A girl and her motherfucking killer shark.
Killer Shark in Another World (Isekai Kuimetsu no Same) is a fantasy/comedy manga written and illustrated by Kuboken. It began serialization in the seinen magazine Comic Valkyrie in October 2020.After years of working her butt off at the most prestigious magic school in the land, Shiromi Rabuka Traf is a laughingstock at the bottom of her class, seen as moronic dead weight by peers and teachers alike. However, despite all the ridicule, she dreams of helping save the world from the vile demon army. Shiromi has one last chance to prove that she can summon anything more than a simple flower, and actually manages to do so. So, what did she get? A noble unicorn to ride into battle? An ancient, all-knowing dragon with the strength and skill to conquer all foes? A sexy demon to have a romantic, lewd adventure with?
Nope. It's a shark. A very hungry, killer shark. A very hungry, killer shark with the power of every B-Movie shark in existence. The good news? It likes Shiromi and only wants to make his new mistress happy. The bad news? This shark, dubbed Same, is a nigh-uncontrollable beast that hates practically everything that isn't Shiromi, meaning any infraction against her (no matter how minuscule) is an instant death sentence for anyone and anything in the immediate vicinity. After all her classmates get slaughtered, Shiromi finds herself forced to flee with the shark in tow, in hopes of still becoming the heroine she always dreamed of being. Oh, and figure out how to get Same to, y'know, not indiscriminately kill everything in its path.
This manga contains the following tropes:
- A Dog Named "Dog": "Same" is Japanese for "shark".
- Adults Are Useless: Not only Shiromi's teacher does not reprimand the other students who bullied her, she also immediately accused Shiromi of being a demon spy.
- Asshole Victim: Zig-zagged. Most of Same's victims are horrible jerks who take joy in tormenting others or flaunting their power. However, there are still moments when innocent bystanders become collateral during a fight.
- Berserk Button: Same's main trigger in early chapters is the usual trigger for evil sharks in schlocky horror movies (i.e., seeing lovey-dovey couples). As the story goes on, threatening or insulting Shiromi gets added to the list.
- Butt-Monkey: Shiromi is always the victim of the story's slapstick humor and receives zero respect from anyone. Even Same gets a frequent chuckle out of watching her suffer.
- Cluster F-Bomb: The work has quite a pottymouth.
- Combo Platter Powers: Same has all the powers of every movie shark. Among his abilities are becoming a three-headed sharktopus, flying on tornado winds and exploding with the force of an atomic bomb.
- Comedic Sociopathy: Same has no qualms in killing and devouring his foes... or almost anyone that isn't Shiromi.
- Death Seeker: Princess Nupi, thanks to the death of her mother and her father getting replaced by one of the demon generals.
- Deconstructive Parody : This is used for the whole fantasy genre manga and the current isekai genre mixed with a dash of Western B-movie goodness.
- Even Evil Has Loved Ones: Same might be a destructive, mass-murdering monster, but he legitimately cares for Shiromi and eventually is willing to tone things down a notch at her request. Sometimes. And if only barely.
- Gorn: There usually isn't a Gory Discretion Shot when people get mauled to bits and eaten alive by Same. And that can get very messy to say the least.
- Jerkass Gods: The goddess that caused Shiromi to summon Same absolutely loves Same's rampage and outright declares the world is his to eat and will ensure that there will be enough 'prey' for him.
- Jerkass Has a Point: Although the entire kingdom wants Shiromi dead, they are not wrong that she and her familiar have done nothing but cause mayhem across their land when there's a war going on. Granted Shiromi doesn't want to hurt anyone (that doesn't truly deserve it at least), but Same is just utterly uncontrollable once he gets going, harming both "friend" and foe.
- Kindhearted Simpleton: Shiromi. Nearly everyone sees her as a complete moron and want nothing to do with her, dismissing her at best and actively bullying her at worst. For her part, she is aware that she's seen as stupid and even agrees that without her "control" over Same she'd be The Load, but nevertheless is nothing but friendly and desires to become a hero regardless of all the insults and hate thrown at her and Same.
- Megalodon: During combat, Same becomes absolutely gigantic even by shark standards. Does become larger than that at one while fighting a giant octopus.
- Must Not Die a Virgin: Subverted. One student in Shiromi's school cries out that he doesn't want to die a virgin only for Same to grab him and eat him.
- Never Smile at a Crocodile: The Demon Army's giant crocodile monster.
- New Powers as the Plot Demands: Same pulls out different forms as need be, without any context as to why or how they exist. This includes flight or superjumps, horrific transformations, and coming back from the dead as a zombie shark.
- Nominal Hero: Deliberate example. Same is technically saving the world from the demons trying to kill everyone and rule over everything, but his only real motivation towards this is because that's the goal of his summoner Shiromi. And even that's superseded by literally anything else: triggering any classic shark or horror movie trope, harass Shiromi to the point where even he doesn't find it funny, and/or simply annoy him in any way, and he'll make sure you have a particularly messy death regardless of what side of the conflict you're on. Never mind the sheer collateral damage he causes even when his focus is squarely on the enemy.
- Power Levels: The first chapter has Shiromi state that Same is a level 893 monster. In comparison, the other summons range from level 5 to 23.
- Shout-Out: This manga references back to other shark films, both in the abilities Same showcases and the chapter titles.
- Chapter 1 references "3-Headed Shark Attack", "Jaws", and "Sharktopus"
- Chapter 3 references "House Shark"

- Slasher Smile: Same can somehow give a very sadistic grin whenever he slaughters his prey.
- Sleep-Mode Size: When not a gigantic monstrosity, Same turns into a smaller, Super-Deformed shark that's typically the size of a large dog and acts more like an affectionate pet towards Shiromi.
- Stock Light-Novel Hero: Take That! version, with Shiromi and Same regularly encountering isekai heroes with harems, complete with said women filling in the usual stereotypes. One such example being Talon, who acts like a laidback, humble hero until Same enters the picture, at which point it's clear the reason he acts like this is because he thought his abilities would protect him from any threat but take that away, he's just an idiotic brat. He's also not too broken up that several of his wives got killed by the shark.
- Threatening Shark: Same is a gigantic super shark with the powers of various movie sharks. While he's loyal to Shiromi, he's vicious to practically everyone else.
- Ungrateful Bastard: When a group of adventurers got captured by demons and are saved by Shiromi and Same, the only thing they could say was telling her that they could have gotten out of that situation on their own and threaten her not to report this.
- World's Strongest Man: Same is referred to in his biography as the "strongest motherfucker in the world".
