Fai D. Fluorite (ファイ・D・フローライト, Fai D Furōraito ) , his first name being pronounced like the word "eye". It is stated in the manga that he is named after the gemstone Fluorite. It was later revealed that his real name in Greek language is Yuui ( ユウイ, Yuui ) .

Fai is first shown sealing away King Ashura of Celes Country at the bottom of a pool. He transforms his creation Chii (originally from Chobits) into a net-like shield, instructing her to alert him if King Ashura should awake. He then uses his magic to transport himself through dimensions, to the shop of the Dimension Witch, Yuuko. Out of his traveling companions, Fai's motives for joining the group are the least clear. He is the only one to arrive at Yuuko's Shop purposefully, by use of his own means. His wish is to never return to Celes country, but as the price for this would have been too great, so he travels worlds with the group instead. He fears King Ashura’s awakening, believing King Ashura would chase him through different worlds.


From Syaoran's group of allies, Fai is the most energetic, while being enigmatic at the same time. He appears to be happy-go-lucky and good-natured, and acts very carefree. He often teases Kurogane, calling him ridiculous nicknames such as "Kuro-rin" and "Kuro-tan". However, Fai has been shown to be as perceptive and a skilled fighter as Kurogane. He also appears to carry a deep emotional burden, and values his own life very little. In battle, Fai doesn't bother to fight very hard for his life, and will only do so if someone he cares for is in danger. Though he hides his unhappiness well, Kurogane is able to sense the disguise. When he confronts him about it, Fai usually gives very dark and enigmatic answers. His past is a profound motivating factor for his actions and is something Fai cannot seem to overcome; instead he masks it all with a smile.

Fai is emotionally distant, refusing to allow anyone to become too close to him. Despite this, Kurogane has noted that the mage has become attached to Syaoran and Sakura. Fai's behavior changes significantly after he becomes a vampire and is forced to regularly drink Kurogane's blood to survive. Fai becomes much colder and very solemn around everyone, and begins addressing Kurogane by his real name in order to try to kill the bond between them, confessing to Yuko that he had 'crossed the line' that he had drawn for himself and become too close to Kurogane. However, after the events in Celes, Fai seems to have gone back to the way he was at the beginning of the series, as he once again addresses Kurogane with strange nicknames, and he seems to give a real smile now.

Fai worries about his companions and would go as far as breaking his own personal vows to ensure their safety. Kurogane confronts Fai about this, and states that Fai should figure out what he's doing with his present and future, because his past has nothing to do with either Kurogane or their younger companions. Fai tells Kurogane that he should not worry or care about him, which Kurogane responds with "I don't care about your past. So prepare your current self." After Kurogane leaves, Fai collapses, emotionally exhausted, and states that this is too hard for him.

Twins Fay and Yuui

When Fai's past is finally revealed, it's known that his real name is Yuui. It is shown that "Yuui" was born in Valeria Country, with a twin named Fai. Though the birth of the second prince's son was highly anticipated, the birth of twins was considered to be a bad omen. Shortly after their birth, the second prince died, and their mother committed suicide out of guilt for giving birth to them. In addition, the country suffered many misfortunes, and the twins, when combined, bore powerful magic that rivaled that of the current king.

The king decided that making them unhappy was the only way to break the "curse", and since each refused to kill the other, they were locked up separately in a place where magic is ineffective and time does not flow: a tower residing in a deep valley. Fai was imprisoned atop the tower, and Yuui was confined at the base of the tower. Both were condemned to stay there "until the world's destruction."

Despite their unhappiness, the number of bodies dumped into the base of the tower began to grow. Yuui tried endlessly to climb up towards Fai, so they could escape, but he did not succeed. Eventually, the king became insane, and he executed everyone in the country, except for Yuui and Fai. He then jumped into the valley himself and committed suicide in front of a horrified Yuui, reminding him that their birth was the reason for the country's misfortune, and that they would now "pay for that sin" by being the only people alive in Valeria.

Eventually, Fei Wong Reed appeared from another world, and offered to free one of them. Fai chose to save Yuui, resulting in Fai being thrown from the tower to his death. Fei Wong then tampered with Yuui's memory to make him think that Yuui had chosen to save himself at the cost of his brother's life, allowing Fei Wong to use his guilt in order to turn him into his servant. In order to bring his twin back to life, Yuui allowed Fei Wong to bestow two curses upon him, one of which was removed from Yuui's memory. Fei Wong then told Yuui that someone would free him from the valley, and that he would have to go on a journey, protecting "a princess" (Sakura), and killing any obstacles along the way. Fei Wong then tells Yuui that when he finds a magical feather, he should put it into Fai's body to prevent it from rotting, and that he should begin his journey when he finds a second feather, which he should give to Sakura.

Later, King Ashura came to Valeria from another world in order to retrieve Yuui and took him to Celes. When Ashura asked what Yuui's name was, Yuui said "Fai". Ashura later gave Fai the last name "Fluorite", the name of a precious mineral, and he eventually earned the title 'D', given to the highest magician in Celes. And thus, Yuui became the protagonist "Fai D. Fluorite". He found his two feathers while helping villagers during an avalanche, and decided to use one to create a person in his mother's image; Chi.

Ashura eventually tutored Fai in magic and comforted him whenever he felt unable to overcome his dark past. When Fai discovered that he could only learn "magic that kills people", Ashura told him that his smile held the ability to heal others. In exchange for everything that he had done for him, Ashura asked Fai to promise that he would eliminate anyone who threatened Celes.

Due to Fai's first curse, Ashura traced a magical seal on Fai's body in the form of a Phoenix tattoo, which suppressed his powers from growing any further, and though Fai protested, Ashura told him that Fai's first curse would break after it was fulfilled once, and he wanted to be the one that Fai would kill. Ashura then erased what he had told him from Fai's memory.

Several years later, a mysterious and deadly monster began to kill Celes's innocent civilians. Fai swore to defeat the beast, but found out that Ashura was the monster. Fai, at first, blamed himself for what happened to Ashura, thinking that "the curse of the twins" was what had caused Ashura to kill, but Ashura told him that his magic grows when he kills, and that he always knew that he would become a murderer, even though he was not sure why. Fai realized that Ashura had brought him under his care for the sole purpose of killing him when he reached this state. Unable to bring himself to kill Ashura, Fai cast a spell on him, putting him into a deep sleep. However, no magic spell was permanent, so the king would eventually awaken. In order to avoid having to face Ashura when he woke, Fai used his magic to teleport himself to the Dimensional Witch, where he began his journey.

Syaoran reveals that Fai's past may have been changed after Syaoran created the distortion due to his turning back time, and that Fai might have been born originally without a twin.

Events before the Tokyo Arc

At the beginning of the series, Fai vows that he would not use his magic again without the tattoo on his back, but breaks the vow when he creates a shield in Lecourt Country around the group in order to save them. In the Tokyo arc, he again uses his magic to try and reseal, the living heart of Clone Syaoran. The clone then proceeds to eat Fai's left eye, which contained half of Fai's magic, saying he needed Fai's powers in order to get Sakura's feathers for himself. Brought to the brink of death from the shock of losing one eye, Fai resists attempts to save himself, reasoning that the clone would be unstoppable with his powers, but that the magic would perish if Fai dies.

Fai's request to die is ignored by Kurogane, who saves him by following Yūko's advice. Fai is then fed Kamui's blood and turns into a vampire, one with accelerated healing abilities but who needs to consume blood to survive. Because it is Kurogane's wish and not Fai's that he should live, Kurogane from then on has to take responsibility for Fai's life: the blood Fai received was mixed with Kurogane's blood, so that Fai can only feed from him. Fai now has to drink Kurogane's blood on a regular basis in order to survive; he literally needs to depend on the ninja to live. After these events, Fai stops addressing Kurogane by silly nicknames and begins to use his full name in order to distance himself. Fai confesses to Yūko that he had not realized how close the two of them have become, and that, if he forgives him for saving his life, they would be even closer.

Fai's outward behavior becomes much colder in the following volumes. He drops his joking and happy-go-lucky demeanor, and smiles less. His interactions with the rest of the group becomes very distant and formal. The exception to this is Sakura, whose behavior (at the time) is as dark as his. Fai grows close to her in their mutual suffering and pledges loyalty to the princess. When Sakura informs him of her wish, he promises to help her without informing the others and without asking for more details.

At the end of the tournament in the Infinity arc, it is revealed that Fai had a curse placed on him: he would kill anyone with magical abilities that surpassed his own. Seemingly possessed, Fai stabs Sakura after she receives two additional feathers; one from Chi, and another from a robot resembling Freya from Chobits. Yūko states that the additional feathers increased Sakura's magic, thereby surpassing Fai's halved magic. Sakura foresaw this in a vision, however, and made a wish to Yūko to prevent herself from dying: her body is taken to Celes and her soul to a dream world.

It is later revealed that Fai has lied to the group on several occasions. He lied about the whereabouts of two of the feathers; the first one, which he seemingly removed from Syaoran's clothing in Volume 1, was actually with him from Celes. The other one was the one he had used to make Chi, which he pretended to know nothing about. After this revelation, he resolves to return to Celes in order to save Sakura's body, but a price had to be paid for the four of them to go to a specific country. Fai offers up everything that could be seen with his right eye in order to return to Celes, meaning that he would go blind. To prevent this, everyone agrees to offer up a fourth of the price by handing over their tournament money. Fei Wong Reed, who is secretly watching the group, then states that Fai was supposed to have stabbed Syaoran after the latter regains his original powers, but Sakura foresaw this and created a situation to activate Fai's curse before that happened. He also reveals that, even though Fai's first curse is now broken, he has yet another curse which only works in Celes.

Events after the Tokyo Arc

Later, after entering Celes country, Ashura uses his magic to show Syaoran, Kurogane, and Mokona visions of Fai's tragic past. This causes Kurogane to unsheathe his sword and attack Ashura and Fai. Though Fai is horrified that his comrades now know the extent of his secrets and betrayal, he decides to fight back with magic to protect Ashura, and also due to his vow not to die before he saves his brother. The two engage in a fierce battle, and in the mayhem, Kurogane damages the body of Fai's twin, and in that moment of weakness, manages to overpower Fai. Kurogane then demands Ashura to tell him why he showed them Fai's memories, and he responds by saying that he only wanted Fai to "grant his wish" and kill him. Ashura launches vicious spells against Fai's comrades in order to force his hand, which causes one of the massive ice stalagmites that he conjured to pierce Kurogane in his right side. Angry, Fai attacks Ashura, retrieves Sakura's body, and places her with Syaoran for protection. Fai then decides to kill Ashura for the sake of both their wishes, but Fai's lack of a will to live and the loss of his eye prevents him from fighting at full strength. Ashura overpowers him, and tries to kill Syaoran and Sakura in order to draw out his true power. However, Kurogane intercepts the attack and stabs Ashura with his sword, killing the king. The feather in Fai's brother's body then shows Fai the true reason for his death. It returns to Sakura's body and the corpse disintegrates, finally at rest.

Just when Mokona begins to transport the group to the next world, Fai's second curse activates, which causes Fai's magic to create a form of cage, trapping the group in Celes. Fai then declares that his magic does not get stronger the more he uses it -- in fact, the more he uses magic, the closer he is to death. With everyone unable to transport to another world, Fai attempts to use the last of his magic to transport his comrades, intending to sacrifice himself in order to save them. However, due to his halved magic, Fai is only able to transport Sakura, Syaoran, and Mokona. Using a magic earring Mokona wears, Syaoran creates a hole in the sphere where Fai and Kurogane are trapped, but Fai's curse uses him as the spell's anchor, meaning Fai cannot leave. Since Fai had used up all his magic in evacuating the others, Kurogane cuts off his own left arm, which Fai casted magic on earlier, and leaves it behind in the sphere in exchange for Fai.

In Nihon country, the next world, Fai is shown to be weeping and emotionally distraught over Kurogane, who is bleeding and unconcious due to the loss of his arm. Tomoyo pets him and calms him by saying that Kurogane will not die. When Kurogane awakens, Fai enters the room wearing a furisode. He punches Kurogane, smiles, and playfully tells him that it was for revenge. He does this while addressing him as "Kuro-sama," which shows that Fai is willing to call Kurogane nicknames again, reinvigorating their relationship. Fai then trades his remaining magic to Yūko in exchange for a false arm for Kurogane, and because he lives off of Kurogane's blood, Fai does not lose sight or die from offering up the last of his magic.

It is revealed in chapter 175 that the magic in Fai's right eye reduces his life and power the more it is used while other (the left eye that the Clone Syaoran ate) gets stronger.

Later, when Sakura is killed during the two Syaoran's battle, he reveals that he knew Sakura was a clone all along. He then offers to go with Syaoran and Kurogane to save both Sakuras.

That night, Fai goes to meet Syaoran, who was sitting on the roof, and tells him that he should rest. There, Syaoran thanks Fai for taking care of and supporting Sakura. When leaving the Nihon country, Fai is seen in the clothes he wore at the beginning of the series.

Clow's Future Arc

In chapter 184, the group finally enters Clow Country, where they end up repeating the same day over and over again due to a spell. During one of the days, Fai finds out that Kurogane's new arm is causing him pain, leading Fai to punch and scold Kurogane for not informing him. Their relationship returns to normal after this, even though Fai promised he wouldn't get close to him again.

When Syaoran informes Fai that, if not for Syaoran's wish, his twin brother may never have been born (and thus, never would have died) Fai's expression is that of shock and pain. Still, he wholeheartedly agrees to continue with Syaoran on his quest. He and Kurogane deal with Fei Wong's minions while Syaoran battles the Clone, but the Clone blasts both of them after seemingly stabbing Syaoran. Fei Wong also detects that Fai no longer possesses magic.

As the Clone dies, he ejects the magic he stole from Fai and gives it back, restoring Fai's magic and his left eye which the clone Syaoran originally gouged. The magic attempts to draw out Fei Wong's hiding place, and Syaoran, Fai and Kurogane strike, before "Fei Wong" shatters, revealing Kyle beneath a mirror of Fei Wong. Fei Wong himself then appears holding Clone Sakura's body.

The time-space continues to collapse. It's then revealed that Tokyo is actually Clow's past, and the "power of the ruins" is actually the feather that Clone Sakura left in Tokyo.

As Fei Wong takes her feather, he is attacked by Kurogane and Fai. Meanwhile Syaoran finally grabs real Sakura's hand but Syaoran's choice to take Sakura's hand also causes someone else with her same fate to be called back to death. The person who had suffered the same fate as Sakura was in fact Yuko.

Before her death, Yuko releases Syaoran's parents whom use their magic to "cleanse" the memories in the feathers, thus restoring the world and everything Fei Wong destroyed.

After this, the clones and their original selves get sucked into the tube and later break out. Kurogane takes advantage of Fei Wong's confusion and strikes him, delivering the final blow.

At last, after escaping from the void, "Syaoran" returns to Clow, where he meets "Sakura", Kurogane, Fai and Mokona. Both Syaoran and Sakura absorb a feather that their clones left behind.


"Sakura", "Syaoran", Kurogane, Fai and Mokona are back at Clow Country.

Kurogane and Fai hold a conversation, in the which they argue about the previous events, how "Syaoran" is now left alone in the world, left behind, without his parents and wants to change that reality (which is why he chose the price he did). Additionally, they explain that the feathers that the originals absorbed are actually the clones' memories- or souls.

Later on, Syaoran and Sakura meet at the clones' favorite place. Kurogane and Fai argue what their next move is, and find Mokona in the way. At this point, Kurogane, Fai and Mokona arrive at the scene, the three of them planning to join "Syaoran" in his new journey. Fai tells them that he has no home to return to, and since he's got his magic back and he's a good cook he'd be useful in the journey.

Mokona shows them Black Mokona's ring, which had stored Watanuki's and Clone Sakura's memories inside. This way, they'll be able to return to Clow and visit Yuko's old shop more often.

Afterwards, Sakura stays in Clow, wishing and knowing that they'll meet once more.

The extent of Fai's magic

Fai is an extremely powerful magician.

Fai's curse

Until the curse is broken, since the removal of his sealing tattoo, Fai never directly encounters any beings with magic greater than his. Among others, that would include

  • Masayoshi's feather-empowered Kudan
  • The feather-empowered Ryanban and Kishimu
  • Dr. Kyle
  • Seishirou
  • Ashura-ou
  • Anyone in the country of Lecourt

These people have less magical power than Fai even after he loses half his magic

  • Kamui, Subaru, and Fuma
  • "Clone" Syaoran with half of Fai's magic
  • "Original" Syaoran

Finally, Sakura empowered by two feathers possesses more magic than Fai, and the curse is activated.


When Fai entered the Dimensional Shop, Yuuko had placed herself in another dimension to avoid the curse's activation.

Powerful, but non-magical people can't activate the curse.

Likewise, powerful and magical non-people can't activate the curse.

Though individual feathers possess great magical power, this power vanishes when the feather is absorbed by Sakura.

A person can be magical even without being able to use their magic power.

Fai's raw power

Even without explicitly using magic, Fai can detect and assess various types of magic with no effort.

In the world of Lecourt, Fai was able to create a barrier that was not only able to isolate them from the world, but also from the transportation restricting magic that was in place, making him more powerful than any of the magicians there.

Though Fai agrees at the very beginning of the journey that it would take all he had just to travel through dimensions once, it turns out that this is not the case, making him an incredible exception among magicians (as even Yukito and Tomoyo-hime, both extremely powerful magicians in their own rights, were only able to do so once).
