Seto Kaiba

Seto is the main protagonist for the Millennium Hearts series, as well as a former Keyblade wielder and Princess of Heart. She is a mature teenage angel who has a high level of intelligence and is hard-working, a strong sense of justice as Sora does, and a kind and unrelenting heart. At times, she is impulsive and quick to anger when defending her friends, but she is always sincere about what she says and does. She has been best friends with Tea and Joey since their early childhood.

Seto is eight during Millennium Hearts Birth by Sleep, eighteen years old at the beginning of Millennium Hearts and Millennium Hearts: Chain of Memories, nineteen (mentally) during the events of Millennium Hearts II, and twenty to twenty-one years old (mentally) in Millennium Hearts Adventures. She lives in Domino City with her younger brother Mokuba, her cousin Atem, her childhood friends Tea' and Joey, and their friends and is the second-best champion of Duel Monsters and a successful Idol. Seto is also the original persona of  Xaibak, the source of Adena's memories, and the carrier of a piece of Melody's heart. Seto's name technically means 'seahorse' and was named after Red XIII's grandfather. Her full name technically translates to **a high-bridged, kind-hearted seahorse.**

## *Quotes*

*"I won't let anyone use me anymore! I am my person!

And it will have a happy ending!"-Seto when she faces Incubus.*

*“The Pharaoh, Awai, and I are looking for the ones we care about, my brother, his Hikari and friends, and her best friends. They’re looking for a person that doesn’t seem to want to be found if he left on his own. You’re not a horrible friend as that idiot put it. You just realize what I’m saying before you even notice it.”*-Seto cheering Sora up.

*“It gives some people hope that...even if the ones they lost is a little bit like you, then they made it through the Darkness.”* - Seto telling Sora not to give up.

## Story

### Millennium Hearts Birth by Sleep

Seto, Tea' and Joey are shown as best friends as they grew up.

Sometime before Millennium Hearts Birth by Sleep, Seto's newly born heart encounters the ill heart of Melody and mends it, offering to help her restore her sick heart until help is not needed. This allows them to form a connection with one another and causes Xaibak's face to resemble Melody's.

By the time Seto is eight years old, she encounters Melody, Terra, and Aqua, three Keyblade wielders of the generation before her, on separate occasions. She never spoke with Terra or Ventus, but they have seen each other on Purity Islands. Terra shows no interest in Seto because he is unable to sense her potential. Aqua recognizes their friendship as hers to Terra's and tells Seto to protect her friends if they were to fall into the hands of darkness, to which she agrees. Melody speaks with Seto and places a spell on her. If Melody would ever die, Seto would become the next Eighth Princess of Heart. Materia had visited the islands multiple times but had never met Seto face to face.

Near the ending of Millennium Hearts Birth by Sleep, Seto and her mother rest on a beach. When they prepare to go home, Seto suddenly feels sad and sheds a single tear. Her mother tells her that perhaps someone from another world is sad somewhere and tells her to try to reach them. Seto closes her eyes and reaches out, which results in her being sent to the Awakening and encountering a piece of Melody's shattered heart. It had lost its path and must return to slumber, though it is reluctant to do so and asks if it could become a part of Seto's heart. Seto accepts the request saying that as long as she can make it happy by doing so, she is willing to.

### Millennium Hearts

One year after the events of Millennium Hearts Birth by Sleep, a mysterious young girl named Teha came to their city from a different place. She was adopted by Maximillion Pegasus, and Seto and Mokuba quickly became friends with her. Another day, Seto and Luka found a small, hidden cave on their former islands. They search the "Secret Place" while discussing Teha and the meteor shower that had recently fallen. They find a door with no handle at the back of the cave and because they couldn't open it, they leave, but not before Luka sees the world's Keyhole.

Seto dozes off at work and has an odd dream where she travels through an odd, dark realm with Atem and battles a massive dark creature. However, the night before they set sail, a storm ravages the island along with a strange, dark force. Luka and Teha succumb to the force, claiming they are not afraid of the darkness it so clearly embodied, while Seto and Atem try and fail to save her sister and friends from the darkness.

However, it is during the tempest that Seto first unlocks her potential as a Keyblade wielder, summoning the power of the Heart of Gold to battle the Heartless that now infested their home. She makes her way to the Secret Place where she finds Joey, who disappears when their bodies meet, forcing Seto and Atem to battle the same dark creature from their ‘dream’. Seto and Atem defeat the monster, but they are swept off the island/city and thrown into a Corridor of Darkness, which lands them in a world called Traverse Town.

In Traverse Town, Seto and Atem meet Sora, Donald Duck, Awai Hashiba and Goofy, the Keyblade Master, respective Royal Court Magician, veteran Keyblade Bearer, and Captain of the Royal Guard of Disney Castle. Under orders from The King and The Countess, they are searching for three things: a mysterious 'key', a ‘maiden with a pure heart', and a man called Leon. As the King and Countess have disappeared in their quest, Sora and Awai accompany Seto and Atem and they start searching for their respective friends. In addition to that, Seto finds that she might perhaps be the mysterious ‘pure heart’ the King and Countess had asked them to find.

Upon reaching Hollow Bastion, Riku and Luka confront Sora and Seto and reveal to them that Riku and Luka themselves were the true Keyblade masters, explaining that Sora "was just the delivery boy" and Seto "was just a lowly songstress". Riku and Luka then claim their Keyblades for their own. Despite their guilt at doing so, Donald and Goofy are forced to abandon Sora and the others because of the King's and Countess's orders: to stay with whoever has the Keyblades. When Beast pulls himself up to continue to the castle, Seto tells him to be careful due to his injuries. However, Beast shrugs off Seto's worries, saying that he would not leave before he completed what he'd come there for; to find Belle. When asked what they came for, Sora and the others realized that they need to show the same attitude as the Beast, and continue with him into the entrance hall of the castle.

There Sora and the others meet Riku, Goofy, and Donald once more. But for some reason, Luka wasn't with them. Feeling guilty, Donald and Goofy return to Sora's side. Riku then asks Sora, "How do you intend to fight without a weapon?" to which Sora answers, "I don't need the Keyblade. I've got a better weapon. My heart!". Riku taunts Sora, calling his heart pathetic and weak. Sora proceeds to tell him that his friends strengthen his heart. At this, the Keyblades realize that Riku has turned to darkness, and Sora's and Seto's hearts are far stronger than Riku's, so they return to Sora and Seto. Enraged, Riku fights Sora and loses. Seto asks where Luka is, and all he says is: "She's getting ready for her wedding." Remembering the Ansem Report she found at the Shadow Domino City, she runs ahead to find her. Riku, furious at his weakness, makes the mistake of listening to a mysterious man. Opening his heart fully to darkness, he allows himself to be possessed by this man.

After this, the party encounters Maleficent and defeat her. Using a Keyblade born of six of the Princesses of Hearts' hearts, Riku unlocks the darkness in her heart before stepping away through a Corridor of Darkness. She transforms into a black, fire-breathing dragon from the proliferation of darkness in her heart, but is again defeated, and the Heartless swallow her heart. Realizing that Mokuba's heart was dormant in hers, she uses her Keyblade to set him free, falling into a comatose state, leaving Atem with these words: "Take care of Mokuba for me.", unknowingly creating Xaibak and Joxy, the Nobodies of Seto and Mokuba respectively. Further, into the depths of Hollow Bastion, Sora encounters Riku once more, and he calls himself "Ansem, Seeker of Darkness", who intends to find Kingdom Hearts itself. Beside him was Luka, who Ansem called his "Heartless Bride". Although it is difficult fighting his best friend and Seto's 'older sister', Sora emerges victorious in the struggle.

Kairi is revealed to be one of the Seven Princesses of Heart who possess the power to open the Final Keyhole that leads to Kingdom Hearts, but because her heart laid within Sora, it cannot open, as explained by "Ansem". To return her heart and wake both her and Seto up, Sora uses the Keyblade of People's Hearts to remove both their hearts, sacrificing his humanity and becoming a Heartless, unknowingly creating Roxas and Naminé, the Nobodies of Sora and Kairi respectively. When he manages to reunite with Kairi and Seto after a brief stint as a Heartless, Kairi uses her light to restore his human form.

After regrouping in Traverse Town, Sora and Seto decide to return to Hollow Bastion to seal the Final Keyhole while they try to reclaim Riku and Luka from the clutches of "Ansem". Mokuba gives Seto his DM locket (Dragon Heart's keychain) since she insists that he should stay behind, even joking that he would be in her way.

Sora, Donald, Goofy, Seto, Atem, and Awai set sail to Hollow Bastion and seal the Final Keyhole after a battle with a powerful Heartless. The six Princesses of Heart then inform him of new darkness approaching, and the six travel to End of the World, the "Heartless world" of all the worlds that fell into darkness, where they confront and defeat "Ansem" once and for all. "Ansem", defeated, calls forth to Kingdom Hearts to fill him with the power of darkness, but Seto proclaims that Kingdom Hearts is not darkness, but light, and "Ansem" is destroyed by the said light.

However, Heartless begins to swarm inside of the door, and Sora, Donald, Goofy, Seto, Atem, and Awai rush forward to close it. As they attempt to close the Door to Darkness, Riku, Luka, Nafrini and King Mickey appear on the other side of the door, and together, King Mickey, Nafrini, Seto, and Sora seal it from both sides with Sora's and Seto's Keyblades from the Realm of light and Mickey's and Nafrini's Keyblades from the Realm of Darkness. However, Mickey, Nafrini, Luka, and Riku become trapped behind the door as it closed shut. Riku's last words to Sora and Seto before it closed are "Take care of them", referring to Kairi and Mokuba.

As the worlds begin to restore themselves, Seto sees Mokuba on a platform of sand that is drifting away. Mokuba and Seto are separated with Mokuba going back to Purity Islands/Domino City. Seto promises to return to him as soon as she finds Riku, Luka, Nafrini, and King Mickey.

### Millennium Hearts: Chain of Memories

After being separated from his friends, Sora, Seto, and Atem wander down on a long, meandering path with Donald, Awai, and Goofy searching for a way to find Riku, Luka, Nafrini, and Mickey, encountering Pluto on the way. When they reach a crossroad and call it a night, a mysterious man in a long black hooded cloak appears and informs Seto, "Along the road ahead lies something you need. However, to claim it you must lose something dear to you". The man disappears and only one path remains. The six follow the path which leads them to a mysterious castle known as Castle Oblivion. They enter the castle hoping to pick up some clues as to the whereabouts of their friends only to discover, as they ascend the floors of the fortress, they are beginning to lose their memories and become more and more uncertain of what they are truly after. Even Jiminy's journal has been erased of its entries.

Little do they know, their memories are being manipulated by a mysterious organization that seeks to capture and manipulate Sora and Seto. To do this, they use Naminé and Joxy, young "witches" who could rearrange the chains of memories in a people's minds and create new links between them. To make Sora and Seto forget Kairi and Mokuba, Naminé and Joxy begin to replace their memories of Kairi and Mokuba with themselves, partly because they are Kairi's and Mokuba's Nobodies and so are unable to completely erase them from Sora's and Seto's memories. Meanwhile, a conflict between the members of the Organization leads to several encounters between Sora and Seto and Riku and Luka, whose memories of Kairi and Mokuba and Ansem have also been replaced with ones containing Naminé and Joxy.

The six heroes' uncertainty builds up to a point where they end up in Twilight Town, a place that Sora and Seto are fairly certain that they have never been in, and thus should not exist in their memories. Organization member IV, Vexen, reveals that it is a place that exists on the other side of Sora's and Seto's hearts, but is eliminated by Axel, another member of the Organization before he can explain anything. His 'Life Essence' is absorbed into the Memory Crystal that he gives to Seto before fading away, allowing her to borrow his power when needed.

Axel ends up betraying Marluxia, the lord of Castle Oblivion, revealing that Marluxia and Larxene, the newest members of their group, intend to use Sora and Seto to overthrow the Organization. Axel manipulates Naminé and Joxy into doing what they believe is right. Donald, Awai, Atem, and Goofy try to reason with Sora and Seto about the whole situation later, but they are so stubborn that they separate from them to go on their own.

On Purity Islands, Seto is touched to have finally found Joxy, who tries to make her remember who was truly important to her. After taking one look at the DM locket, it returns to its original form and Joxy takes on the temporary form of Mokuba. Seto and Sora escape the memory-based Destiny Islands and Purity Islands and confront Naminé and Joxy, who reveal that they never existed in Sora's and Seto's memories and that they have been replacing the people most important to them. Riku and Luka appear to them again and are again defeated by Sora and Seto. When Sora and Seto try to help the injured Riku and Luka, they attack Sora and Seto and gain the upper hand. Having left no choice, Naminé and Joxy use their power to break Riku's and Luka's memories, and it causes both of them to collapse. Larxene comes forth to eliminate Sora, Seto, Luka, and Riku, who are revealed to be a Riku Replica and Luka Replica, created by Vexen.

When Larxene is about to eliminate Sora and Seto, Donald, Awai, Atem, and Goofy catch up to save them. Although Sora and Seto had been jerks to go on their own, they quickly forgive them and state how they would always stay together. Together, they defeat Larxene's Dark Silhouette and Sora and Seto forgive a regretful Naminé and Joxy for their actions. They promise to restore the memories of the six once they reach the 13th Floor of Castle Oblivion, where Marluxia is waiting for them. Axel attempts to destroy Marluxia himself, but then Marluxia uses Naminé and Joxy as human shields. Sora and Seto step in and defeat Axel. After finally catching up to them, Marluxia orders Naminé and Joxy to completely erase Sora's and Seto's memories so he could make Sora and Seto his puppets; Naminé and Joxy refuse, but Sora and Seto order them to do so to protect them from Marluxia's wrath. Fortunately, the Riku Replica and the Luka Replica, their true memories returned after their false ones are broken, arrive, and save Naminé and Joxy before they were able to do so.

Then Sora, Donald, Goofy, Seto, Atem, and Awai step into the thirteenth floor's dimension where they fight Marluxia in an incredible battle. Marluxia reaches out to Seto for her to save him. Because she had seen Vexen’s memories, she saves Marluxia and fuses his Life Essence with her’s.

Once Marluxia was defeated, Naminé and Joxy ask that they step into Memory Pods that would rearrange their memories back to the way they were at the cost of breaking the links they created. They also inform them that the process will take some time, during which Sora, Donald, Goofy, Seto, Atem, and Awai would sleep as their memories are slowly restored. While they know that they would forget Naminé and Joxy, Sora and Seto promise them that while they were forgotten, they would remain somewhere in their hearts, never lost. And when they wake up, they would become friends for real.

Right before they went to sleep, Naminé and Joxy inform them that some of their memories are unreachable and asks them to remember Kairi and Mokuba, because their memories of them are the lights that would bring them all back. Sora and Seto then use most of the power of their memories to remember Kairi and Mokuba before going to sleep for real.

### Millennium Hearts 358/2 Days

Naminé's and Joxy's powers are unable to do much to fix the problems, however, recovery becomes more apparent as they discover the existence of Roxas and Xaibak, Sora's and Seto's Nobodies, Adena, a Replica that used to belong to a dark organization, and Xion, a replica of Roxas created from Sora's leaked memories. As Roxas and Xaibak and Sora and Seto are connected, and Xion and Adena are created from their intertwined memories, Sora's and Seto's lost memory pieces found their way inside Xion and Adena through Roxas and Xaibak. This act causes Sora's and Seto's memory restoration process to come to a complete stop.

The Organization intends to have Xion and Adena absorb Roxas and Xaibak, forming a "new Sora" and "new Seto" under their control, an act that would erase Roxas and Xaibak and make it impossible for the real Sora and Seto to ever awaken. When Xion and Adena discover this truth, they are willing to instead return to Sora and Seto, saving them at the cost of their existence.

But before they can, Axel and Xeal, Axel's own Replica, come to take them back to Organization XIII, starting a fight which Xion and Adena lose. During their captivity, they are stored within machine-like devices and given new powers so they may be able to absorb Roxas and Xaibak when the time comes.

Eventually, Xaibak and Adena meet on the Clock Tower at Castle of Dreams, where she removes her hood, revealing that she now completely resembles Seto through the effects of her memory flow. Although she fights with all her strength, Xaibak defeats her in the end, and as she disappears and returns to her origin she asks Xaibak to free the other members from "his" control.

Although Seto's lost memories are back where they should be, Xaibak, Seto's body, and soul are still on the loose, preventing Seto's complete restoration. Riku and Luka hunt Roxas and Xaibak down and find them just as both teams arrive at Memory's Skyscraper, Roxas and Xaibak having defected from the Organization. After an intense battle, Riku and Luka capture Roxas and Xaibak and bring them back to DiZ, Naminé, and Joxy.

### Millennium Hearts II

One year later, Sora, Donald, Goofy, Seto, Atem, and Awai awake in the basement of the Old Mansion located in Twilight Town with their former memories restored, although they cannot remember what happened in Castle Oblivion. But before they awake in Twilight Town, Roxas and Xaibak come to see Sora and Seto and eventually fuse with them. Continuing their journey to find Riku, Luka, Nafrini, and King Mickey, they set out traveling across new worlds, meeting old friends and enemies from the original Millennium Hearts movie while also making new friends. They continue the battle against the Heartless and now a new threat, the remaining members of the Organization they encountered in Chain of Memories.

Soon after exploring Twilight Town, Sora and company head off to the Mysterious Tower, and Sora and Seto obtain new attire—on the advice of master sorcerer Yen Sid considering Sora's and Seto's first outfits to be "too small"—from Flora, Fauna, and Merryweather. The new outfit enables Sora and Seto to transform into their Drive Forms and attain special powers for each of them. The source of the clothing's magic is linked to Sora's and Seto's hearts, which are connected to everyone Sora and Seto had befriended including Donald, Awai, Atem, and Goofy. Sora and Seto were referred to as the "Keys that connect everything" by Yen Sid which is how Naminé's and Joxy's memory manipulations work. Before Seto leaves with the others, Yen Sid tells her that because her world is not connected to the others, she, Atem, and their friends have to forget Sora and his friends and they will have to as well. Seto says she understands but still feels sad inside.

Sora and Seto express their determination to bring Riku and Luka back home with them to Destiny Islands and Purity Islands, where Kairi and Mokuba are waiting for them both. The quest gets more complicated when Kairi and Mokuba themselves get kidnapped by Axel. Pete (who works for the resurrected Maleficent) and Organization XIII are causing trouble in the other worlds, and King Mickey and Nafrini refuse to give information regarding Riku and Luka. Sora and Seto must also discover why some of the members of Organization XIII address them as Roxas and Xaibak even after they clearly state their names are Sora and Seto. They travel to other worlds to find Riku, Luka, Nafrini, and the King, help the worlds and stop Organization XIII. Their new journey brings them to meet up with some old friends and make new ones.

At one point in the storyline, Donald and Goofy's homeworld becomes infested with Heartless, which is rather unusual considering their world's protection, and Sora, Atem, Seto, and Awai visit their castle for the first time. While Donald, Goofy, Atem, and Awai set out to warn the castle's residents about the danger, Sora, Seto, and a young woman named Xnowflake escort Queen Minnie to the audience chamber where the Cornerstone of Light is hidden under. She finds out that Pete and Maleficent have found a doorway to Timeless River, a past timeline of their world before the castle was built. With some help from Merlin, Sora, Donald, Awai, Seto, Atem, and Goofy travel through time and manage to stop Pete from destroying the Cornerstone of Light in the past, which also saves the castle for good.

Sora and Seto, with the help of the Hayner, Pence, Olette, and Vera (four friends of Roxas and Xaibak in DiZ's simulated Twilight Town), and Axel (who sacrifices his existence), manages to find the route to the World That Never Was: which is the stronghold of the Organization, where Kingdom Hearts, created by gathering the countless hearts from the Heartless slain by all of the key bearers, resides. Soon after entering the world, however, in the area of Memory's Skyscraper, Sora's group is ambushed by Samurai Nobodies and Sora and Seto are forced into a showdown with two Organization members, who turn out to be Roxas and Xaibak (disguised in their former Organization XIII cloaks) on two different platforms of the Awakening.

At the start of the fight, Sora and Seto ask who Roxas and Xaibak are, and they answer "Someone from the dark.", then ask Sora and Seto: "Tell me...tell me why he/she picked you!".

As Roxas and Xaibak are above and Sora and Seto below, they see the pictures of Riku, Luka, Kairi, Mokuba, Donald, Awai, Goofy, and Atem (as the platform's designs). Roxas and Xaibak then say, "I see, that's why.", and continue the fight. Roxas and Xaibak knock the Keyblades out of Sora's and Seto's grasps, and as they go to retrieve them, Roxas and Xaibak pin them down with their Keyblades. Sora and Seto then reach out for their Keyblades, which disappear and reappear in their hands, after which Sora and Seto quickly strike while Roxas and Xaibak stand shocked, not knowing how that happened.

Ultimately, Sora's and Seto's control over their Keyblades gave them the edge over Roxas and Xaibak, who collapse and reveal their faces. As they and the scenery disappear, Roxas and Xaibak say to Sora and Seto "You make a good other." Sora and Seto reappear next to Donald, Awai, Atem, and Goofy, who tell them that while they disappeared, they had to fight some Nobodies, and they continue towards the massive castle where Kairi and Mokuba await them.

Afterward, Sora, Seto, Donald, Awai, Atem, Goofy, Nafrini, and King Mickey storm the Castle in search of their friends. They meet Saïx at the Hall of Empty Melodies, who tells that Kingdom Hearts is near completion, and it only needed "one more dose from the Keyblade Bearers." He summons hordes of Shadows and disappears to go after Maleficent and Pete who were also in the castle. The Heartless overpower Sora and Seto but are destroyed by a rain of laser bullets. Sora then engages in a battle with Xigbar and soon defeats him. Demyx appears in solid form and tries to break the memory spell that was put on him. Xigbar then remembers Demyx and the Dark Silhouette is destroyed. They find Kairi, Mokuba, and Luka, and Riku (with the appearance of Ansem, Seeker of Darkness, and Cerela, her dark Persona, which is the price they paid to help Sora and Seto wake up).

Sora, Seto, Riku, Luka, Kairi, Mokuba, Donald, Awai, Atem, and Goofy make it to the Proof of Existence of the Organization, in which there are only two places to go. They enter one of the odd pathways only to encounter Luxord. Although Luxord traps everyone but Sora and Seto in cards, he is enraged at what she did. Thinking that she was the one who had turned him into a Nobody, Xigbar appears and stops him from hurting her. He tells Luxord to fight 'his' control. As much as Seto didn't want to, she defeated him and reversed the damage done to his memory, losing him in the process. Next, they enter Addled Impasse where they find Saïx staring up at the moon. Saïx points out that only Roxas and Xaibak could have made it this far in one piece and Sora gets angry and prepares to attack him. Saïx blows Riku, Luka, Mokuba, and Kairi away and uses the power of the moon to fight. After one of Sora's most difficult battles, Saïx is finally defeated. Sora and Seto then question who Roxas and Xaibak are and why they were constantly being called by those names when Riku and Luka finally reveal to Sora and Seto that Roxas and Xaibak are their Nobodies.

With the mysteries of Roxas's and Xaibak's identities finally solved, they continue. Fighting their way up the winding paths of the Castle That Never Was, Sora, Seto, Riku, Luka, and the others encounter King Mickey, Nafrini and DiZ, now revealed to be the former ruler of Radiant Garden before it was taken over and renamed Hollow Bastion, Ansem the Wise, who was trying to absorb Kingdom Hearts into his machine and encode it as data. Xemnas appears to see who is tampering with Kingdom Hearts and finds his old teacher. Then Xemnas finally tells Sora and the others of his true plan, to make a Kingdom out of hearts. One that he would rule.

Unfortunately, Kingdom Hearts proved too strong for Ansem's machine, and with his final words, he tells Sora and Seto the rest is up to them and tells Roxas and Xaibak, "Roxas, Xaibak, I doubt you two can hear me but, I am sorry", before the machine explodes, taking Ansem with it. The energy released in the explosion destroys a good deal of Kingdom Hearts and reverts Riku's and Luka's appearances to the way they were.

Near the pinnacle of the castle, Heartless appear in vast hordes. Maleficent and Pete show up and stall them while the party heads toward their final battle. When they reach the Altar of Naught at the pinnacle of the castle, they confront Xemnas, the leader of Organization XIII. After a short conversation with the Nobody, Sora and Seto are taken by Xemnas to the front of Memory's Skyscraper for a one-on-one battle. After an intense fight, Sora and Seto defeat Xemnas and are transported back to their friends.

However, Xemnas appears again and, despite the protests of the group, enters and absorbs Kingdom Hearts. The party was in luck though, and by the will of the worlds, a door to Kingdom Hearts is made. Sora, Seto, Riku, Luka, Nafrini, and the King open the door with their Keyblades, breaking the barrier separating them from Xemnas. The party enters but Sora, Seto, Riku, Luka, Donald, Awai, Atem, and Goofy become separated from King Mickey, Nafrini, Mokuba, and Kairi because of Xemnas.

Inside, they discover that Kingdom Hearts was made by the Superior to look like the World That Never Was. They charge through and quickly get to Xemnas and battle him, with Xemnas in armor using the tactics of the rest of the Organization. After they seemingly defeat the Organization leader and return to the Altar of Naught, Roxas and Xaibak emerge from Sora's and Seto's bodies to speak with Naminé and Joxy before they fuse with Kairi and Mokuba. Before this, Naminé and Joxy open a door to lead them out of the World That Never Was. They inform Sora and Seto that whenever they and Kairi and Mokuba are together, Roxas and Naminé and Xaibak and Joxy will be together as well. Naminé and Joxy then join with Kairi and Mokuba to complete themselves, while Roxas and Xaibak return to Sora's and Seto's bodies making Sora and Seto whole.

Unfortunately, before Sora, Seto, Luka, and Riku can enter the Corridor, Xemnas attacks once again on the Captain's Seat of an enormous Dragon Nobody. In an epic air battle, they manage to defeat this form of Xemnas as well. Riku is injured by Xemnas, who strikes at the four of them with his Ethereal Blades. Falling through the air on the brink of defeat, Sora grabs Riku's Keyblade and batters Xemnas with both. Returning it to Riku, they use a bolt of light and dark energy to finish off Xemnas.

Afterward, Sora must help Riku walk, as he sustained a heavy injury from one of Xemnas's Ethereal Blades. They wander through the eternal abyss, and eventually come to an area of crossroads, with everyone, even the Nobodies there.

When Seto is forced to say goodbye, she starts to lose control of her emotions. The roads start to break apart and Seto reaches out to Sora. He promises to her that one day that they will meet again and remember all the fun times that they had.

Seto then wakes up in her office with no recollection of **Millennium Hearts 1**or **2**.

### Millennium Hearts Re: coded

King Mickey and Nafrini digitize Jiminy's Journal and create a digital copy of Sora and Seto to investigate a strange message Jiminy found within it. The digital journal is corrupted by computer bugs in the form of data blocks, and the Data-Sora and Data-Seto go through and eliminate them all, eventually discovering that it was Sora's own Heartless that had been corrupting the journal.

After defeating the Heartless, the Data-Seto goes even deeper and discovers that Joxy had hidden data about those who were in suffering (Roxas, Xaibak, Naminé, Joxy, Oni, Adena, Axel, Terra, Aqua, Ventus, Melody, Materia, Vanitas, Ansem, Xemnas, Xigbar, Vexen, Saix, Demyx, Luxord, Marluxia, Larxene) within the real Seto's "missing" memories. With this knowledge, Nafrini writes a letter to Seto asking for her to go to Angel Rose Pavillion for "special training". Later, Mickey and Nafrini meet with their old Master, Yen Sid, who reveals that with Ansem and Xemnas's Dark Silhouettes' defeat, Xehanort has returned and that Sora, Luka, and Riku must undergo the Mark of Mastery exam to properly combat him.
