The boy, totally unaware of what had been about to happen to him, recognised the figure as Chainsaw Man.
The figure launched into a little speech, and the mysterious devil above them even offered to save him. He spoke about fighting with the power of justice, and between that and the look of him, something about the whole thing did not quite sit right.
The bandaged kid, stunned by Chainsaw Man and his demonic appearance, tried to defend the girl next to him by saying that she had only been joking around earlier.
Not believing the boy, Justice left his vantage point and demanded that the girl show him what she had.
The unknown devil girl threw a punch, and Justice tore straight through her. With a flurry of slashes, he cut her into a bunch of pieces.
Unable to get over how easy that had been, the fake Chainsaw Man questioned whether she had really been the right girl. Trying to justify what he had done, he stated that he had never been steered wrong. He was Chainsaw Man, the devil-killing avatar of justice. It was his job to stop the prophecies. And that girl had been an evil devil, partially responsible for the destruction.
The student, on the other hand, unable to believe what had just happened, was understandably furious that Chainsaw Man had seemingly killed a regular student.
Right as the two of them began arguing over the morality of the situation, the student noticed the girl's severed forearm latch itself onto his leg. Justice screamed out, telling him to get it off him, but it was already too late. Moments later, the devil activated her ability and drained the life out of the boy's body. Her limbs shot back across the room and connected, bringing the fallen horseman back from the brink of death.
Quickly running some calculations, the devil could tell that, judging by his fighting style and the way he carried himself, he had to be a close-range fighter only. Sticking three fingers forward, she told him that he would be saved in three seconds.
Not giving her that time, the fake launched himself in and completely eviscerated the horseman.
The head, which had been flung off and had landed somewhere nearby, then attempted to bribe the fake Chainsaw Man with a mere two thousand yen. Obviously this failed, since he did not believe in money. Not caring about conspiracy theories either, she claimed that there were lives to be saved here.
The fake assumed that she meant she wanted to save people through death in order to ease their suffering. Feeling like he had seen it all, he elaborated on why people went on living in this hellish environment. It was simply because the world was full of hope. Chainsaw Man himself had come back from hell in order to protect mankind's hope, and to drag worthless beings like her back down to hell where they belonged.
Calling out her true nature, he told her that he knew righteous words meant nothing to something like her.
Suddenly coming to a horrifying realisation of her own, the girl immediately responded by regenerating her body and staring down the so-called Chainsaw Man.
Looking at the ants on the ground, the fake asked whether she had absorbed the lives of those ants. She agreed that she had. After all, she was the one who absorbed life and saved people from their suffering through death.
Finally giving the fake Chainsaw Man a proper introduction, the girl said that she was one of the four horsemen feared by humans and devils alike. Her name was the Famine Devil, but she preferred to be called Famine.
The fake stood there utterly confused, asking whether she had just said Fami.
Famine, she repeated.
Still physically unable to wrap his head around what had happened, he straight up asked whether she was not the Death Devil.
Then they fell. A sudden, universal force sent both Fami and Justice dropping straight through into the floor below.
Appearing next to the new Fami, the great chef herself, the Falling Devil, asked, "What's on the menu today?"
The true Death Devil, who had been pretending to be Fami this entire time, someone who had faked them all out for years, let the chef make the decision. Several bystanders and animals were sacrificed for it. Falling dished up a blood-sautéed human and giraffe.
Realising that the faker of fakes had himself been faked out, the fake Chainsaw Man asked the Death Devil whether they really were Death.
In answer, Death began taking off her school uniform. Turning to those in front of her, she revealed that even after she had disposed of all of her organs, she still could not die.
Standing there, the Falling Devil told her boss that the two of them were probably staring at her exposed underwear.
Death answered her sister by explaining that even if she could die, another Death Devil — one who would likely be less sympathetic to humans than she was — would take her place and destroy humanity.
The fake Chainsaw Man posed the idea that she simply live somewhere else, quietly. Sadly, she stated that this was not possible. On the day of the prophecy, for one reason or another, mankind's fear of death would reach its peak. In that moment, powers dormant inside her would activate, even if she were just sound asleep, doing nothing at all.
Knowing how to get around this, the real Famine suggested that she get eaten by Chainsaw Man, saving everyone by erasing the concept of death.
Death paused and genuinely considered it for a moment. Then she told the other two that if they wanted to help protect humanity, they would have to work with her.
The duo accepted on the spot.
Not trying to get duped, though, Death rescinded the previous offer, since now she was going to eat them instead. Slapping her hands together in preparation to smash back this meal, Death summoned a murder of crows, which settled on a nearby railing.
Pulling out her cutlery, Death then proceeded to devour both the Justice and the Famine Devils.
Watching the murder of crows fly away from the scene, Falling asked her boss how the meal had been. Death told her it had been straight-up garbage.
