Power/History

Intro arc
As Makima was telling Denji that she would pair him with someone to patrol together and do small-scale missions, Power showed up telling Denji to grovel before her and introducing herself. She asked him if he was her new partner, and noticing that she was female, Denji got excited to work with her.

Bat Devil arc
Denji and Power go patrolling on the rooftops with Power rapidly becoming bored and striking Denji on the head as she demands blood. Denji thinks to himself that Power is crazy and wonders as to how he will manage to touch her boobs. After a while Denji ends up frustrated that there are no devil around and Power boasts that it is likely due to her history as being a fearsome devil that is scaring all the other devils away.

Suddenly Power smells the scent of blood and races off across the rooftops in pursuit of battle with Denji following behind her. She leaps off of the roof and creates an enormous hammer made of her own blood which is released from her wrist. She slams it down onto a Sea Cucumber Devil which had a civilian devil hunter trapped in a nearby phone-booth causing an explosion of blood which soaks her entire body. Power proudly proclaims that the glory is hers and laughs manically.

Makima arrives to the scene and chastises Power for killing the Sea Cucumber Devil even though another devil hunter had already engaged it. She also chastises Denji for letting Power get out of control. After Makima calls her excitable and possibly unsuited for work as a devil hunter Power begins to freak out and accuses Denji of ordering her to kill the devil. Denji indignantly rejects her lies and the two argue back and forth until Makima asks them to be quiet.

Power and Denji go back to patrolling with Power staring at the contents of a vending machine and noticing a cat nearby. She tells Denji that she only gets along with cats and that she hates humans due to her instincts as a devil. She confesses that she hates devils too since one of them stole her pet Meowy from her and that she would do anything in order to get him back. Denji claims not to understand being able to go so far for just a cat but would understand it if he was trying to touch some boobs or help a dog. Power makes Denji an offer that if he gets Meowy back for her, she'll let him touch her chest. Denji suddenly starts cursing the devil who kidnapped her cat and enthusiastically agrees to kill the devil for her.

Denji gets permission for him and Power to go out an outing and they take the tram. Power tells Denji that only he'll be able to fight the devil as it'll use Meowy as a hostage against her if it sees her. Denji looks at her skeptically but decides to go along with it after focusing on her chest. He tries empathizing with her by talking about Pochita and how that even if he is gone, Pochita is still inside him. Power rudely rebuffs his words saying that Pochita is just dead which annoys Denji.

Power leads Denji to the house where the devil is, but accidentally reveals that was earlier story was just a cover. Denji catches on and tries to attack her but she knocks him out. Power drags Denji into the house and reveals that her intention was to bring a human to the Bat Devil in exchange for Meowy's freedom. The Bat Devil picks up Denji and drains his blood to regenerate his arm. As Denji is dropped the floor, Power looks down on him and states that humans really are foolish since he was tricked by her.

Power demands that the Bat Devil return Meowy to her but the Bat Devil complains about drinking Denji's blood and finds it disgusting. As punishment towards Power the Bat Devil eats Meowy. Power reminisces on how she met Meowy and she empathizes briefly with Denji losing Pochita, before the Bat Devil picks her up and swallows her whole. The Bat Devil comments that she tastes disgusting before flying towards the city with Denji clinging to him, demanding the return of the boobs that were promised to him.

After Denji kills the Bat Devil, he saves Power and Meowy from his stomach. Power asks him why he went so far to rescue her even after she decieved him, and Denji makes a groping motion in the air. Power comments that his motives are foolish, but since Meowy lived, she'll let him feel her chest. As he celebrates the Leech Devil attacks them while they are both weakened and eats Denji's arm. Denji asks Power if she can move and she responds that she cannot, forcing Denji to fight though he is unable to fully transform due to a lack of blood. The Leech Devil indicates that she'd let Denji go, but when she states that she'll kill Power and Meowy, Denji refuses to leave and leaps into battle.

Power watches in shock at how far Denji would go just to touch a pair of breasts. She comments that his bloodthirsty and reckless way of fighting makes him look like a demon. Just as Denji is about to be defeated and eaten by the Leech Devil, Aki saves them by using his Fox Devil. Aki states that Denji and Power are to be debriefed and that Meowy will be taken to a veterinary hospital for a check-up.

At the hospital Aki questions Denji about Power and if she really tried to get him killed but Denji plays dumb to cover for Power. Outside Denji's hospital room a handcuffed power is being watched over by Himeno and demands to be released now that her alibi checks out. Aki decides to release her since she is just a tool to use against the devils and he has no plans on getting friendly with her.

Later Power shows up at Aki's and Denji's apartment and announces that she is living with them now on Makima's orders, much to their dismay. Power proves to be a nightmare to live with as she is picky with her food, refuses to bathe and refuses to flush the toilet. Just as Denji is cleaning the toilet for her, she shows up and offers to fulfil her promise to let Denji feel her boobs causing Denji to see her as being like an angel.

Power offers Denji three squeezes, in exchange for saving Meowy, killing the Bat Devil and covering for her in front of Aki. Denji immediately accepts her offer and squeezes her breasts only to discover that Power is wearing breast pads which fall out. Power allows Denji to continue touching her real breasts which she responds to positively but Denji is left massively disappointed. Power eventually stops Denji after the third squeeze, seemingly embarassed. She states that there is no reason for her to be a devil hunter since Meowy has been rescued but she'll do Denji a favor and stick around, since she still can't get away from Makima.

Power is selected as part of a six-man team to enter the Morino Hotel and track down the devil within which has also eaten a piece of the Gun Devil.

Eternity Devil arc
Power was part of the squad sent to deal with the Devil reported at the Morino Hotel, along with Denji, Aki, Himeno, Kobeni and Arai. Upon arrival she and Denji weren't taking the job seriously, asking to be handed the Gun Devil fragment because it "seems cool" and reacting belligerently when asked to be more proper on the job, but Aki calms them down with gum. Hearing Arai's mistrust of her for being a fiend, she complains to which Aki responds that they have no right - she wonders if Aki is in a bad mood because of a prank she and Denji pulled that morning.

As the group headed inside, the Eternity Devil's avatar appeared and Power eagerly went to kill it while Himeno held it in place with the Ghost Devil's hand, Power declaring herself to having scared the devil so much it started floating. When Himeno mentions how knowing their abilities could help in teamwork, Power threatens Kobeni with a blood knife, asking what she would do if she said she was going to kill her, whereupon Himeno strangles her with the Ghost Devil's hand, which Power cant push off due to it being intangible. Himeno declares she can kill Power is she acts up, so Power agrees to behave. As the group discovers they've been trapped in the 8th floor by the Eternity Devil, she gets distracted and is talking with Denji about dinner, then laughs at Kobeni's panic about the situation. After Denji wakes up from his nap, Himeno mentions Power is acting weird since she's talking about winning the Nobel Prize so she can become Prime Minister and impose a 100% sales tax, to which Denji replies that this is normal behavior for her.

Once the Eternity Devil's avatar offers a contract to let everyone go free in exchange for Denji, she's willing to accept, but cant perform a contract due to being a fiend - she tries to  strikeconversation with him normally, but he rejects her. While everyone is considering their options, she sneaks away and eats the groups' rations, but calmly denies it - even as Kobeni accuses her and Arai of conspiring against them. After Kobeni accidentally stabs Aki, she reluctantly helps stop the bleeding with her ability, though she notes its much harder to control other people's blood Once Denji engages the Eternity Devil, she comments that he might run out of blood before beating it but when he discovers his own blood consumption ability, she has nothing to do but wait for the three days it takes Denji to whittle down the Eternity Devil, after which she and the rest of the group left the Hotel.

Katana Man arc
Denji, Aki, Himeno Power eat Ramen at a local restaurant, when they start to hear gunshots in the background, which Power mistakenly believes to be drumbeats. A random man at the restaurant approaches the group, asking them how they can wolve down the ramen despite how awful it tastes. He starts to talk about how eating the same stuff repeatedly makes you lose your sense of taste. He starts talking about his father, who was a Yakuza, but a ”just Yakuza” who would use the money he earned with drug dealing for buying his son expensive food. He reveals himself to be the son of the Yakzuza-boss Denji used to work for. Shortly afterwards he draws a gun and starts firing at Denji, Aki and Himeno. Thanks to her supernatural reflexes, Power reacts quick, punching the attacker against the chin, forcing him to drop his gun. Aki manages to recover and uses his contract to get the attacker eaten by the Fox devil. However, the attacker manages to cut himself free reveling himself to be a Devil-Hybrid.

Aki starts to fight to fight the Katana devil with his secret sword, which to powers surprise turns out to be a giant nail, while power stays behind looking after the injured Himeno. After the Katana-man is apparently killed by the swords curse, after getting stabbed with it three times, Aki turn back to Power asking her about Himenos status, Power respond that they should take her to the hospital. Their conversation is interrupted by the appearance of a mysterious woman, who reveals herself as an ally of the attacker by reviewing the Katana man. The Katana man attacks Aki slashing his chest open

Himeno tells Power to ignore her and help Aki, but Power is too scared of the Katana Mans abilities, stating that she couldn’t even see him move when he cut Aki. Himeno uses her contract with Ghost-Devil to offer all her body to use all of the ghost-Devils body. The Ghost attacks the Katana man but is forced retread when the mysterious woman summons the snake-devil to assist him, thought before disappearing the ghost manages to pull Denjis Chainsaw trigger.

Power remains in the Background while Denji fights the Katana man. Still too scared of Katana man, she makes no efforts to help Denji not even after he is defeated and dragged away by the enemy. Denji only survives due to the sudden appearance of Kobeni and Makimas telekinetic abilities

Denji and Power visit the still unconscious Aki in hospital. While being their Power starts a fight with denji over the remaining Apples in the fruit basket. Denji accuses her of having run away from the where opan argues that she didn’t run she simply got hungry and left. While the two have their quarrel Aki awakes from Coma. After a short conversation, Denji and Power leave the hospital as they are summoned by Makima. They meet her at Graveyard she explains to them that in the wake of the recent events, both Denji and Power will need to improve their fighting abilities and introduces them to their new teacher. Before Makima can reveal his name, the teacher asks them three questions: „What do you think when your comrades die?” Which power answers with “I thought, they were dead,”

"Do you want get revenge on the enemy?" Denji answers that he doesn’t care for such a gloomy idea and Power agrees

"Do you consider yourself allies of humans or devils?" which she answers with "which-ever one is winning"

The man congratulates the two for giving the perfect answers. He tells Makima to leave introduces himself as a Devil hunter of the elite first Division. He tells them that he wrapped his head around how to train them best and came the conclusion, that since he is the best Devil Hunter, the best Devils would be the one that manage to kill him. The two are given their first chance to kill him, Power slices her wrist to create a blood, which she hands over to Denji, however the old man easily defeats them by stabbing Denji repeatedly and slicing Powers throat open. After beating their asses for more than twenty times, the old man calls it a day leaves the two for tomorrow. Frustrated by their, losses, Power considers running away together with Denji, but he reminds her that the Burau will find and kill them. Power argues that instead attacking him with brute force as they did before, they should use the brains and think more tactical.

The next day Power and Denji try to realize their "super genius" strategy that they developed last night. They don’t appear to the training, which forces the old man to search them out at their apartment. Power can smell him before he can knock at the door and attacks him Blood-Spear. The man dodges the attack with ease, however Power has anticipated that move and attacks him with Blood-Spears spawned from blood filled bottles that she hid in the ceiling. Unimpressed the old man dodges again, denji tries to use the momentum to sneak behind him and attacks him with an axe the old man quickly turns around and kicks Denji in the face. Th old man reveals that there were two reasons why they lost, the first being that Denji couldn’t anticipate his attack the second one is that fighting like that causes power to lose too much blood, which puts her into a paralyzing state of anemia.

After constantly improving their skills, the old man tells them that one training session per week will be enough from now on. He also tells them that they gonna attend a real mission the following day, they gonna must catch the katana-Man and the snake lady that killed Himeno, if they fail, they gonna be disposed and must fight their master in a real battle.

After entering the Katana Mans hideout, Power and Denji must fight themselves a way threw an army of Zombies that the Yakuzas called as reinforcement by using their contract with the Zombie Devil to reach for an elevator. After arriving at the elevator, Power eats the arm of a Zombie that she picked up as snack for in between. Denji shames her for eating human meat, Power responds the meat is meat it doesn’t matter if its from humans or animals. The elevator doors open at the next level revealing another Flore full of undead. Denji tells Power to stay calm and silent as the Zombies have not yet noticed them, but in accord to her arrogant and childish nature, Power ignores him and loudly charges at the enemy using two swords she made from her blood. She continues to slaughter the zombies’ shouting praises about herself while Denji uses the elevator to reach the new level

After Denjis victory over the Katana Man, the squad returns to their apartment to celebrate their victory. Waking up the next morning Denji notices that powers has changed, her Horns have grown larger, and she developed as second more curved pair horns beneath her main horns. Makima comes in and explains that powers condition is caused by her drinking too much blood during her fight with the zombies, and that power gets her blood drained regularly in order to stop her from becoming more powerful, arrogant and childish than the already is.

Bomb Girl arc
After getting her blood drained Power makes a reappearance by tracking Denji's scent to the coffee shop where he was waiting for Reze. She loudly announces her entrance through the door and sits next to Denji, noticing the flowers he had bought for Reze. When she inquires about them, Denji chooses to eat the flowers rather than give them to Power.

Control Devil arc
At her apartment, Makima reveals to Denji that she invited Power over and instructs him to open the door so she can kill Power. Denji is disturbed by this but complies with her order and opens the door to see Power outside with a birthday cake for him. Makima then brutally kills Power by pointing a finger at her and blasting her torso away, leaving her legs and head remaining.

Her head and legs are later seen in the hallway alongside the rest of the followers.

Following the events of Makima's onslaught against Denji, Power was suddenly awoken by Pochita and asks her to save Denji. Rather confused, she was convinced that she had died from the hands of Makima prior, but Pochita reassures her that her consciousness had merely been transferred to Denji, due to her request of making him drink her blood. Pochita warns Power that even if she is a blood devil, she will soon disappear if Makima continues to kill Denji. The devil then offers itself as a sacrifice for Power to eat, so she can be revived and help Denji. Pochita asks her once again if she wants to save its owner, and to that, she confidently accepts, saying that Denji is her buddy, after all.

A few moments later, the newly revived Power emerges from Denji's body, with her appearance completely changed into a more demon-like look, while also wearing a mask resembling to that of Pochita. With Makima confused, she attacks Power, but is immediately retaliated by an even stronger attack, thanks to the power boost that she had gotten from consuming Pochita. Makima then subdues her with her army of zombies, and shoots her right arm off, asking Power as to how she was still alive even though she had already been killed before. Power then tries to grab Denji's body and escape, but her attempt was immediately shut down when Makima had shot her in the back, realizing that she had no chances of escaping. Makima proceeds to offer her a chance to give Denji's body in exchange of making herself Makima's pet again, to which Power happily proceeding to do so with no second thought.

After a moment of silence however, Power remembered the bond that she had made with Denji, and had instead, attacked Makima and ran away, while questioning herself as to why she disobeyed Makima's order as she realized that she cannot beat her. Makima then orders her army of zombies to chase after her, and while most of the zombies had managed to injure Power, she eventually goes into a tight alleyway. While remembering her ideology of all life being unequally important, including hers, and that a person's death is nothing to be sad about, Power proclaimed that Denji is the only exception, as he was her very first friend.

Having managed to escape Makima and her puppets, Power and Denji return to their normal form, and find themselves inside of a dumpster container. Seeing as how Denji was alive and well, Power proceeded to hug him and say that she came to save him, to which Denji replied that he had already gotten to do everything that he wanted to do in his life, and that it was okay for him to die permanently. Power then calls him an idiot and a wimp for trying to give up, and offers him her blood and make a contract to help in defeating Makima. Before disappearing, Power tells Denji that even if a devil dies, it'll always just be revived in Hell and be reincarnated in the surface world again. She tells him that when that happens to her, she will lose all of her memory of Denji and their time together, and that the next time they meet, they will be enemies. Power makes one final request for Denji to find the blood devil again and turn it back into the old Power, so that they can continue to be buddies again. When Denji finally woke up, her body had disappeared and became a part of his body. Denji himself then mourns for her.

Current Arc
During Denji's date with Asa in an aquarium, the reincarnated Eternity Devil appears trapping Denji again on-site. During the hours of imprisonment, he remarks that while Asa's speeches are boring, her actions are interesting to watch and concludes that she is a fun person. This compliment makes Asa blush, and prompts her to enthusiastically proclaim that she is a fun and charming person and that Denji has a good eye for noticing. Denji goes on to say that Asa's enthusiastic attitude reminds him of an old friend, implying that friend to be Power.
