed so they can't turn it on like this. Vert suggests that if they bring it to the Resistance it might be able to be fixed. Neptune declares that they have acquired some treasure. Noire tells Neptune they don't even know if it is treasure yet.

Later, Neptune sees an album. Noire wonders why in album would be in a hidden room like this. Vert wonders whose photos, they are. Blanc thinks they might find out if they look at them. She asks Neptune to open the album. Neptune agrees and opens the album. .

SNRPG-Album

Strange Album...

Looking at the album, Blanc has no idea who they could be. Noire also has no idea. Vert sees that it is just a group of friends playing games together and that they seem very close. Blanc notices that there are 4 game consoles in the pictures. Vert remembers the consoles in that magazine. Neptune notes that if these consoles are in those magazine and Vert does not know them then what sort of consoles are there. Blanc thinks they were the latest tech consoles that were lost. Noire agrees with Blanc's guess.

Neptune points out a photo with Chrome in it. Noire thinks if that is true then Chrome... Blanc says that Chrome knows these people. Neptune thinks part of the mystery is revealed. Vert thinks that the girl next to Chrome in that photo looks like the one that gave them the note to the Mermaid Statue. Neptune agrees with Vert's observation. Blanc thinks the girl looks younger though, having a kid's backpack and everything. Noire says they have to talk to the girl again.

Neptune has one final thing to say. She asks the party if that is okay to say it. Blanc wonders why Neptune is asking that. Neptune says she has noticed something bigger. Noire wonders what Neptune has noticed. She thinks that beautiful purple-haired girl looks like her. Noire, Blanc and Vert bluntly deny Neptune's observation. Noire says that Neptune lacks her nice style. Blanc says Neptune is not as pretty as her. Vert believes that the girl in the picture is smarter than Neptune. Neptune says she did not ask for their opinion. Blanc thinks they should take the album with them for now. Noire agrees, as while it does not unlock any memories for her, it still is a clue. Vert thinks they have to get this to Chrome. Neptune swears that this girl looks like her.

Neptune later finds pudding in the hidden room. Noire tells Neptune not to eat stuff off the ground. Blanc bets that pudding has expired as well. Neptune just wants to try a little taste. Vert tells Neptune she mustn't eat that pudding and that they will eat pudding once they return. Neptune agrees to be patient then. Noire thinks that should be it and they should leave now. Neptune thinks there might be something else here and wonders if they should keep looking.

Search a little longer: 
Neptune thinks they should look around a little more. 
Vert agrees as it is common knowledge to search every
corner of a game. 
Leave: Neptune thinks they have seen enough. Noire 
says they are going now. Neptune agrees.

Neptune declares that they have returned to land. Noire thinks Neptune is always too dramatic. Vert thinks they were able to obtain quite a bit of information. Blanc agrees and thinks there could be even more intel in Planeptune. Noire wants to find that girl from earlier, and suggests they ask some locals. Neptune agrees and that they shoukd get some food while they are at it. Noire ignores Neptune and suggests that they look for houses with lights on. If Neptune chose to search a little longer, she obtains Histoire's Tome VII.
