Invi

Invi is a Keyblade Master who appears in Kingdom Hearts χ. As a Foreteller, she leads the Anguis Union and is an apprentice of Master of Masters.

Before Kingdom Hearts χ
Invi is given a Keyblade forged from her own heart by the Master of Masters, who takes Invi, Aced, Ava, Gula, Ira, and Luxu as his apprentices. Invi eventually achieves the rank of Keyblade Master alongside her fellow apprentices.

After the Master bestows a copy of the Book of Prophecies upon Invi, he grants her leadership over the Anguis Union as its Foreteller. As Invi and the other Foretellers read their copies of the Book of Prophecies, they are shocked by the final entry, which details an event known as the Keyblade War, during which light would expire and the world would reach its end.

When Luxu leaves to fulfill his role assigned to him by the Master, the Foretellers are shocked by his sudden disappearance. Shortly thereafter, the Master meets with Invi alone in the Foretellers' Chamber and assigns her role: to observe her fellow Foretellers. The Master instructs Invi to be impartial in the affairs of the Foretellers in order to act as a mediator. With this, Invi voices her concern over having to form and maintain their own Unions without the Master or Luxu to guide them. The Master informs Invi that change is necessary for things to progress forward and suggests that with her newfound knowledge of the future. Before they part ways, the Master advises Invi to let her heart help guide down the right path, making Invi feel somewhat more at ease.

Invi and her fellow Foretellers are soon introduced the Master's latest creation, the Chirithy. Though the Spirit Chirithy are meant to aid Keyblade wielders in their endeavors, the Master warns them that if a wielder falls to darkness, so will their Chirithy, causing them to transform into a Nightmare.

Without warning, the Master disappears from the world, and although the Foretellers actively seek him out, they are unable to locate him. Upholding the Master's teachings, the Foretellers begin recruiting Keyblade wielders to each of their Unions, utilizing the powers of their copies of the Book of Prophecies in the form of Medals to aid their wielders in collecting Lux in order to maintain the balance of power.

Kingdom Hearts χ[chi]
Having watched the Player defeat countless Heartless throughout Daybreak Town, Invi commends the Player's abilities. Invi offers the Player advice on defeating larger Heartless, suggesting that the Player fight alongside the other Anguis Union members and then leaving the Player to defeat a Darkside. After the Darkside is defeated, Invi reappears and warns the Player that there are others who collect light, but that not all among them share the same goal of bringing peace to the world. Invi allows the Player to discern who walks the path of darkness before she departs.

When Mickey Mouse arrives in Daybreak Town via Star Shard with Chip and Dale in search of Donald and Goofy, he notes that the Star Shard did not guide him there, remaining unaware that Invi is watching him from a nearby rooftop.

The Foretellers take notice of the Keyblade wielders utilizing bangles that, when equipped, provide the power to collect dark energy. Ultimately, the Foretellers decide using the bangles was acceptable for their Union members. Not long afterwards, Ira summons the Foretellers for a meeting in the Foretellers' Chamber, declaring that there is a traitor among them after discovering a Nightmare Chirithy snooping around their home. When Gula proposes to have each of the Foretellers summon their Spirits to prove their innocence, Invi points out that Gula's solution is not viable since it would be easy for any of them to summon a Chirithy that isn't a Nightmare. When Ava proposes that the Nightmare could belong to a wielder in one of their Unions instead one of the Foretellers, Ira brushes this off as unlikely possibility, reasoning that the bangles are the Nightmare's doing and that only one of them could have obtained the bangles, thus the traitor has to be one of the Foretellers. However, Invi voices her disagreement against Ira's claims, citing that there is no evidence to support his theories. After Aced condemns Ira for spreading doubt amongst them, Invi silences him for his disrespect, prompting him to adjure the meeting. Once the other Foretellers left, Invi questions Ira's strange behavior, who then confides in Invi about the existence of the Lost Page, an entry depicting the events surrounding the traitor which has been excluded from the Foretellers' copies of the Book of Prophecies. As Ira believes the traitor is likely whomever is in possession of the Lost Page, Invi begins to wonder if providing the Lost Page to only one of the Foretellers was done intentionally by the Master. Invi then promises to keep an eye on the others, while continuing to report back to Ira.

When Neoshadows appear in Daybreak Town, the Player joins three other Keyblade wielders in their efforts to quash the darkness being spread by the new species of Heartless; however, the Player is the only survivor. After Chirithy witnesses another of his kind fade, Invi appears to speak with the Player, revealing that while the Keyblade wielders are gathering Lux at an amazing rate, the darkness is spreading even faster. With this, Chirithy asks if that means that there really is a traitor among them, to which Invi states that she's not willing to believe that yet.

One night, Player is shown a dream by Chirithy, in which Invi and the other Foretellers meet with the Master in the Foretellers' Chamber, though Nightmare Chirithy quickly puts a stop to this dream.

A few days later, Aced asks to meet with Invi, Ava, and Gula. When Invi arrives, Aced reveals his alliance with Gula and extends his offer of an alliance to her as well - however Invi sees this as a defiant act in pursuit of power, suggesting that Aced has been tainted by Darkness. Conversely, Aced suggests that it is Invi who's been tainted by Darkness, as she reports their actions back to Ira and could for all they know be conspiring with Ira behind their backs. With this, Invi parts ways with his fellow Foretellers.

Invi then reports back to Ira that Aced and Gula have formed an alliance - though Ira assumes this means that Aced is the traitor, Invi argues that Aced's intentions indicate that his Heart still belongs to the Light. Ira points out that Aced is betraying the Master of Master's teachings - which are absolute. As such, Invi volunteers to try and convince Gula to break off his alliance with Aced, believing that Ira's intervention will only make things worse; which Ira accepts. Finally, Invi reveals that Aced has begun to question their relationship, and as such her reports to Ira will be less frequent so that Aced doesn't get the wrong idea.

Following the Dark Corridor Trials, Chirithy ventures to the Foreteller's Chamber to report to Invi. Invi is happy to hear that Player has made such progress, but Chirithy asks if it wasn't a little too early to send Player on such a mission. Invi laments that she has no choice but to hasten Player's training, as he must strengthen their resistance to Darkness as quickly as possible. When Chirithy asks why, Invi reports that the Darkness draws near, and that they will require as many warriors as they can get on the side of Light; which Chirithy shakily accepts.

More than a year after the Master of Masters's disappearance, Invi is successful in convincing Gula that the alliance is pointless, as Aced had yet to rally anyone else to his cause and there had been no incidents since Ira captured the Nightmare Chirithy. Soon after Gula dissolves the alliance, an enraged Aced pursues and attacks Invi; with Invi quickly dodging the attack and summoning her own Keyblade to deflect Aced's next attack. As Invi attempts to escape across the rooftops of Daybreak Town, Aced persistently strikes at her with his Keyblade, forcing Invi to defend herself until he drives her into the ground. Once he has a footing, Aced utilizes magic to draw Invi closer to him - striking at her again and asking why Invi gets in his way. As Aced succeeds in disarming Invi, she tells Aced that he's being conceited, as she is protecting the balance the way the Master of Masters told them to; adding that Aced needs to come to his senses. Moving toward Invi - Aced states that if nothing is done, then Light will expire and they won't be able to avoid the Keyblade War; resolving that they need to defy their teachings to protect the world. Invi asks if Aced is implying that the Master of Masters was wrong, only for Aced to remind her that the Master of Masters isn't here anymore - with Aced claiming that he wouldn't allow his prophecy to come true. Aced once again tries to draw Invi in with magic, but Invi calls him a fool and summons her Keyblade back to her hand. Invi then generates a wall of water to defend herself before propelling through it to attack Aced; who only just manages to guard against her attack. As Aced is pushed thrown back, Ava is guided to the scene by her Chirithy. Gula then calls her over and the two of them join Aced and Invi to inquire about what's going on. Invi accuses Aced of being the traitor, and Gula supports her by summoning his Keyblade against Aced, asking that Ava do the same. Though Ava is hesitant, she reluctantly summons her Keyblade as well. Facing three of his old comrades rallied against him, Aced launches himself into a vicious battle, from which he barely emerges alive.

After Gula reveals himself to be in possession of the Lost Page and accuses Aced of being the traitor, Gula is nearly struck down by Aced - who believes that Gula is in fact the traitor because of this. Intervening, Ava takes Gula into hiding, knowing that Ira is searching for him; with the only one knowing of their location being Invi. However, Invi tells Ira Gula's location - prompting him to confront Ava a few days later. Ava later confronts Invi - asking if Invi had not considered that her actions were actually making things worse that they already are. Invi asks why that should bother Ava, given that she has her own Union and the finest Keyblade wielders from other Unions at her disposal, training them in a secret location. Ava then reveals that this is because that is her role. As Invi had not known, she apologizes to Ava and instead asks what Ira wanted - though Ava truly has no idea, as Ira had just ordered her to give up Gula. With this, Invi asks how Gula is doing - though Ava informs Invi that she's unsure - as Gula is gone, on a mission to collect Lux in order to summon Kingdom Hearts so that he can force the Master of Masters to return and prevent the Keyblade War. This makes sense to Invi, as it explains why Aced and Ira are doing the same - being that they are trying to maintain the balance. However, Invi notes that it wasn't the balance they were expected to keep, because if everyone is collecting Light for themselves then Keyblade wielders would ultimately turn on one another; leading to the Keyblade War. Ava questions what Invi is going to do, with Invi coming to decide that she will collect Lux to in order to maintain the balance no matter what. Invi also suggests that Ava do the same, as they must do whatever they can to delay the Keyblade War for as long as possible.

When the Keyblade War breaks out in the Badlands, Invi leads the Anguis Union into battle. Invi approaches Player after his battle with Aced, apologizing for dragging him into this; though she resolves that she’ll make up for it by making his end quick. After a long battle, both Invi and Player are worn out – with Invi commending Player's Foreteller for having trained such a good wielder. With this, Invi withdraws her Keyblade, telling Player to live on before taking her leave.
