But one day, without any reason, Kurono was attacked by a mysterious headache while in the literature clubroom and fainted. When he finally awoke.......Swords & magic, filled with monsters, an orthodox different world summoning.
Associated tropes
- Bad Is Good and Good Is Bad: Enslavement, torture, medical experiments, and bloody genocide is "good" and "monsters" wanting to live their lives in peace is so "bad" they deserve to have their bodies mutilated and whatever is "human" about them, crucified.
- Bait the Dog: From the very end of chapter 2 to the very end of chapter 8, it looks like Korono, who managed to escape the "White God Church," can live a peaceful life in the town of Irz, the only thing making him want to return to Earth being the concern that his parents are worried about his sudden disappearance. Then comes chapter 10, sweet lord chapter 10.
- Barbie Doll Anatomy: Justified. Since pixies don't wear clothing, they show up nude, in flight, so it's best to simply leave the details of their more... delicate areas unclear. Lily also gets this while she's prancing around nude in her "child" form, so as to not anger the censors. Her "adult" form has clearly visible nipples, if she's not wearing clothes at the time.
- Because You Were Nice to Me: Several examples.
- Kurono falls madly in love with Lily because she's the first anyone who treated him kindly in this new world, and actually cared for his well-being, without asking anything in return.
- Lily falls in love with Kurono because he not only calls her pretty, and means it but clearly treasures her too, despite her half-pixie heritage.
- Atten, the Lamia, gets a crush on Kurono because he doesn't discriminate against her, despite her snake traits.
- Fiona Soleil comes to Kurono's defense in chapter 10 because he gave her some ice candy when he found her collapsed on the side of the road.
- Black-and-Grey Morality: The "monster" races have good and bad mixed among them. The humans are run by a self-righteous "church" that commits every atrocity known to man, and is seeking to assimilate the entire continent where the story takes place via war and conquest, running The Purge on every non-human they run across, and a few of the humans too.
- Blind Obedience: What "White God" wants from its followers. If that involves slavery, drugs, and a healthy Mind Wipe, so be it.
- Bullying a Dragon: What happens when you treat someone who can literally squash you like a bug like crap her whole life because of Maligned Mixed Ancestry, not facing retaliation because she sees no point, and continue to do so when she's telling you to evacuate because she's got a genocidal army hot on her heels, and her beloved is in danger buying time for you? You get squashed like a bug, that's what!
- The Call Knows Where You Live: All Kurono wanted in life is to live peacefully. The White God Church conspires to make that literally impossible, starting with chapter 1, where he was specifically targeted for summoning, and the only warning he had was an ever-growing headache until he collapsed, right in the middle of class. It only gets worse from there.
- Cartwright Curse: Those who confess their love to Kurono tend to have harsh, short lives, or he gets ripped away from them. In chapter 1, he's in the middle of getting confessed to by a girl from his highschool, just before he gets summoned to the dungeon under "White God Church," and several of his love interests in Irz meet gruesome fates.
- Conditioned to Accept Horror: The true goal of all the torture and experiments Kurono is put through in chapters 1 and 2. Repeated gladiatorial fights to the death, unknown drugs, and everything else is purely to break the slave's will so they will obey church orders without question.
- Contrived Coincidence: Kurono is able to escape captivity from the Corrupt Church thanks to a convenient earthquake.
- Corrupt Church: The story starts with the "White God" church summoning Kurono Mao from Earth to this new world, and putting him through things that would make Mendeleev proud. Turns into a Religion of Evil when it's revealed that God Is Evil.
- Crime of Self-Defense: The church considers Kurono a literal devil for escaping their enslavement "laboratory" just before his Final Baptism.
- Dark Is Not Evil: Kurono Mao's name literally translates to "Black Devil King" in-universe, but he's inherently just and noble, even after he gets the capacity to use "black magic" shoved into him.
- Deadly Euphemism: "Perfect liberation" means someone who was so thoroughly Conditioned to Accept Horror that they won't turn on the church the moment the slave collar is broken, as Bishop Judas reveals in chapter 4 when he reveals and shatters Sariel's slave collar that was compelling her to act against Kurono in chapter 2.
- We have no idea what "Final Baptism" means, but considering that it was going to be administered to someone who had to have a slave collar put on him so he wouldn't try to escape, it can't be good.
- Demonization: White God Church and Cross Army, in their entirety, hold themselves completely guiltless of any and all the atrocities they commit by unilaterally labeling the people they kidnap from other worlds, the non-humans they hunt down, and any dissidents as "demons" or "devils" and then treat them as nothing more than mindless feral animals.
- Deity of Human Origin: All gods were first mortals.
- Divine Conflict: A Forever War between the Black Gods and the White God.
- Entitled Bastard: Lilly is a half-pixie, which means she can literally crush full-blooded pixies like bugs. The full-blooded pixies treat her like crap and give her all the "bitch work." They have the gall to be shocked when she retaliates in chapter 10, as she and Kurono are busy fighting White God Church and the pixies still treat her like crap in the process.
- Evil Weapon: Hungry Weapon that born from grudge are everywhere in this world. Kurono have a great affinity with those "cursed weapons". The more you use them and feed them with blood, the more they grow.
- Faceless Mooks: Aside from a handful of the "clergy," including Sariel, the minions of White God Church all wear face obscuring helmets or masks as part of their uniform.
- Fantastic Racism: While most of the racism comes from "White God Church" who are so racist, they think it's forgivable to enslave humans and compel them to fight against the "monster" races, the monster races are a bit racist to the humans, in self-defense. If they meet a human who treats them with decency, they usually mellow pretty quick, although the pixies are very dismissive to half-breeds, as Lily (the girl in the page image) can attest.
- Fate Worse than Death: You do not want to be summoned to this new world. Kurono's treatment in chapters 1 and 2 makes him wish for death, but he gets forcefully resurrected every time...
- God Is Evil: White God is immensely evil and arrogant, and completely genocidal to non-humans and humans who worship any and every other god. It doesn't even have a reason for wanting the continent of Pandora under its control.
- Gorn: The series doesn't shy away from people being torn apart and blown up. But so far in the manga, the point where it starts to genuinely get nasty is when Irz is wiped out as you see the crucified corpses of the townsfolk from Kurono's perspective.
- Half-Human Hybrid: See the pretty girl in the page image? She's half-human, half-pixie. However that works.
- Humans Are the Real Monsters: The "monster" races are shown, for the most part, to simply want to live their lives in peace. The human country is run by a genocidal "church" that commits every atrocity known to man.
- Inhumanly Beautiful Race: Elves, Fairies...
- Innocent Fanservice Girl: Being raised by pixies, Lily normally sees no need to wear clothing, as pixies use magic barriers to protect themselves and see no need to hide their bodies. Kurono has to spell out how that could be "misunderstood."
- Just Following Orders: Sariel, the primary antagonist, knowing full well the genocidal result for conquering the defenders of Irz, still sides with "The White God Church" considering it "her duty." This was forgivable until chapter 4, because she was being controlled by a slave collar, and was magically compelled to obey. After chapter 4, when said collar was destroyed, by the very same bishop who put it on her, and put one on Kurono before putting him through hell, she still sides with the church, despite knowing full well just how atrocious they are.
- Kidnapped by the Call: Deconstructed. Anybody who summons you to a new world to fight their battles for them, without caring for your consent, is not going to care about your well-being or have wholesome intentions.
- Lighter and Softer: As dark as the manga is, the original web-novel was so considerably worse that the author took it down, without notice, forcing all the aggregate translators to do the same. What bits and pieces remain from lead-in trailers highlight all sorts of abuse and torture, and the protagonist Kurono Mao doesn't even arrive in the story until Volume 10.
- Light Is Not Good: The "White God Church" specializes in light magic, and are horrible, horrible people.
- A Nazi by Any Other Name: Not only is "The White God Church" entirely human supremacist, they perform every atrocity known to man, and think themselves "righteous" for it.
- Playing with Syringes: Quite literally. One of the first things Kurono experiences upon reaching this new world is being injected with syringes, contents unknown, and being given a nice taste of hell.
- Pure Is Not Good: "White God" is obsessed with purity. White God only tolerates the existence of 100% pure blooded humans, and then only those that worship it with Blind Obedience, not acknowledging other gods. Lastly, to be considered an apostle, and gain its "Divine Protection" the chosen girl must be a virgin.
- Right for the Wrong Reasons: Kurono splurges in buying Lily a dress, both because she thinks it looks nice, and because Kurono feels uncomfortable sharing a living space with a nude woman. This dress turns out to be stronger than plate-mail and confers all sorts of other protections she'd certainly need when a certain genocidal army decides to march on her home town.
- Satan Is Good: Or at least a shade of grey. The black demon king tries to rescue refugees of Cross Army and does its best to give Kurono his blessings so he can become strong enough to defeat the apostles of White God, although this does involve Kurono going through seven trials.
- Scenery Censor: When Barbie Doll Anatomy won't work, clever use of perspective, camera angle, and the scenery, keeps questionable areas of the anatomy out of view.
- Slavery Is a Special Kind of Evil: The first thing Kurono experiences upon reaching this new world is having a slave "collar" strapped to his head and being forced to not only fight for his life in a gladiatorial arena, but subjected to medical experimentation that makes the atrocities of WWII look like a picnic by comparison.
- This Is Unforgivable!: Kurono's reaction to seeing the atrocities of the self-righteous "Holy church" in Irz? Going totally postal and killing them all
- Ungrateful Townsfolk: A flashback story Kurono learned when getting the cursed sword, "slasher" appraised doubly highlights how Humans Are the Real Monsters. A young mage came to a village's defense, against dangerous beasts, repeatedly coming to the brink of death in the process. When he finally succeeds, with the mayor's own daughter lending him a hand, the villagers, including the mayor, all turn on and decry him, chasing him out of the village, and condemn him for putting the girl in danger, when she's the one that insisted on lending him her strength, despite his objections. Her response? Going full-tilt Yandere and mowing down all the villagers down, starting with her own father.
- The pixies of the forest chased Lilly out, as a baby, for "being defective" ie, being Half-human. Despite this, they constantly send her on errands without a word of thanks, no matter how much she helps them. In chapter 10, she goes "protect these people? Really? HAHAHAHA!"
- Would Be Rude to Say "Genocide": Hunting down and butchering the "monster" races, refusing to accept surrender, to the last child, why that's "proselytizing." Mutilating their corpses and crucifying whatever human-looking parts remain? That's "purifying evil."
- Yandere: Those girls who become Kurono's love interests, but don't fall victim to his Cartwright Curse tend to be a bit "too devoted" to him, and respond with lethal force to any threat, real or imagined. In this story, that's a good thing because the threat is very, very real, and lethal force is the appropriate response.
- You Are Number 6: When Kurono gets the slave collar slapped on his head, The White God Church agents take to calling him "Experiment No. 049." The moment he has any agency, he objects violently.
- You Can't Go Home Again: Twice. Korono gets Kidnapped by the Call to this new world, no known way to get back, and then the town of Irz, where he finds a new home, gets burned to the ground, and that's just the start of the horror.
