Yogiri Takatou and Tomochika Dannoura

My Instant Death Ability is So Overpowered, No One in This Other World Stands a Chance Against started as a web novel written by Tsuyoshi Fujitaka before being published as a light novel in 2016. The light novel series was localized to English by Yen Press in 2020. The series shares the same universe, or rather multiverse, as My Big Sister Lives in a Fantasy World.

Growth cheats? Infinite magic power? The ability to utilize all archetypes? What’s the point if instant death ends everything with a single attack?

High school senior Yogiri Takatou was on a school field trip when he woke up to a dragon assaulting his sightseeing bus, with the only ones still on the bus being him and his female classmate, the panicking Tomochika Dannoura. Apparently the rest of his classmates had been given special powers by Sion, a woman who introduced herself as Sage, and escaped from the dragon, leaving those that hadn’t received any special powers behind as dragon bait.


And so Yogiri was thrown into a parallel universe full of danger, with no idea of what just happened. Likewise, Sion had no way of knowing just what kind of being she had summoned to her world.

My Instant Death Ability is So Overpowered, No One in This Other World Stands a Chance Against provides examples of:

  • Always a Bigger Fish: Malna and Rilna, two goddesses who considered themselves omnipotent and omniscient, discovered too late that Yogiri was not someone they should have provoked.
  • Ambiguously Human: In-Universe, whenever someone realizes the real danger that Yogiri Takatou represents, he always comes to the conclusion that he is not human, but something that pretends to be human.
  • A Million Is a Statistic: By volume 6, Yogiri has killed countless people, including over a million innocent people who were serving as backups vessels for a body-snatching wizard, without batting an eyelash. Then again, he's not human either.

  • And I Must Scream: Yogiri can inflict that fate on people when he tries to be creative with his power. He left a beast-man in a completely paralyzed state, unable to smell and see and also making him deaf enough to be unable to hear his own thoughts. When vampire Lain tried to heal the beastman by tearing one of his eyes out and growing a new one with magic, the new eye was still blind, suggesting that injuries caused by Yogiri are completely incurable.
  • Artificial Human: Shinozaki Ayaka, one of the students left to die on the bus, revealed himself to be an artificial human being, created to replace humanity in the event of mass extinction.
  • Blood Knight: Lord Raiza was so crazy to find a worthy opponent that he constantly ordered his sons to attack the villages in his territory and do all sorts of horrible things with the order to always leave survivors to make people hate him and come after him for revenge.
  • Born-Again Immortality: Yogiri is able to live a hundred years after the death of his current Incarnation, he will be reborn as a baby.
  • Cessation of Existence: This is the fate of all the people who ended up being killed by Yogiri.
  • Complete Immortality: Yogiri's true form is an invincible void that embodies the end of everything. It cannot be destroyed by anyone or anything perhaps barring his own Instant Death ability, which he would never use on himself anyway. It is eternal and cannot be erased by anything, granting him this.
  • Conditioned to Accept Horror:
    • The Gift from Sages causes the receiver to become more aggressive and cavalier about killing.
    • Mokomoko releases a seal on Tomochika, causing her to become more comfortable about death and killing, albeit not to the same aggressive extent as those with Gifts.
  • Cosmic Plaything: Rainier a person so unlucky that the goddess Vahanato manipulated him so that his bad luck would allow her to free her husband and then exterminate humanity.
  • Curb-Stomp Battle: Any fight that Yogiri gets involved in always ends with his opponent dying before they can do anything. Tomochika even complains at one point about the fact that he doesn't let his opponent finish his transformation.
  • Cursed Item: Before being taken away by the organization, Yogiri accidentally created a cursed video that killed anyone who watched it a while later the organization decided to destroy the video and any other copies for fear of the possibility of the video leaking onto the internet and causing the extinction of humanity. .
  • Death Seeker: The shadows that appear during the night around Yogiri are the souls of the Gods and Youkai who have grown tired of their immortality and seek to be killed by Yogiri.
  • The Dreaded: Before being teleported to other worlds, Yogiri was constantly monitored by organizations that were extremely terrified of its existence. When he disappeared, everyone who knew the truth about him sighed with relief that he was no longer on the planet.
  • Didn't See That Coming: Yukio Shiraishi did not really expect Asaka to be so competent in her work that Yogiri would become so attached to her.
  • Everyone Has Standards: Yogiri rarely showed any kind of empathy when using his power to kill someone, but even he took some satisfaction in killing the Children of Raiza because of the level of cruelty they enjoyed inflicting on innocent people.
  • Go Mad from the Revelation: When Aoi used her ability to see fate in Yogiri, she ended up losing her sanity when the only thing she saw was the end of everything that exists.
    Aoi: "It was a dead end. The inevitable destination of all fates, beyond which there was nothing. The end of all things in human form. An embodiment of nonexistence that would overcome all others, something that no one could ever hope to surpass. Before this thing, the machinations of Fate were nothing more than a crude joke."
  • Heroic Neutral: As long as he, Asaka, Tomochika, and anyone else he's close to are not the target, Yogiri doesn't care what happens around him.
  • Horrifying the Horror: The Heavenly Record Eater, a being that exists outside of reality responsible for devouring countless worlds, panicked when he realized that no matter what he did, he could not escape being killed by Yogiri in the next 10 seconds.
  • Meaningful Rename: Alpha Omega was Yogiri Takatou's original name while under the supervision of a secret organization, due to his ability to end anything. One of his caretakers, Asaka Takatou, named him Yogiri because she sees him as a human rather than an embodiment of death. Yogiri then takes her last name so that he has a full name, which signifies that she's his Parental Substitute.
  • Morph Weapon: After the protagonists negotiate with a Humongous Mecha, the latter gives Tomochika a shapeshifting material that can change into weapons or clothing on Mokomoko's command.
  • Mugging the Monster: Many of the deaths that happened in this series are due to the fact that nobody really knew what they were getting into when they decided to attack Yogiri and Tomochika. Since Yogiri's ability isn't one of that world's Gifts, it doesn't show up on his status, so he seems like a very easy target.
  • Mutually Assured Destruction: The organization that originally looked after Yogiri wanted to use him in order to give themselves a means to retaliate against other countries' nukes. However, there's not much they can do to really control him.
  • No-Sell: The Sages can bless town guards to negate the Gifts of the otherworlders. This blessing doesn't work against Yogiri's Instant Death ability, which isn't a Gift.
  • Not So Above It All: Tomochika usually comes off as more grounded and moral than her classmates, but her thought process can also be odd at times, such as when she's disappointed that Yogiri killed Masayuki before the latter could finish transforming.
  • Oh, Crap!: This was the reaction of the laboratory team when Yogiri, tired of waiting for Asaka Takatou to return from vacation, decided to leave the underground village where he was imprisoned to go look for her. Everyone quickly realized that the only reason he hadn't escaped yet was because he hadn't tried before.
  • One-Hit Kill: The story revolves around this. The protagonist has the ability to instantly kill anything with a thought, even gods, immortals, ghosts, and abstract or conceptual beings. Even beings with multiple layers of immortality and resistance to death manipulation can be killed by it.
  • Person of Mass Destruction: Yogiri's power allows him to kill anything, so he is careful to use his powers to not accidentally kill something important like gravity or space.
  • Pieces of God: The philosopher's stones that fuel the sages' powers are pieces of a goddess who, thanks to Yogiri and Tomochika's efforts to return home, is beginning to unite to regain her true form.
  • Poke in the Third Eye: The woman who was watching Yogiri on camera was very scared when he looked in her direction and asked her to open the door, the situation got worse when Yogiri started killing people who tried to stop her from opening the door.
  • Psychopathic Womanchild: The Ultimate Extermination God, despite being the Top Goddess of the multiverse, is surprisingly childish. She takes the form of a young girl, uses a very "edgy kid" type title, goes about erasing universes on a whim because of how much she likes to spread death and destruction like a kid playing a shoot'em up video game, is very arrogant and prideful due to her status as the top goddess of the multiverse and believes she can do whatever she wants without repercussions, throws a temper tantrum over being sealed away before condemning the universe she was previously sealed within as deserving to be erased simply because it played a part in her sealing, and, at the end, reverts to a raving coward whining about how unfair it is she gets killed by Yogiri since she's supposed to be completely invincible and immortal and the most powerful being in existence and how she never knew anything in existence could possibly destroy her.

  • Screw This, I'm Outta Here!: The witch Jet Black was one of the apostles sent to kill Yogiri, but unlike everyone else, she realized what she was getting into and wisely chose to listen to Yogiri's advice not to attack him.

  • Semantic Superpower: Yogiri's power doesn't just kill any 'one', it can kill any 'thing', including things that aren't actually alive.
  • Spanner in the Works: All the planning that Vahanato did to free her husband from his prison was completely useless due to the fact that he was accidentally killed by Yogiri.
  • Spider-Sense: Yogiri is able to know when something dangerous is about to happen through a black mist that gets stronger when closer to the danger in which it finds itself. It also allows him to know the location of people who demonstrate an intention to harm him.
  • Spirit Advisor: Tomochika is followed by the spirit of Mokomoko Dannoura, her ancestor. She prevented a Gift from being bestowed upon Tomochika, since that power turns its users into ruthless killers and could give the Sages leverage over the user. She takes it upon herself to teach Tomochika their family's martial arts to help the latter survive.
  • Spoiled Brat: The Ultimate Extermination God is an adult version of one, behaving like an entitled Psychopathic Womanchild who should have everything her way since she's the one true god of the multiverse.
  • Stalker Without a Crush: Ryouko Ninomiya and Carol S. Lane are government agents from the United States and Japan who were sent to the school to monitor Yogiri.
  • Story-Breaker Power: Yogiri's combination of instantly killing anything and sensing killing intent makes him nigh-impossible to defeat.
  • Trapped in Another World: Yogiri's class is sent to another world, though this new world has both magic and technology due to the influence of previous transmigrators. In a twist, Yogiri's home world is no stranger to the supernatural. My Big Sister Lives in a Fantasy World, the author's other work in the same setting, has werebeasts, vampires, aliens, mages, and people who are Immune to Fate.
  • Undignified Death: The Ultimate Extermination God goes from the most powerful being in the multiverse and the top god of the setting to a cowardly womanchild whining about how she is supposed to be invincible and unkillable as she's erased from existence by Yogiri. How the Mighty Have Fallen doesn't begin to describe it.
  • Weak, but Skilled: Tomochika Dannoura has no Gift or innate supernatural abilities, but is skilled in her family's martial arts.
  • What the Hell, Hero?: Sion is far from being considered a hero, but when she continues to plan actions against Yogiri, even when she is told that he is more dangerous than she thinks, Aoi tells her to stop before she makes the situation worse.
    Aoi: “You are! Because you summoned that! What are you doing! Do you know what you’ve summoned!? It’s over already! This world is finished already! Don’t screw around, damn it! If you want to die, die your own way! The world, me; dooooon’t drag us into it!”
