Hilda

, full name, is a Demon that serves as Beelzebub IV as a wet nurse. She is also one of the main female protagonists of the series.

Appearance
Hilda is an attractive young woman with blonde hair that covers one side of her face and is tied in a bun, green eyes and a well endowed chest. Her clothes are mostly elegant and black with frills and white quillings, thus resembling elegant gothic lolita fashion.

She is seen wearing other outfits on a few occasions. One occasion being right after she wakes up, where she was wearing a modest pink night gown with her hair down. In one chapter, she was shown wearing a yukata while playing with fireworks along with Lamia.

When she infiltrates Oga's current school she dresses in the Saint Ishiyama High uniform, though she complains that the shirt is "a little tight."

Personality
Hilda commonly displays a cold and impassive demeanor, a character trait that she breaks only on rare occasions. (excluding her interactions with Be'el). Toward Be'el she is very affectionate and protective, acting as the role of the mother and preforming the task a mother would such as cooking for and washing Be'el. She often knows more about the current situation than any of the other protagonists and is easily able to manipulate others into doing what she sees best. Hilda also has a fondness for extremely spicy foods, such as super spicy habenero buns.

She is shown to be just as bloodthirsty and violent as Oga, a trait that earned her the nickname "Oga's Bride" at Ishiyama. In a fight she displays a complete confidence in her own skill and power, regarding her opponents calmly and often taunting them in mid battle.



She enjoys teasing and tormenting Oga, frequently making marks about his intelligence and (in her own mind) poor parenting skills. In the beginning of the series she is openly disapproving of Oga as Be'el's parent but after the delinquent defeats Toujou she becomes much more accepting and warmer towards him, even thanking him afterwards. But she still bickers with him. After spending some time with Oga and Baby Beel, it seems that she changed in her behaviour, as Izabella noted that her personality has changed since coming to human world and wonders what kind of human is responsible for this change.

During her memory loss, her personality became significantly more innocent. She no longer showed Oga any animosity, and it's even hinted that she has started to develop romantic feelings towards Oga (she blushes whenever she is near him), though it did not last after her memories returned. It is hinted that the personality of Hilda after her memory loss is her original character. The cold and impassive Hilda before was just a mask that Hilda put on herself by killing her own emotions. She also became noticeably kinder, becoming a great deal more affectionate towards Be'el, whom she called 'Beelze', instead of 'Young Master', and Oga, whom she referred to by his first name, something only his family has done. This, however, did not completely extend to Furuichi, whom Hilda almost instictively feels to be nothing more than "a creepy douche".

After her memories returned, her behaviour returned to normal, having threathened to murder Oga when he insulted her cooking.

Plot
Hilda originally came to the human world on the Demon Lord's command to raise his son, Kaiser de Emperana Beelzebub IV, to be a 'good' human destroyer. Beelzebub however, got so attached to Oga Tatsumi that she now observes him and his progress in being the future demon lord's parent.

At first, she was completely against Oga to be her master's human parent. But since she was loyal to Beel, she followed what her master wanted and gave Oga a chance. She looks over both of them and their developments, not only in strength, but bond as well.

Touhoushinki Arc


Himekawa, the second member of Touhoushinki, planned to kidnap Hilda, who he and the rest of the delinquents believe is Oga's wife, to attract and take him out. He orders the Team Caras to bring her to him, and they bring her along with Furuichi. The change of plans makes Himekawa angry and decides to lure Oga out. When he asks for Hilda's phone and she said she didn't have one he shoots her with Suzuki's acid gun to erode her dress and finds out that she really didn't have one. So, Furuichi gives him his own phone to call Oga. When Oga gets there through Alaindelon and refuses to work for Himekawa they fight and Himekawa is overpowered. He tries to make use of the hostages, but Hilda defeats his subordinates and Oga knocks him out. Then Hilda takes Oga's wrist to check the Zebul Spell, and Oga finds out that she got caught on purpose to measure Himekawa's strength. When Oga tells her that it wasn't only him but Baby Beel was also worried about her, she replies that her master doesn't care for her, rather he is only affected by Oga's anger. When Oga wants to give Beel to Aoi Kunieda, she meets her and tries to pick a fight with the Queen. Aoi is first outraged of fighting Oga's bride, misunderstanding Hilda's role in Oga's life. Thinking that Beel was Hilda's son that she abandoned to Oga, Aoi violently rushed against the maidservant, but she was easily outmatched by the powerful woman. Lately, when Baby Beel caught a fever, she was so worried about the child's health and seeing Oga was showing no interest in Beel's situation, and wondering if he could go more than 15 meters from him, she kicked him out of the house and disappeared. She came back when Oga also came back from his first fight, and lost, against Tojou; she went to the demon world to bring a doctor, Furcas Rachmaninoff and his assistant Lamia, to find out Beel's problem, but he was gone. So she stayed with the two of them when thay tried to recreate the tie between Oga and the Demon Lord. She reappeared during Oga's fight with Tojou, to assist at her Master newly found healthy condition.

Saint Ishiyama Arc
Hilda transfers to Saint Ishiyama and shocked everyone with her sudden arrival. Upon arguing with Kunieda with the seating arrangement, she already gained the fame of being the wife and Kunieda being the mistress. Hilda successfully got the chair next to Oga, though. When the class that the match between the Rokkisei and Ishiyama was volleyball, the whole class froze. Kunieda first tried to get everyone to practice but miserably fails because Furuichi was the only one there and that was just because of his perverted goals. Hilda, saying that her master really wanted to defeat the guy called Miki, agreed to be the one to make the other guys want to practice. The red tails were pretty shocked and thought that Hilda will use the normal way of seducing the men and were pretty unsure of her big declaration and commented on how she will be a laughing stock if she wasn't triamphunt over her words. Successfully leading the men into practicing through a sick and stupid joke of kidnapping them, she manipulated the whole situation, like a good wife should do and made the girls' eyes widen in disbelief.

Hilda makes a proposition that anyone who can return her serves will be the captain. Because of the sheer strength and speed of the ball, everyone became intimidated until Kunieda Aoi volunteers to do it. At first, Kunieda was astounded because of the speed, saying that she did not even see a ball pass by. By the second serve, Hilda made a jump serve and made sure it was tougher than the last one. Kunieda returned the serve. Hilda smiles her usual cool grin and decides that Kunieda Aoi will be the captain of the team. Kunieda commented on how it seems that that was Hilda's original intention from the very beginning.

Prince En Arc
When the battle between Oga and Karyia ends a hole between the human world and the demon world is opened in the roof of the gymnasium which Saotome Zenjuuruo had to fix. When he ends fixing it Hilda show's up asking him if he was one of behemoth's men. When they start fighting he makes pervy comments about her underwear and harasses her by grabbing her breasts, making her very nervous, pushed by her anger she releases her power that's when Zenjuuruo takes her seriously and immobilizes her. She then notices that he is a spell master.

Kunieda pulls Oga aside to ask him about what Beel and Hilda ' actually ' were, already suspicious about their true demon identity. Oga tries to explain but he can't remember Baby Beel's real name, getting him upset making him crawl away crying, he bumps into a woman that looks like Hilda, Yolda (Hilda's sister). This helps him to recollect Be'el's complete name, Kaiser Emperana Beelzebub IV, and tells them that they shouldn't make the demon lord's child cry like that. Furuichi calls her Hilda, she approaches him and tells him not to put her together with that 'whore' knocking him out. After that she goes to Oga and asks him if he could please die and try to kiss him, in that moment Hilda falls from the sky in a lightning bolt stopping Yolda from kissing him. Hilda tells them to go away, and that the woman was after her, suddenly two other nurses show up telling Yolda to stop that, it's revealed than the existence of Beel's brother Lord En.

They go to Furuichi's house after a while, it's explained that En was sent there to help Beelze in his task to destroy humanity. Hilda, Oga, Kunieda and Beel return together home, in the middle of the way Kunieda splits from the group because her house is in the other way, she gets captured by Hecadoth and made hostage, Hilda and Oga make a plan to rescue her,Oga distracted Hecadoth in order to make Hilda catch Kunieda. When Hilda successfully saves Kunieda and hands her to Oga, she is stabbed by Hecadoth who reveals that the his real task was to disable her. After Kunieda wakes up and sees what happened to Hilda, Oga tells her to look after Hilda for him while he fights Hecadoth, though he is, at his current state, no match for him. Then Zenjuurou shows up and defeats the pillar, who is then teleported along with the other two pillars back to the demon world. They take Hilda back to Oga's house and Alaindelon brings Dr. Furcas and Lamia to take care of Hilda and Oga's injuries.

While Oga and Kunieda were training, Hilda recovered in a week's time. Furuichi, Lamia and the gang were fighting Prince En through net gaming for three days to find out were Prince En's exact location is. When they went to buy food and drinks for the gang, Furuichi and Lamia spotted Yolda, one of Prince En's wet nurse, and tried to catch her when she suddenly ran. When they caught up to her, they soon discovered that Prince En was staying by the next room beside where they were staying at. Furuichi and Lamia were trapped by Yolda when Hilda appeared through Alandelon's power and the communicator. She defeated the three wetnurses in a blink of an eye. She also commented on how disgusted she was of the three wet nurses. Hecatos, Graphel and Naga appeared. Hecatos quickly tackled Yolda. Hilda aimed her sword at his neck and told him she was his enemy. Hecatos, insulted, shouted mockery to Hilda, whom, in return, attacked him with her demon powers, sending him up twenty floors above. She was about to fight three of them when Oga took the show and asked her with the his manly smile if she could tag out and let him fight the three of them. She agreed.

Akumano Academy Arc
Hilda has been captured by Behemoth who revealed that Hilda is to become En's new wet nurse, but Hilda refuses.

Behemoth puts Hilda in a cell next to Yolda who is being used to get the rest of the Pillars to Earth from the Demon World. Hilda learns that Yolda is helping Behemoth because he promised her that once all the members of the 34th Pillars are brought to Earth he will let her be with En. When Hilda tries to convince Yolda to stop before she dies from exhaustion, she refuses to believe her. Hilda manages to switch places with Yolda on the last day of the transfer and learns that the transfer was already over and the two guards were planning on assaulting Yolda. Once Hilda learns this, she beat the two guards unconscious to protect her sister. Hilda manages to beat five Pillars and allows her sister to escape, but Hilda is captured and hung on a cross. Pillar Head Salamander decides to use his Lost Priminece, a fire which burns all of the person's memories. Meanwhile, Oga invades Akumano Academy alone to destroy Behemoth's 34 Pillar Squad Division and save Hilda.

Upon hearing from Salamander that Oga was on his way to Behemoth, Hilda uses up a lot of her remaining energy to scold Oga from the top of the school, asking if he was stupid. She commented on how reckless it was for him to go in there alone, endangering her master again. Oga, angered, answered back that he came to save her and she should just shut her mouth and wait for him. Hilda, shocked, did not answer.

Oga defeats most of the pillars with the help of Toujo, the Red Tails, Isabella and Sachura. When Oga and Tojo get to the roof, they pretend to be under the influence of Salamander's Flash dance and quickly dispose of Salamander. When Beel starts 'dahdling' at Oga to save Hilda, Jabberwock asks Oga if she is clouding his judgment and



shoots demonic energy at her attempting to kill her. The demonic cloud destroys the cross where Hilda was, but Oga appears holding Hilda in his arms unscathed. Hilda, barely conscious, raises her hand to touch Beel's face and says she is glad that he is all right, then blacks out. Jabberwock laughs at her and calls her stupid. Immediately Oga and Tojo start fighting Jabberwock.

Memory Loss Arc
The next day, after Akumano Academy was burned to the ground, Hilda wakes up and finds she does not have a recollection of who she is. When she explains what happened to Oga's parents, they try to refresh her memory by explaining to her about who she was (the information was false). She currently believes that she is Oga Tatsumi's wife, as well as Beel's mother. She is brighter and far more kind without the heavy burden to serve and protect her master, not remembering she had spent so many years killing her emotions. After all the pandimonium, Oga, tired from all the events that have happened, falls asleeps, and wakes up to find Hilda sleeping next to him. He runs away, afraid of this new behavior, while the confused Hilda calls out to him.

Determined to find a way for Hilda to regain her memories back because of her unusual behaviour that even he can't take, they go to school. They met different people; the red tails, Himekawa, Kanzaki, the six horsemen and others. All failed to give her any recollection of her memories. At the roof, Hilda questions Oga if she really needed to get her memories back. She was scared that if she remembers her memories and will lose the feelings of happiness that moment, she'd rather not get her memories back since she thinks she's happier that way. Oga holds her shoulders and told her with a grim face that the Hilda they know was a violent and merciless woman, taking off all hope for her to regain her memories back.

They meet Kunieda soon after, and out of women intuition, Hilda introduces herself as Tatsumi's wife which shock the life out of Kunieda. A small, violent conversation turns on between the two women with amnesic Hilda thinking that Kunieda was her husband's wife. Kunieda disapproves of her conclusion and asked where did she even based that idea of hers. Hilda then asks if she doesn't harbor any feelings for Oga which Kunieda answered with a stutter then run away, red.

At lunch, they were back on the roof top. It's shown that Hilda made a cutesy lunch box for Oga. Furuichi, filled with jealousy, tried to get the lunch box. Oga, pushing him aside, told him that it was the only thing that got better when she lost her memories then gulped all the food down. Furuichi then turned to Hilda to ask for a lunch box as well, only to see her face to face with Yolda. Yolda announces with a cd on her hand that inside that cd was a way for Hilda to regain her memories back. Hilda refuses the offer of her getting her memories back. Yolda shouts that she should put her act together which Oga agreed on. Hilda's eyes teared up and asked the gang if she was really that unwanted then run away.

When Yolda, Oga and Furuichi watched the tape, they see some of the Pillars by the river trying to catch crayfish. They soon discovered that the only way for her to get her memories back, as said by Salamander, is to get a kiss from her prince charming. Oga threw the Keyboard to the screen and destroyed the computer. He asked Furuichi and Yolda, with the most evil face, if they heard something and faked ignorance. Soon, all of the students knew about the kiss that was said to happen making Oga hide for his pride. Lamia appears from nowhere then gave Oga a potion that was made by Dr. Forcas especially for Hilda to return her memories back. Oga then looks for Hilda with Beel as a tracker.

They found Hilda by the river and was bullied by the Pillar's soldiers despite them knowing that she has lost her memories. Oga then defeats them mercilessly. Hilda thanked him then grabbed his arm to look at the scars then saw the potion which he put in his pocket. Realizing that it was a cure for her to get her memories back, she promises to take it. She smiles and told him that even if the Hilda that time might disappear but the Hilda before was probably happier. Then the potion flew into the river, shocking everyone except Oga and Beel. Faking disappointment, Oga tells Beel that Hilda won't return to normal anymore. He told her that despite her personality change, she was still Beel's mother. Oga handed Beel to her and she gave him a light kiss. Oga commented that maybe it was better that way since the food she makes became better. Hilda then asks him if the food she made back then was really that bad and Oga answered honestly telling her that it was like attempted murder with a grin only to realize that Hilda regained her memories back. She answered with an evil smile that next time it won't be attempted murder and beat the shit out of Oga.

Hand-to-Hand Combat
As a fighter she is quite skilled. Her skills gained her the nickname "Oga's Bride" at Ishiyama, as she dispatches her enemies in a similar manner to Oga (shoving her opponents' heads into walls). She has both agility and speed that makes up her strength. Even without using her demonic powers, she is shown to be strong and skillful. Saotome once commented that for a non-contracted wet nurse, Hilda is quite skillful and does very well in fighting.

When fighting Isabella, Satura and Yolda in Himekawa's building, it is shown that Hilda is far stronger than what she has shown before. She took down En's three wet nurses in hand to hand combat as easily in a blink of an eye, as commented by Furuichi. She is powerful enough shove Hecatos up through multiple number of floors in Himekawa's building with ease.

Swordsmanship
Her main weapon is a thin sword she keeps in her parasol, again fitting her Victorian era theme. However she rarely draws the sword, and especially refuses to do so against weak opponenents.

She uses her swordsmanship abilities with implements other than the blade, such as fighting with the parasol/umbrella without drawing the blade, or using random sticks, or guardrail columns.

Demonic Magic
As she is still a non-contracted demon, it is conceivable that Hilda's potential full strength has still not been shown.

The aura of her demonic powers is similar to other demons', a black field made of innumerable filaments. When united together those filaments seem to have a great destructive power, but Hilda seems to be able to use small filament-made whips to grab things, like she does when she takes the guardrail staffs to fight with Kunieda or when she catches Oga while falling down from Sodom.

Conveyance
Despite the fact that she is naturally just as fast as strong she is as a demon, Hilda rides a giant bird-like being named Ak-Baba, though she has not been shown riding it lately.

Tatsumi Oga
One of the most complex relationships of the series. Hilda often looks down on him and never hesitates to mock him. In turn, he finds her cold and manipulative personality annoying. However, it is shown on rare occasions that they do care about each other, such as when Hilda thanks him for helping her get Beel back from Toujou and when Oga became enraged at Hecatos for harming her. It should be noted that the two work extremely well together in a fight. They are also known as 'The Most Evil Couple' and 'The Strongest Husband and Wife'. Hilda is already considered as Oga's apparent bride/wife by the whole Ishiyama school and his family, thus gaining her nickname, "Oga'sbride/Wife/Wifey". Both of them (Hilda and Oga) don't really bother to correct other people's opinions, considering it's a waste of effort to explain. As the chapters pass by, Hilda's and Oga's relationship has grown in leaps and bounds naturally, even Oga's family has accepted her presence as a family member, especially his sister Misaki. Although their constant bickering is still present, Hilda gained Oga's utmost respect and also vice-versa.

A pinacle point in their relationship occurs when Oga saves her from being kidnapped by Jabberwock. Realizing that Oga's tactics wouldn't stop Jabberwock, she pulls Oga close and tells him that she is leaving Beel in his care alone, giving him a rare sincere smile. She then allowes herself to be taken by Jabberwocks dragon in order to save Oga and Beel, her parting words being "You're...the only father he has in this world" implying she has finally accepted Oga as Beel's parent. Oga, on the other hand goes as far as to breaking into Demon high school alone in order to rescue Hilda.

When Oga arrived at Akumano High, he received a very loud scolding from Hilda. She said that he was endangering her master, Be'el, again and that he was being very reckless and stupid. But Oga shouted back, with the same intensity as her voice level, that he came all that way just to save her and she should shut her mouth and wait for him. Surprised, Hilda's eyes widened and she stayed silent. As the battle between Behemoth and Oga unfolds, Oga made the rescue of Hilda as his top priority. Being impatient, Behemoth surprises them with a beam of demon power aiming towards the crucified and almost unconscious Hilda. Oga moves quickly to get Hilda before getting hit by the blast. The barely awake Hilda caressed Be'el's cheeks and told him how glad she was that Beel was safe before completely falling out of consciousness. Behemoth laughed and commented on how stupid she was. Oga became filled with anger and told him to NOT laugh at her. He attacked him due to him mocking her loyalty.

By the time the Akumano High arc ended, his care for her has grown even more, admitting that he couldn't bring himself to tell Hilda, while she was experiencing total memory loss, the truth about their situation simply because he saw how happy she was. But he seemed to be shy when people said Hilda was his wife.

When they had finally known the way to cure Hilda, which was a kiss from her prince charming, he had smashed the computer monitor with the keyboard, trying hard to pretend that the event had never occurred. It is unknown whether or not he was thinking the "prince charming" was him, given it was hinted Hilda had developed romantic feelings for him during her memory loss, despite the fact that it was actually Beelze.

She commonly calls him a "Damn Fool" though recently the term seems to have become less of an insult to something that could almost be considered a term of affection. After regaining her memories she claims not to remember anything from the time of her memory loss (though it's possible she is lying). Yet even after returning to normal she continues to call Oga "Tatsumi", and is the only one (excluding his family) Oga allows to call him that.

After saving her from Behemoth the two have grown much closer and more comfortable around each other. They can often be seen, willingly, spending their free time with each other.

Aoi Kunieda
Aoi has seen Hilda as a rival ever since the fight between the two of them. Aoi is seen being jealous of Hilda for being Oga's "wife", when it is just a misunderstanding of hers just like every other students in the Ishiyama Highschool. They started to get along with each other after the St. Ishiyama Arc. Though it almost immediately degenerated back into a firery rivalry when Hilda becomes jealous of Beels affection towards Aoi.

Lamia
Lamia has a great amount of respect for Hilda. Commenting on how beautiful Hilda is and called her as a breast idol because of the size her breasts are. she also refers to Hilda as "Hilda-nee-san/sama." When Hilda asked her for a favor on finding Lord En's whereabouts, Lamia did try her best to look for En. Along with Furuichi, and the other Ishiyama people.

Misaki Oga
Even though Misaki is just one of the sideline characters, Hilda's closeness to Misaki is very clear. At the beginning, Oga's family easily welcomed Hilda and Be'el into their family. As time passed by, Misaki grew fond of Hilda's presence. Hilda is very obedient to Misaki, thus, a perfect sister-in-law in the eyes of Misaki. When Hilda disappeared when Be'el got sick, Misaki kicked Oga out of the house and would not let him enter until he found her. She also comments on how Hilda and Oga berate each other as a normal couple would, and thus calls it their 'Love Quarrel'.

Yolda
Despite being sisters, Yolda has disliked Hilda for a very long time and hates being inferior and compared to her. What she hates the most, however, is that their appearances are remarkably similar, bordering identical, something Hilda reluctantly agrees with. Hilda still seems to care about Yolda, enough so to save her from prison before she overworks herself to death, claiming she doesn't need a reason to save her sister. It seems that the relationship between them is not publicly known by many people, only known by Oga, Furuchi, Izabella and Sachura. Even Lamia doesn't know about this till she was told by Izabella, Lamia stated that Hilda has never mentioned this to her.
