When Fuyumi was very little, her mother met her doppelganger from the Demon World. Therefor, the two women was combined into one woman due to magic, and became the woman known as Neyn. After a long debate between the two husbands, who now shared one wife, Fuyumi's father decided that i would be best if Fuyumi was raised in the Human World, and the woman now known as Nyen, who was partly his wife, traveled to the Demon World to live with her other husband; Heads Hydra, and their daughter Bell. Fuyumi doesn't remember any of this since she was too young to understand what was going on at the moment, and her father decided that it was best not to tell her.
Fuyumi grew up to be a very kind, but also pretty shy and sometimes even naive young woman. She had a pretty normal upbringing, living with her father, and attending school. But all this changed when she walk through the magical portal known as "The Black Curtain" witch happened to be in her room, and she found herself in the Demon World. She would have been killed, if not for Staz, who had a huge interest in her, since she was from the Human World, witch he adored. The fact that she was Japanese only made her even more interesting(and attractive) for the nerdy vampire.
But she was soon eaten by a huge carnivorous plant, when Staz left her for taking care of someone who wanted to take over his territory. And since Fuyumi was in the Demon World when she died, she became a demon herself, a ghost to be specific. Staz behavior toward Fuyumi changed drastically, now that she is no longer a creature of flesh and blood, and the physical attraction toward her was gone. But he made a vow to her; to find a way to get her back to life(in order to suck her blood, but he doesn't say that).
After a quick visit to the Human World with Staz, Fuyumi learns that she cant stay too long, since she has a low amount of magic, so she will start to disappear when she runs low. To make sure she wont, Staz feed her some of her magic by letting her drink some of his blood. This would later show to be a mistake.
Before leaving the Human World, Staz makes sure to use his demonic powers to make everyone believe that Fuyumi is still in the Human World, so that no one will notice that she was dead, once she returns home as human.
Coming home, the are met by the witch Bell Hydra who accuse them for stealing her "Black Curtain." Bell kidnaps Fuyumi, an order Staz to get her a certain pair of demon underpants from a demon shop. As Staz gets the underwear, Bell explains Fuyumi that she is looking for the thief who stole her "curtain," so that she can marry him.
After getting the underpants, Bell tells them that the only way to resurrect Fuyumi is by the use of "The Book of Human Resurrection" that is in the possession of Wolf, Staz old friend.
Staz ask Wolf for the book, but even though Wolf is Staz friend, just giving the book away is not a option for a territory boss, so he challenge Staz to a boxing match, with the book as the prize. But if Wolf win, he gets Fuyumi. At the fight, Fuyumi has the function as the ring girl, much to her dismay.
Wolf has the obvious advantage with his werewolf strength, but Staz succeed getting the upper hand by draining Wolf for magic. But the fight almost ends badly, when Wolf starts insulting Staz, witch enrage Staz to the point that he attempts to use his magic to crush Wolf's heart. Staz is luckily stopped by Fuyumi, and the match ends without a winner. But Staz gets the book anyway, since Wolf never had it. Bell just wanted to test Staz, and gives it to him.
Staz travels to Acropolis to find the author to the book, and leaves Fuyumi under Wolf's protection. But it is soon shown that Fuyumi is slowly starting to fade. After Wolf takes her to Franken Stein, a demon doctor, it is revealed that she is no longer capable of absorbing magic from the Demon World's atmosphere now that she has fed on Staz's blood, and without magic, she will seize to exist. The only way to keep her from fading away is by feeding her vampire magic. Franken has some on store, until Staz returns and can feed her himself.
Staz eventually comes home, and can now feed Fuyumi with the kind of blood she needs. She is also introduced to Staz's brother Braz, who takes a sample of her, and promise to start working on resurrecting her. He plans on doing so by making a replica of her body, and attach her soul to it. When Braz leaves, the youngest Blood sibling named Liz is left behind. Fuyumi shows much kindness toward the little girl, and they start bonding, almost like sisters. Liz is the first to notice that Fuyumi has been abducted, since they slept in the same bed.
At the middle of the night, a blond boy named Knell abducts Fuyumi by the use of spatial magic, and brings her to the Hydra family's palace.
at the palace, she is greeted by Lady Nyen, who are very happy to she her daughter after so many years. She is finally told why her mother left her and her father.
While changing clothes, Bell ask Fuyumi how she fells for Staz, and if she is in love with him. She says that she appreciate that he try so hard to resurrect her, and that she cares for him, but If it' love, she do not know, and will probably only find out, once she is back to life.
Then, out of nowhere, Fuyumi is teleported outside the palace. The very confuse(and half-naked) Fuyumi find Staz lying on the grass sleeping. When he wakes up, he starts to act all of a curtain very nice toward her, and even trys to smile, witch just looks creepy. Staz tells Fuyumi that he has done her a great deal more harm than good, and promise her that he will never leave her side, and that she is now in charge. They leave the palace together on their quest for Fuyumi's revival. Their next destination is Braz palace.
Powers & Abilities
Fuyumi died in the Demon World, and sine she was human and not demon, she became a ghost. She has no magical powers besides being a demon, witch makes her immune to certain kinds of magic that only works on humans. But as any other ghost, she can consume magic from other demons, and has the potential to become a very powerful hybrid. And since she has fed on Staz's magic, she is now a hybrid-vampire. Franken believes that Fuyumi will eventually become even more powerful than Staz.
But unlike other demons, she cant bread the atmosphere in the Demon World to consume magic, and therefor MUST feed on other demons.
Fuyumi is also a very good cook.
