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 first appears in the Hyper Dimension after Rei runs out of fear from Neptune and Nepgear and ends up finding herself lost in the city, claiming to have been searching for her for ten days. Fulfilling a request from the Rei of the Ultra Dimension, she force feeds a parcel of dark power into her, which later allowed Rei send Neptune to the Ultra Dimension. She then lets the other Rei know about this development, who meekly informs the other Seven Sages of the development.
Croire appears again in Chapter 5 when Rei had abducted Peashy as a hostage, and starts bullying her. While they were arguing, Peashy began rummaging in Rei's personal affects and tried to eat a CPU Memory core, awakening her as a goddess. Croire is seen again only after the Seven Sages disbanded following Yellow Heart's defeat, who gets incredibly annoyed that she wants to go to the Planeptune Basilicom and turn herself in. With the help of the other Rei, Croire forces Ultra Dimension Rei to regain her CPU powers, whose personality rap[idly unhinges and plots against the goddesses directly.
After the party captures Rei following her defeat, she is taken to the Basilicom for questioning about how she was able to transform. Croire eventually arrives as Rei was about to explain how power was transferred between dimensions. She reveals to have knowledge about Histoire's purpose of creation which is to record the history of the CPUs and weave realities, but doesn't actually disclose her own purpose behind existing other than to "liven up history." She also reveals that unlike Histoire she can't make a connection to other worlds, but she can travel to them. Before she leaves, Croire warns Rei and the others that the Hyperdimension Rei is going to destroy their world right before as the interdimensional assault begins.
During the "Rei's Memories" events, it is shown that Croire has always been with Rei ever since she became a goddess by accidentally eating a CPU Memory, much like when Plutia did the same exact thing and Histoire appeared. Croire explains that since Rei is a CPU that she must form her own nation. When the people begin to revolt against Rei's tyrannical, she ends up destroying her nation (having not realized her power comes from faith). Croire is surprised to see that she is still alive after all that destruction she caused by releasing all of her power at once, and admits to being uncertain as to whether her becoming a goddess was a cosmic mistake.
During the True End Route, Croire observes the fight between the Hyper Dimension Rei and the other goddesses from her "front-row seat." When the Ultra Dimension Rei arrives in an attempt to persuade the other Rei, Croire instead taking the remaining power that she brought over and transfers it to the Hyperdimension Rei so that she can continue fighting. When Purple Heart asks her what her motive is, Croire states that all she wants is to be entertained. After the goddesses successfully take down Rei and get rid of the dark power, Croire leaves the Hyper Dimension in search of somewhere else to stir up trouble.
When she finally arrives at her destination, she is suddenly captured by the Neptune from the Ultradimension with a butterfly net, who mistook her for a rare bug.
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.
"Croire" derives from the word "Chronicle".
