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 laughing stock 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 to 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 does Shiromi's teacher not reprimand the other students who bullied her, but she also immediately accuses Shiromi of being a demon spy once Same brutally devours said students.
- Affably Evil: The Goddess comes off as nicer, and more polite to the story's heroine than most everyone whom they meet. She's also revealed to be a batshit insane Nightmare Fetishist, one who purposely arranged for Shiromi to bring Same into her world. Just so he could grow by devouring it at his wilful leisure.
- Asshole Victim: Zig-zagged. Most of Same's victims are horrible jerks who take joy in tormenting others or flaunting their power over weaker subjects. However, there are still moments when innocent bystanders become collateral during a fight.
- Assassin Outclassin': Same, a revealed-to-be superior evolved being, often outmatches the latest Showy Invincible Hero and their groupies in battles during his and Shiromi's outings.
- 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.
- Blatant Lies:
- Most people who complain about the damage caused by Shiromi's familiar often take liberties in explaining how it occurred.
- The summoner instructor never liked Shiromi, but in her video memoir, she embellishes the heroic natures of her more difficult students after she is carted off to prison.
- The most glaringly guilty of this are the Ungrateful Townsfolk who tried to sell her out to demons as they'd done to other outsiders in the past. Only to lie at her public execution about how she threatened them with death at her summons jaws if they didn't give in to her demands.
- 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.
- 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.
- Deconstructive Parody: This is used for the whole fantasy genre 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.
- Fake Ultimate Hero: The series has many instances of arrogant and vile individuals who proclaim heroism yet act like schoolchildren in their mistreatment of those who are generally kind to them. A party of heroes prioritizes their public image over showing gratitude for having their lives saved. An actual transmigrator who seems to be more interested in pursuing harems than focusing on improving their abilities and teamwork. The list goes on from there.
- Fluffy the Terrible: Same only looks like a cute and cuddly oversized guppie while partnered with his Summoner. In truth, his actual size could rival that of a humpback whale, leveling with the ferocity of a Destructive Savior to match.
- Good Is Not Nice: Shiromi is a true blue sweetheart with a valorous spirit to a T. It is everybody else with the claim to heroism or who is an actual so-called samaritan that is a Hero with an F in Good.
- 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.
- Hero with an F in Good: Shiromi really does try her best to be good and do right, it's just that everyone around her often badmouths or attempts to drag her down for their own perverse, selfish, or self-righteous intentions. It doesn't help the fact that her travel buddy is an Ax-Crazy, gluttonous murder machine who causes far more collateral damage than his opponent does.
- Humans Are Bastards:
- The story portrays the majority of its characters, save the protagonist, as unpleasant, aggressive, immoral, haughty, deceitful, and manipulative individuals who are no better than their enemies. Such characters serve only to emphasize the exceptional morality and virtue of the heroine, Shiromi.
- The teacher is a strict, overbearing, scumbag with favoritism issues. Secretly and openly slighting Shiromi as a fool with no talent and a traitorous spy after summoning Same, she also slaps Shiromi multiple times.
- A Brave and his party were nothing more than a bunch of Failure Hero AttentionWhores. Who, after having been captured by demons, threatened Shiromi despite her going out of her way to rescue them from the enemy's clutches.
- Some townsfolk tried to have Shiromi sold off into slavery to the demons; revealing themselves as actual traitors, only to blame her for everything going wrong when their town was destroyed.
- Innocently Insensitive: Some denizens of a magic country greet Shiromi more openly and warmly than others. But due to their high off their ass society, they still slate her with derogatory terms like Country Bumpkin and the like. This inevitably gets their respective left hands chewed off by Same in response.
- 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 barring few exceptions sees her as a complete moron and wants 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 is nothing but friendly and desires to become a hero regardless of all the insults and hate thrown at her and Same.
- Laser-Guided Karma: Directed at almost everyone who either often harms or insults Shiromi. More often than not, everybody Same directly harms or indirectly ruins all have it coming. See Humans are Bastards above.
- MadGodess: The deity who put it into Shiromi's mind to summon Same, comes off as rather unhinged while marveling at her champion's murderous rampage from behind the scenes. She literally gave her world to him in order to grow and feed and evolve.
- Never My Fault: Most people blame Shiromi and Same for their failed lives imploding on themselves. Never mind the fact they keep making Deals With The Devil or continually piss off what is essentially a horror/thriller-themed Ultimate Life Form, who takes very poorly to anyone insulting its companion.
- 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, harassing Shiromi to the point where even he doesn't find it funny, and/or simply annoying 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.
- Only Friend: Same is basically this to Shiromi, though she is occasionally joined by travel companions (most of which tolerate her moreso than like her). While on one hand, it is a bit sad that a bloodthirsty, metamorphic apex predator with Big Bad Friend tendencies matched only by his seemingly limitless appetite is her only true ally, given all the people whom the two know or tend to meet, it's more of a Jean Paul Satre phrase enactment.
- Power Copying: In Ch. 8, Mister Exposition explains how Same attains its different forms and newfound power levels. He possesses the ability to visually or experientially emulate the facilities of almost any enemy he has to fight. Taking their abilities and making derivative variations of his own for personal use.
- 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"
- Chapter 4 references "The Meg"
- Chapter 5 references "Sharknado"
- Chapter 6 references "Deep Blue Sea", "Ghost Rider (2007)" (non-shark film), and "Mega Shark vs. Crocosaurus"
- Chapter 8 references "Saltwater: Atomic Shark"
- Chapter 9 references "Terminator 2: Judgment Day" (non-shark film)
- Chapter 11 references "Sharknado 3: Oh Hell No!"
- Chapter 12 references "Mega Shark vs. Giant Octopus"
- Chapter 15 references "47 Meters Down: Uncaged"
- Chapter 18 references "Independence Day" (non-shark film)
- Self-Inflicted Hell: The onset of the demon lord only becomes an extinction-level crisis for humanity, because human prejudice kicked the current ruler of all demons to go on the warpath in defense of his people. The Jerkass tendencies of all Shiromi's naysayers practically left themselves in the mess of life & death battles they're trapped in currently.
- 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.
- Spice Up the Subtitles: The most common fan translation of the manga is extremely profane, with just about every character but Shiromi swearing constantly. The narrator is particularly foul-mouthed.
- Stock Light-Novel Hero: A Take That! mixed with inverse version, with Same himself being the reverse appliance. Shiromi and Same regularly encounter isekai heroes with harems, complete with women filling in the usual stereotypes. One such example is Talon, who acts like a laid-back, humble hero until Same enters the picture, at which point it's clear the reason he acts like this is that he thought his abilities would protect him from any threat but without them he's just an idiotic brat. He's also not too broken up by the fact that several of his wives got killed by the shark.
- Straw Hypocrite: The excessive methods a lot of the stupid jerks in the story use in order to paint Shiromi either as incompetent or a menace. Goes to show the lengths these schmuks will go to ignore or cover their own repulsiveness. What passes for heroes are all stuck-up, volatile, oversexed glory hogs who care less about saving people and more about throwing their weight around like boisterous anal sores.
- Super-Deformed: Same's default setting for regular travel or local interaction. He's no less dangerous in that form of course, as a great many unlucky (if albeit oversexed) types he tends to meet can suffice.
- 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 only to be saved by Shiromi and Same, the only thing they could say was tell her that they could have gotten out of that situation on their own and threaten her not to report this.
- Ungrateful Townsfolk: The common mook treats the main character badly and goes out of their way to be inhumane. Shiromi was offered as a slave to demons by the first village she encountered, who then got mad at her for the consequences their conniving entailed.
- With Friends Like These...: Even though Shiromi's summoned familiar Same means well, he's not exactly the best company to keep around.
- World of Jerkass: Practically everyone in the kingdom (and beyond it) are all self-serving assholes, except for Nice Guy Shiromi.
- World's Strongest Man: Same is referred to in his biography as the "strongest motherfucker in the world".
