Croire is a pale-tan skinned girl with bright blue eyes and choppy, platinum blonde-white colored hair worn with black ear pieces with red on them. She has a pair of purple and blue gradient themed wings and wears a black dress with silver and red accents, a crimson ribbon tied around her right wrist, and a cape like piece that attaches to her top by the big pink orb in the center of it. With smaller pink orbs below her shoulders.
Croire has a very crass way of speaking and has tomboyish mannerisms to fit her tomboyish look. She uses derogatory terms to describe people rather frequently and definitely hates when people can't get her name right. Croire is shown to have little to no concern about anyone who gets mixed up in her trouble causing because all she cares about is her own entertainment.
Croire decides to bring Neptune to the Heart Dimension. For some reason, there is a lot of share energy in this dimension. It would allow her to bust out of Neptune's Nep-Note. The two meet a girl. She says that she is bored and would like for them to get a console, found only in the basement of the Planeptune Basilicom. Neptune eagerly agrees and Croire has the co-ordinates set so the pair warp off.
Neptune gets the console and asks Croire to teleport her back. Croire tells her that she has ran out of energy. If Neptune wants to teleport, she should let Croire out of the notebook as it drains her energy. Neptune refuses her offer as letting Croire out always causes problems. Neptune then complains about Croire's uselessness which she protests but Neptune ignores.
After leaving the Basilicom, Neptune takes a look at the console. She says there is someone inside the console. Croire finds that crazy and disagrees. Neptune tries to show her more but a portal shows up and sucks the two up.
Zero Dimension Neptunia Z: Twilight of the Desperate CPU
Croire finds a share crystal. She decides to keep it around while looking for something interesting to record in history. She finds Arfoire. After some chatting, Croire finds Arfoire interesting and allies herself with her. Croire is excited about the possibility of recording the end of a world with her. She also mentions that has Rei Ryght's power. The two decide to use the share crystal to lure the group.
The group arrives and Neptune complains to Croire about leaving her. She apologizes and asks Neptune to join her because it is way more interesting than the other group. Neptune declines so Croire says she has been infected with their boredom. She clarifies to the group that she is not their ally and is allied with whatever is interesting. She is impressed that Nepgear remembers her despite Nepgear's horrible treatment in Hyperdimension Neptunia Victory.
Arfoire then finds herself defeated and asks Croire for the Rei Ryghts' power. Croire gives it to her as that will make things interesting. Arfoire gains the power and revives Dark Purple. She then wounds Uzume forcing the group to retreat. She tries to blow them all up with Dark Purple. Croire protests as that will injure her as well. Arfoire does not care. Croire follows Neptune and flees.
As punishment for Croire's earlier actions, Neptune imprisons Croire in her specimen book, the Nep Note with tape so she cannot escape. Croire protests this as she did not know Arfoire was suicidal. Croire has a chance to get out however, if she helps Nepgear and Neptune find "Oratorio's Tangram" and "Jingu Cherry Blossoms", Neptune says she might be let free. Croire says they drop from monsters and wants the girls to gather them as quickly as possible. When they gather everything Neptune retracts her offer. Croire claims she tricked her but Neptune says she only took advantage of her.
Croire and Neptune then go scouting. They notice Arfoire has merged with Dark Purple. The two rush back to the group and update them about that. They have about a day until Arfoire arrives.
The next day, Nepgear lays out the plan. The fused Arfoire is accompanied by a horde of monsters. Nepgear and Neptune are to divert the monster into some ruins when Arfoire passes them. That way Uzume can use her sharing field. Croire wants to be in the sidelines of all this. Neptune brings Croire along in the front-lines as she wants her to record the history of the girls saving the Zero Dimension. Croire demands that her safety be their number one priority.
They try to enact this plan but Arfoire can nullify the share energy. Croire says that should not be possible. Arfoire begs to differ. Umio then arrives with the monsters and a whole bunch of share crystals. However, even that is not enough. Histoire and the small Neptune then offers Planeptune's shares. The two Neptunes encourage Nepgear and Uzume. Nepgear is able to resonate Planeptune shares with Uzume and they create the sharing field. The small Neptune then arrives to take part in the final fight against Arfoire.
The girls then engage in their final fight against Arfoire. They come out victorious and Arfoire's Dark Purple body collapses. The smaller Neptune the notices Croire in her weakened state. She wonders if Croire has learned her listen. Croire says she did nothing wrong, and only recorded the history of the world. Smaller Neptune wonders if she should punish Croire. Croire refuses to be punished by her and flies off. The older Neptune runs off after her. With that Croire was able to record the climatic battle that decided that the Zero Dimension would be saved.
Heart Dimension Neptunia H: Trilogy Finale: Into Legend
Croire revels in her freedom and never wants to see the Nep-Note again. Kurome is happy for Croire. Croire then asks how are the CPUs. Kurome says they are the perfect material for her Dark CPUs. Croire asks her if she is making a Dark CPU using their power as a basis.
Kurome explains that the previous Dark CPU were made imitating the CPUs' abilities. Having the CPU means the Dark CPU can be made by absorbing the CPU's power to perfectly recreate said power. To assist with re-purposing the power, negative energy is added causing the CPUs to eventually fall into delusion. Croire tells Kurome that she is involved in something spooky and heartless. Kurome can't wait until the CPUs actually fall.
Croire and Kurome Ankokuboshi greet the rescue mission. Kurome notes that if she had known older Neptune would have lead them here, she would have killed her earlier. The mission demands the return of the CPUs and Kurome's reason for messing with the Gold Third. Kurome says the purpose of messing with the Gold Third was entertainment because if they fell into delusion, then the world would be chaotic.
Kurome says that it is time to kill the mission. Uzume asks her how she intends to do that as she has Share Energy. Kurome instead asks Uzume to become one with her as they were originally one person. Uzume gets confused so Kurome decides to return all her memories to Uzume. Since, it will take time to process everything, Kurome decides to explain everything. Firstly, CPUs are essentially born from people's wishes. However, for Uzume, her people grew to hate her, they sealed her away then forgot about her. Uzume vowed revenge and just like that, her source of power shifted from Share Energy to Negative Energy generated by negative emotions. Using her delusion power coupled with negative emotions of her people, Uzume deleted all trace of herself from her people.
In turn, the people needed a new CPU, Uranus. Kurome announces that she is a CPU of Planeptune, Uzume Tennouboshi and demands they all kneel to her, increasing the gravity of the place forcing the mission to kneel. Kurome then explains that both the Zero Dimension and Heart Dimension are born from her dream of herself destroying Gamindustri, with the Zero Dimension serving only as an entrance to the Heart Dimension.
This is possible because her power is to turn dreams into reality. This is why Planeptune hated her. Kurome tells the mission that she wanted to break out of the seal, but she could not. However, if her dream created dimensions, she break out of their dimensional boundaries instead of the seal. As she began to attempt this method, a part of Uzume split off from her and tried to stop the Dark CPUs trying to break the boundaries.
But that was good for her, as once Uzume battled the Dark CPU and started to gain Share Energy, she did as well. With the Share Energy, Kurome can observe the Hyper Dimension and appear as a sort of hologram but that was enough. Kurome decided to send Arfoire out to gain even more Share Energy. Kurome then came up with the idea to fuse the dimensions instead breaking out of the boundaries or seal.
Kurome says that the Gold Third are also to thank. The Golden Summits, that were created give a rare signal in multidimensional space. Their existence was thanks to the CPU Shift Period lowering the faith in the goddess, good enough for her to write the CPUs out of existence. Gamindustri, however needed protectors and created the Golden Summits.
Once the dimensions are fused, Kurome can physically materialize the Dark CPUs. Kurome notes that with her Negative Energy, Uzume's Share Energy, Croire's power that came from another CPU, she can rule Gamindustri forever. She asks Uzume to become one with her again. Uzume angrily refuses.
Kurome says it is a shame and will kill her along with the rest of the mission. Kurome creates clones of Arfoire and explains that this is her dream, creating things from her memory is easy. She admits that this gave her quite a bit of trouble in the past but serves as a perfect pawn. The candidates transform ready to fight to rescue their sisters.
Kurome tells them not to get too excited as the CPUs just fell into delusion and she allows them to awaken. The CPUs announce their intentions to torture their sisters and friends and transform. The candidates are pushed back and older Neptune wants to retreat but Nepgear convinces to fight to return the CPUs to their senses.
After the battle, Uzume wonders why the CPUs aren't back yet. The CPUs regain their senses and apologize. Kurome forces more Negative Energy to the CPUs.
The CPUs try their best to resist but are in pain. Kurome tells Uzume that she cannot win. Uzume asks for everyone to pray for the CPUs' return to themselves and she will create a Share Crystal for that. Kurome says it is impossible but Uzume tells her not underestimate her illusion power.
Uzume with the faith of the everyone creates the crystal and transforms the CPUs to their Next Form. Kurome wonders what are those forms? Croire can't believe that they can neutralize all the Negative Energy. Uzume tells her they did not neutralize it but got rid of all of it.
Kurome tells them not to get carried away as she still has Dark CPUs and unleashes Dark Green. Uzume activates her Sharing Field with the Share Crystal. The party destroy Dark Green but find Kurome smiling. Kurome says that she will win and asks them to check the dimensional co-ordinates. Nepgear checks and notices the dimension much closer to the Hyper Dimension but she says it has only been a short time.
Kurome explains it is because they are in the Heart Dimension, she can bring the Heart Dimension closer to the Hyper Dimension with no resistance. She notes that the dimension are close enough for her to materialize, at least for a short time. Croire creates a portal as the two begin to leave to the Hyper Dimension. Kurome leaves clones of the CPUs to buy time. The two leaves.
Heart Dimension route
Croire returns to congratulate the CPUs and group for defeating some many fakes. Older Neptune is surprised to see Croire again. IF asks her what is Croire planning. Croire responds with a question and asks them what are they planning to do after knowing everything.
Noire says they plan to defeat Kurome. Croire reminds them that if they do then the Heart Dimension and Zero Dimension disappear getting rid of Uzume, Umio and all of Zero Dimension's inhabitants. Older Neptune is not happy with the two choices and Croire asks her if she was paying attention. Their choices boil down to letting Kurome do as she pleases which will screw over the Hyper Dimension or stopping her with the consequences that Croire previous talked about.
Older Neptune says Croire is cruel and they cannot choose. Neptune remarks that this must be the part where a third option shows up in a few seconds. Older Neptune agrees and says that the option will likely lead to their happy ending. Croire wonders if the two Neptunes only have games in their head. Well she says they better choose soon as the dimensions are getting closer together.
Umio wonders why must the world being so cruel to Uzume. Croire says it is just Uzume's punishment as she nearly destroyed the Hyper Dimension. Umio wants to know more so Croire reminds him of the strange reports that Nepgear found in the Zero Dimension. Since they were slow on the uptake, Croire decided to repair the data but they never figured it out that the perpetrator was Uzume herself.
Uzume runs away after hearing this. Croire tells the group this and wonders what is their next move. Croire is later ordered by Kurome to guard the Share Crystal in the center of the Heart Dimension. Croire arrives as older Neptune is explain the crystal to the party to add that it is the reason that there are share crystals in the Zero Dimension. Older Neptune is surprised to see her old friend. Croire greets older Neptune.
Older Neptune says if Croire is here then she intends to get in their way. Croire says that is true and complains about Kurome Ankokuboshi being a slave driver. All Croire wants to do is record history but Kurome wants her to defend the crystal. Croire finishes saying if Kurome wants it protected, she should do it herself. Older Neptune asks Croire to stop what she is doing or both dimensions are going to be destroyed. Croire tells her that she should have read her already. She has recorded the beginning and ends of countless worlds already. She cannot record history inside older Neptune's Nep-Note.
Older Neptune understands but the problem she is getting involved in its destruction rather than recording it. Older Neptune says she cannot let Croire stay free any longer. Croire says she thinks older Neptune just wants to use her dimension hopping ability. Older Neptune is shocked that she knows and tries to play that off as untrue. Croire says that she is too obvious and she asks if Neptune was also intentionally sabotaging AffimaX. Older Neptune tries an obvious attempt to feign ignorance. Croire concludes that she has simply been playing the role of the clown the whole time.
Noire says Croire took long enough to figure it out. Neptune may be happy go lucky and spouts nonsensical meta-jokes but she has always been. Neptune cuts her with a scream. Noire and Croire are shocked. Croire tells her to stop yelling as she was not talking to her. Neptune rants about her lack of relevance despite being the protagonist. The party try to calm her down to no avail.
Croire wonders what is wrong with the party but she says they will not get in her way in recording history. Croire summons Dark White. Uzume says Dark White is no match for them due to her Sharing Field. Uzume transforms and activates her sharing field. The party makes short work of Dark White. Blanc laughs as Dark White is dead and says that it serves her right. Croire can't believe the Dark CPUs were so easily beaten. Older Neptune sneaks up to Croire and captures her in her Nep-Note then announces Croire's defeat. Croire demands that she be let out to no avail.
The CPU Candidates and Gold Third rejoin the party in the Heart Dimension base. Nepgear explains that they first lost the console but thanks to everyone's help they got it back. In addition, they were concerned with the Dark CPU but the Share Crystal sorted that out for them. Nepgear wonders how were things with them as they came here because they followed Kurome but she escaped.
IF wonders what she means by follow. Ram says that they though Kurome would use Croire but she ran and eventually they lost sight of her. Noire asks how they can run from the Hyper Dimension all the way here. Uni explains that Kurome broke the rubble that Neptune created and ran here. Older Neptune says it must have been because they captured Croire.
K-Sha wonders what the CPUs were up to while they were all away. Noire explains that after defeating the clones, Uzume got confused but Umio was able to help her clear her head. The hatred Kurome took tainted her memories making them seem worse than the actual events. Uzume and the world never actually hated each other.
An earthquake occurs and Neptune wonders what is happening. Croire says Kurome has finally done it. Older Neptune demands answers. Croire says she has taken in the power of the CPU from another dimension. A fraction of this power can move dimensions with ease but it will likely consume Kurome as Croire told her she should only use after she has revived. Croire remarks as they are all here, she can finally record some interesting history.
Uzume has a plan and they must find her. The party searches for Kurome. The party manages to find Kurome Ankokuboshi in a dungeon. Kurome asks what they plan to do, they kill her, both of them and this world disappears. If they let her go, the dimensions will fuse and she will become the Hyper Dimension. Uzume reveals her plan which is to beat Kurome up and take the power of the CPU from another dimension. If they have the power, they can stop the dimensions from fusing.
Uzume declares that today is the day she defeats herself that is drowning in hatred. Kurome declares that she will defeat herself and all the others in the way. Kurome wanted to have them all alive to experience the eternal hell she was going put Gamindustri through but they are becoming a major interference in her plans. Kurome summons all the Dark CPUs to fuse with them to become Dark Orange. Dark Orange says that the form is perfect for taking revenge on Gamindustri.
Dark Orange calls the party useless as they are unable to fight with Sharing Field. No Sharing Field can contain her. Uzume says she has an ace card and points to the giant Share Crystal in the Heart Dimension. Dark Orange warns her that using the crystal is like using their "lifeline". They will both die. Uzume says she is not suicidal and will use the crystal until there is a little bit of shares left then turn it off. That way, Dark Orange will weaken too.
Dark Orange is angry but calls it useless. Uzume calls this her last HDD and transforms to Orange Heart to activate the Sharing Field. The party manages to defeat Dark Orange.
Dark Orange says that she cannot die yet until her revenge on Gamindustri is complete and performs one last act of vengeance and takes the power of the CPU from another dimension down with her. Nepgear worries about what happen now.
A monster horde is heard. The horde is coming by land, sea and air and are heading towards the Hyper Dimension. Croire explains that she must have given the order to the monsters to destroy the Hyper Dimension just as she died and remarks that she truly went down gun blazin'. The party lacks the manpower and supplies to confront the horde now. They also lack the time to return to the Hyper Dimension to prepare a proper defense. S-Sha admits Kurome has won.
Uzume has one final plan and asks Nepgear to destroy the giant Share Crystal then the party must head back to the Hyper Dimension. Nepgear is unwilling to do so but her sister assists her and the two destroy the giant Share Crystal. The party leaves.
The party heads back to the Hyper Dimension through the portal Histoire created. Umio was able to rescue the monsters from the Zero Dimension as well. The Swirl Console breaks signalling the end of the monster horde and Uzume.
Neptune asks the party if it is okay to leave like this. The party tries to reason with her but Neptune tells the party she needs everyone for a happy ending and runs off for Uzume. Nepgear agrees with her sister's actions and wants to run off. Older Neptune is also unhappy with leaving Uzume. She then realizes that the dimension has not collapsed yet even though the Share Crystal has been destroyed. Uzume must have planned to hold off the monster horde because they would be in big trouble if the horde caught up to them. The dimension will collapse once all her share energy is used up.
S-Sha concludes that if Uzume survives then the Hyper Dimension will have to deal with the horde. Nepgear still wants to save Uzume and runs off. Older Neptune also runs off to save Uzume.
The three girls arrive to help out Uzume. Neptune tells her older self to take care of Uzume and asks her sisters to help her out in holding off the horde. Older Neptune tells Croire to warp them all back. Croire says she cannot as she has no energy. Older Neptune asks her why does she always run out of energy at times like this. Croire reminds her that her notebook constantly sucks away her energy. Older Neptune begins to freak out. Affimojas then arrives with his ship to help the girls out. Affimojas tells them to hurry as their main ship is in the Zero Dimension.
"Croire" derives from the word "Chronicle" and is French for "to believe".
