==Biography==
===Backstory===
In the past, Power used to be a savage and powerful devil that embodied the fear of blood. However though unknown circumstances she was forced to posses the corpses of a human girl however she continued to roams around other areas while being naked and filthy and only cared about killing several animals that she had encountered, including a giant bear. However, her life suddenly changed when she met with a rather malnourished cat as Power ended up naming her as Nyako. Initially wanting to fattening him up in order to eat him, Power suddenly formed a strong bond with Nyako before a Bat Devil intervenes with their relationship and kidnapped Nyako from her while using the poor kitty as a hostage in order to make Power cooperate with him to kidnap a human in order to regenerate his severed arm. As a result, Power then grew a seething hatred towards the Bat Devil. After she was captured by the Devil Hunter Organization and it's leader, Makima, Power decided to become a devil hunter to save Nyako and tried to lure a dim-witted human in order to be fed by the Bat Devil.
===Bat Devil Arc===
Introducing herself in Chapter 4, Makima decides to pair Power with Denji under the recommendation of Aki in order to experiment with the 4th section squad while expecting to get results from them. Denji then become ecstatic after getting paired with Power due to the prospect of being paired with female partner would give Denji an opportunity to touch a woman's breasts. During their small scale patrol, Power smacks Denji's head due to her boredom not killing somebody to satisfy her bloodshed. Unable to find any devils in their small scale patrol, Denji suddenly grew frustrated with Power suspecting that this is because of her fearsome reputation as a devil which scares other devils away.
However, after smelling a scent of blood, Power decides to track the whereabouts of the smell in which Denji attempts to stop her to no avail. After discovering the source of the smell coming from the Cucumber Devil in Nerima Station which was sealed by the civilian devil hunter, Power decides to commit an unnecessary carnage towards the devil to satiate her bloodlust which causes a huge explosion of blood as her body was soaked with it while she laughing maniacally for the mess that she had done.
Due to Power's recklessness, Makima then appears on the crime scene and reprimands both Denji and Power about the latter's actions which would potentially get them arrested while also reprimand Denji being unable to restrain Power's bloodlust. Deciding to evade responsibility, Power lied that her unnecessary carnage that she had caused is because Denji ordered her to do it which caused her and Denji having a small quarrel until Makima attempts to reconcile the two.
As the two take a bit of a break with them buying a juice, Power tells Denji about the Devil's natural instinct on hating humans and her affinity with cats due to what happened in the past. Deciding to use Denji as bait for the Bat Devil in order to save her cat, Power decides to offer Denji to participate in a little mission to save her cat while offering him a reward that he could touch her breasts after successfully rescuing her cat. This resulted in Denji agreeing on participating in Power's little mission and went into the location where the devil is hiding.
Arriving at the location, Denji suddenly becomes suspicious of Power's story about the devil would be scared if it saw Power and decides to use her cat as the hostage. This resulted in Power attempting to knock Denji out and give his body to the Bat Devil who was hiding in the house all along. As Denji's blood was drained by the Bat Devil, Power then reveals that the story about the devil would be scared if it saw Power was fabricated so that she could retrieve her cat back while looking down at humans being foolish as one of them manage to fell into Power's lies. However, due to the horrific appetite that he was given, the Bat Devil decides to eat Nyako as a punishment for Power.
Seeing her cat being eaten, Power then reminisces about her good old days with Nyako before being eaten by the devil and then suddenly become empathetic with Denji's situation of losing his pet, Pochita, after Pochita sacrificed himself to become Denji's heart. Because of this, Power decides to sacrifice herself by letting the bat devil eat her while the bat demon commenting how awful she tasted before flying to the city to find more predators as Denji clung to the bat demon in order to save Power so that he could feel the breasts she had promised Denji to touch as he saved her pet cat.
It was all successful in the end as he manages to save Power and Nyako despite her attempts to kill Denji for her own selfish desire and as a result, she tries to give Denji her promise to touch her breasts in the end. After the fight with the Leech Devil, Makima arranged Power to stay at Aki and Denji's apartment while spending her time acting like a problem child much to their dismay. After Denji encounters Power in the toilet, she then lets Denji squeezes her breast three times with the first showing that she uses breast pads and the other two squeezes is with her real breasts but Denji was left disappointed after seemingly fulfilling his dreams while Power decides to stick around after Nyako is rescued and unable to escape from Makima despite seemingly denouncing herself from the Devil Hunter business.
===Eternity Devil arc===
Returning again in Chapter 13, she alongside the other members of Division 4 were tasked to retrieve an important artifact about the Gun Devil fragment located in Hotel Morin as a devil was hiding inside it. At one point, it was revealed that both Power and Denji pulled a mischievous prank which made Aki infuriated. Encountering a lump of flesh that looks like a head in the 8th Floor, both Power and one of the members of Division 4, Himeno, captures and kills the head. After Himeno reveals her power so easily towards Power, she then teases Himeno by attempting to kill another Division 4 member, Kobeni, in order to make a point. Fortunately, Power was stopped by Himeno's ghost hand ability by choking her, which resulted on her mumbling about eating her.
As they were trapped on the 8th Floor thanks to the Devil hiding inside it, Denji suspected that it was Power's fault to kill the lump of flesh which Power tries too hard to refute by saying it was Denji's idea to kill the lump of flesh. Seeing that Kobeni fell into despair after getting trapped in the 8th floor as they will going to die, Power laughed at Kobeni's misery until one of the members of Division 4, Arai, yells at Power to calm her down.
Encountering the Devil whose body has grown larger, the devil then offers the hunters to make a contract with him by killing Denji and giving his body towards him. Power was seemingly on board with the idea so that she could escape and fulfill her selfish idea of winning the noble prize. However, Aki then reminded Power that she is unable to make a contract with another devil as Power is also a devil while also suggesting to not killing Denji much to Power's disappointment. Due to them being trapped in the 8th floor for so long, Power decides to eat all of the food the Division 4 members put on the bed while lying about it to save her own skin. After the Devil was defeated, Power then joins the other Devil Hunter members going to a certain bar in order to celebrate their victory with drinking.

In Chapter 23, as a gunshot was heard during the devil hunter's break at the ramen store, Power was oblivious about it and dismissed it as a sound of Taiko Box. However, she shows her heroic act when she attempts to treat Himeno well as she bleeds during the Devil Hunter's fight against Samurai Sword to the point Power suggested Aki to bring her to the hospital to no avail. In Chapter 29 however, it was revealed that Power ran away from the fight when the going gets tough while trying to justify her cowardice by saying she got hungry.
Due to how powerful Samurai Sword and his accomplice, Akane Sawatari, is, Makima then arranges both Denji and Power to be tutored by the strongest devil hunter, Kishibe, in order to whip them up into shape. Because they were kept brutally knocked out by Kishibe several times, Power then comes with an idea to beat Kishibe if he was drunk so that they could murder him and Denji was on board with Power's idea. With Power's ideas, Power attempts to attack Kishibe first by aiming a spear made by her blood to his head to no avail. However, in the end, both Power and Denji were successful in their training and were assigned to do a small-scale raid in the Samurai Sword's headquarters.
As their small-scale raid begins to capture Samurai Sword and Akane, Power ate one of the Zombies' hands which disgusted Denji as Power retorted by saying pigs, lambs and humans are the same for being meat. During their fight against another wave of Zombies, Power ignores Denji's advice to not make a noise and then tries to finish the battle quickly in order to indulge in the bloodshed that ensues. After both Samurai Sword and Akane were defeated, it was revealed that Power grew other horns and punched Denji after waking up from his sleep as he was babbling about something. As Denji met with Makima, the latter then tells Denji about Power used to have her blood drained periodically in order to prevent her from becoming worse in terms of appearance and personality and as a result, Makima then decides to swap Power's place with the Shark Devil, Beam, much to Denji's dismay.

It was revealed that the Devil Hunters themselves were using Denji as bait to lure all of the assassins in order to finish defeat them and during Denji and Power's patrolling session, Power feels disappointed because she feels that she doesn't get a reward from all of this unlike Denji who got motivated to go to Enoshima and she wants to suck out all human blood until they die. As a result, Aki then arranges a reward for Power by letting her suck Denji's blood much to Denji's dismay.
When Power saw Kobeni's new car during the Devil Hunter's meeting with the surviving Kyoto Devil Hunter who was ambushed by the assassins, Yutaro Kurose, Power then decides to ride Kobeni's new car because she was bored walking. As a result of her reckless driving, she accidentally killed said Devil Hunter which resulted in him being revealed to be one of [the Three Brothers assassins that tried to kill Denji.

However, in next chapters, Power calms down a bit and acts like her older self at first when Denji and co. went into Hokkaido. Although it is stated by Aki that her behavior shaped a bit after going to Hokkaido. This was true as next chapters, Power was truly toned down a bit in terms of behavior. When the Gun Devil runs away from Makima's attack at the beach, Denji tells Power to escape the house with Nyako following Makima's orders through the phone. After he opens the door and reveals that the Devil had possessed Aki's corpse, Denji is gunned down.

Power seemingly meets her end in Chapter 81 as she tries to bring Denji a birthday cake to Makima's apartment until she kills her with her psychic finger gun power in cold blood.
However, Power was then resurrected with the help of Pochita requesting Denji to be revived as he encountered her laying dormant in Denji's inner body as it was revealed he sucks some blood from her with Pochita offers her body to be eaten by Power to become stronger in which Power accepts, stating that Denji is her friend. After being resurrected, she then manages to impale Makima and her slaves as Makima retaliates as she attempts to attack her with the 100 years old weapon.
