Growth cheats? Infinite magic power? The ability to utilize all archetypes? Whats 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 hadnt 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:
- Ambiguously Human: People within the in-universe who realize the real danger that Yogiri Takatou represents always come to the conclusion that he is not human, but something that pretends to be human.
- 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 using magic, the injuries caused by Yogiri proved to be 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.
- Cessation of Existence: This is the fate of all the people who ended up being killed by Yogiri.
- 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.
- 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.
- 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 and Tomochika 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.
- 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.
- 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.
- 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.
- 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.
- 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 youve summoned!? Its over already! This world is finished already! Dont screw around, damn it! If you want to die, die your own way! The world, me; dooooont drag us into it!
