History
When Hakuei was young, her father Hakutoku Ren, the First Emperor of the Kou Empire, and two of the princes, her brothers Hakuyuu and Hakuren, were killed in a fire during a revolt set up by her mother, Gyokuen Ren (though she has only recently learned of this fact). After the revolt, Gyokuen told Hakuei and her younger brother, Hakuryuu Ren, that the current Emperor, her uncle Koutoku Ren, will adopt them and they will still have the title of princess and prince. After that, Hakuei thanked and began to console her mother.

Sometime after this, Hakuei and her assistant Seisyun Ri, conquered the Dungeon of Paimon, with her obtaining the Djinn. Also, Hakuei became a General of the Western Subjugation Army of the Kou Empire, which was situated near the residents of the Kouga Clan in Tenzan Plateau.

Kouga Arc
Hakuei Ren first appears when saving Aladdin off an out of control horse. She is with her assistant, Seisyun Ri, and Ryosai. She introduces herself and formally asks the Kouga Clan to become apart of the Kou Empire, but they refuse when Ryosai hits Toya, since she offered horse milk to the Princess. Then, they go away back to Kou Empire's army base. That night, Aladdin goes to visit Hakuei to have a talk with her. She tells him how she doesn't want war and Aladdin becomes able to trust her.

Another day, some of the soldiers appear hited by arrows. Ryosai tells Hakuei they were attacked by Kouga Clan's members. Suspicious of what he said, Hakuei and Seisyun Ri go to the Kouga Clan to talk to them, only to be ambushed by an angry Kouga Clan. They accuse Hakuei's soldiers of attacking Baba, the Kouga Clan leader. As she came to understand the situation, she became very angry with her own men. Baba suddenly appears and, even wounded by an arrow of Kou Empire's army, tells Hakuei that they would join the Empire, much to the dismay of everyone else.

Back at the army base, Hakuei is betrayed by Ryosai, who is revealed to be the cause of the misunderstanding. She is attacked by arrows, but uses the powers of her Djinn, Paimon, to defend it. She starts fighting with Seisyun against the army, but despite her efforts, she is captured since the soldiers were in great numbers. When she is about to be killed by Ryosai, Aladdin appears and uses Ugo to defeat him. As Seisyun wakes up, Hakuei explains how they both captured a Dungeon. Hakuei's Metal Vessel lights up and when Aladdin touches it, it summons a materialized Paimon. Ugo is summoned and they have an unheard conversation, but Paimon explains how she can't help them. Paimon says she only wants to see Hakuei as King. After talking to Paimon they separate with Hakuei offering to introduce Judar to Aladdin.

Pirates Arc
She is seen in Hakuryuu's memories of when half of their family were killed.

World Exploration Arc
She is rushing to the Kou Empire on horses with her Household, Seisyun and over 100 members of the Kouga Clan, behind. In the Imperial City, Koumei is amazed at how quickly she arrived and asks Hakuei who are these people. She explains that as her Djinn, Paimon, seems to be a fertile Djinn, she has so many Household members and thanks to their strength, she was able to fight until now. Koumei states that when it comes to number and the battle power of Household, Hakuei is second to none. Then, Hakuryuu also appears with his Household, creatures created with life magic, Hakuei tells Koumei that they arrived quickly thanks to his help. She seems quite worried about the change in her brother's personality. Then, they enter to the imperial palace and when Kouen arrives shortly after that, Hakuei bows to him.

At night, Hakuei goes with Hakuryuu to the library where Kouen is. She smiles and says that Kouen's appearance doesn't quite suit him, calling him "Lord Kouen". He agrees with her and says to Hakuryuu that he wanted to have a talk with him. Kouen then starts talking about King Solomon, who created the Metal Vessels, and the Toran Language. Kouen says that our world will become one, for that reason, a single King must control de world. Then, he asks Hakuryuu and Hakuei to lend their strength to him.

The next morning, Hakuei and her siblings head to the funeral of their uncle and former emperor, Koutoku Ren. She walks into the room and her mother, Gyokuen Ren, greets her children. She is worried when her mother said that the now deceased emperor was sick for quite along time and it suddenly became worse. She is shocked as everyone when Gyokuen, instead of Kouen, became the new Emperor for the Kou Empire; and for the state of affairs if the Imperial Court split into two: one siding with Kouen and the other with her mother. She asks her mother to reconsider taking the throne, but was cut off by Hakuryuu saying that their mother should take it. She and her cousin, Kouha, are shocked at this statement by Hakuryuu and the repeated agreement of the persons echoing around the room.

After the funeral, Hakuei goes after Hakuryuu and asks why he did such a thing. He says he obtained the power and now he will protect her. He finally tells her the truth about the death of their father and brothers: was Gyokuen who assassinated them. Hakuei is surprised, but Hakuryuu supposes she already noticed that their mother changed and the group of priests behind her are the Al-Thamen, who are manipulating the Kou Empire. Hakuryuu grabs her hand, saying they will destroy them together and take back their old nation. With a dark expression, he tells her that he lived until today just do realize that. Hakuei is horrified and reminds him what Kouen said one day before: "Division invites destruction.", that is why Kouen will not allow an absurd thing such as a civil war; she says the world is one. After the talk, Hakuei asks Hakuryuu if something happened to him and it's not like she doesn't believe him, but now she needs a little time. Then, she apologizes to him.

Magnostadt Arc
Hakuei is somewhere with her army, when her cousin, Kouen, calls her and the other Kou Metal Vessel users through long-range Clairvoyance Magic to go to Magnostadt. She answers "Acknowledged" and enters in her Paimon Djinn Equip form.

Aladdin is in trouble because he doesn't have any staff and cannot use his Magic decently when Hakuei uses Paimon's power to catch the Black Djinn and throws them to where the Kou warriors are. Her family destroy the Black Djinn and Hakuei, Kougyoku, Koumei and Kouha appear with Kouen in the centre. Aladdin sees Hakuei and calls to her, who is surprised to see him. Hakuei asks Aladdin why is he here. Koumei asks her if Aladdin is someone she knows, and that how are they related. Hakuei recalls what happened with the Kouga Clan and Ryosai and, with a smile, answers that Aladdin saved her life.

Hakuei is fighting against the Black Djinn and says that there's no end to this, and that they have to sever them from the source, that black sphere, the "medium". Alibaba agrees with her, and says to let's do it. Hakuei uses her power to create a path with wind and wrench the Black Djinn open, so Alibaba can pass through them and attacks the "medium" directly, but fails. A bit after, she and the majority of the Dungeon Capturers are tired. Kouen keeps attacking the Black Djinn alone, and she screams his name when six Black Djinn fusioned attack him. When Kouen digs a hole in the earth with his Agares Djinn Equip, she, astonished, says that he has stimulated the veins of the earth and pulled out a lava flow.

After Kouen has grabbed Alibaba and forced him to get into the lava flow, Hakuei makes a detailed explanation of what Kouen truly said: that if things continues like this against such a great number of opponents, things will get out of control, so Kouen wants the support of Alibaba after he replenishes his Magoi in the volcano because he controls a flame Djinn just like him. After her more polite and reasonable explanation, Aladdin has doubts about if Kouen really said it. She agrees when Koumei says that they have to protect them so no Black Djinn gets close to them.
