233rd hero Alice Claudia and she declares that she'll defeat the demon king emboldened her companions charge forward in the distance the church Bishop is angry at the useless peasants who are hindering the hero's Advance his assistant calms him by saying that the peasants are just cannon fodder once they all die the church Army will swoop in and claim victory however he's worried about whether the hero can defeat the demon king the bishop loudly laughs saying it's fine as she loses as they have a secret weapon meanwhile Alice notices that her companions are overwhelmed by the
monsters she moves to save them when the bishop summons the weapon he declares that the church has been preparing for a hundred years [Music] has a large flying whale appears he calls it the most fearsome weapon on the continent the fighting stops as everyone stares at it the bishop commands the whale to attack shocking Alice as this will wipe out the entire Vanguard Squad horrified she realizes she can't make it in time to save them Merlin clicks his tongue calling the whale ugly while humans and his minions brace themselves for the attack with a mighty
Boom the whale's Laser cannon hits them and the bishop boldly declares that he sentences the demons to Hell When the Smoke Clears Alice sees the backs of a man and a woman both humans and monsters are alive which confuses them Merlin says that of course they're not dead as only he can decide whether they live or die he challenges the men from church to come at him and the bishop who is in utter disbelief gets angry his assistant asks him if they should Retreat as the demon king is much stronger than they anticipated but the
bishop declares that there's nothing to fear as the church's whale is on their side convinced that The Demon Kane will not be able to withstand the whale's body slam he can transit to attack Merlin comments on how weak the whale is but he decides to humor them as the whale's Jaws head toward him Merlin says that he'll deal with it with the barest unsheathing of his sword in the next moment the whale is already sliced in half by his blade Lilith fangirls Alice is wide-eyed and while the whales have body falls his minions the bishop
and the rest of the humans drop their mouths in shock when the two pieces of the whale finally land heavily on the ground Merlin sheets his sword which his sister finds utterly cool while Alice is taken aback by his strength the men from church become horrified Merlin tells them that it's their turn next has the demon king of the first palace he declares that he'll grant them glorious deaths the bishop pleads for Alice to save them and as the hero she must stop him gripping her sword tightly she challenges him to a duel when she's
about to attack his power blasts from his body pushing her back he unsheets his sword once again but he doesn't attack her his Blade's powerful strike is aimed at the bishop and the church's Army which obliterates them before the attack even lands Alice gets thrown even farther back by the force while and a resounding boom fills the whole area The Bishop's cap floats uselessly in the air and not even a single soldier survived Merlin glances at the unconscious hero the final battle of demon Kane Merlin has just ended but it also marks the beginning of
the story between the jobless demon king and the hero Merlin was once a human summoned into another world by the altar though he was born powerful he is also cursed his lifespan shortens as he suffers hard touches throughout every moment of his life fortunately his demon sword called adernum augments its user's life each time it's used to slay powerful enemies with it he manages to temporarily alleviate the effects of his curse the stronger the enemy that he slays with his sword the greater the effects the sword's ability has on him Merlin wishes to one day
meet with the strongest person in the world and defeat him as he believes it will lift his curse he tells himself that it's finally over that he's no longer needed in the demon Palace planning to leave soon he gets approached by Lilith he tells her not to be upset before instructing her to take care of herself once he's gone she tries to protest and tears pour down her face as she begs him not to leave her behind fondly he reminds her that she's already a big girl he clutches his chest asking her if she'd rather
that he die as the curse will eventually kill him she hugs him saying she doesn't want that to happen too she proposes that if his curse relapses he can use her life to extend his shocked Merlin flicks her forehead and calls her a foolish girl he tells her that he can never do that to her she tells him she doesn't want him to leave and she wouldn't even care if he turns into a useless need which makes him wince chuckling Merlin tells her that he loves her but he must go once he finally lifts his
curse he swears to return and never leave her again he tells her that not even death will tear them apart Lilith blushes utterly delighted she feels like he cheated by saying all that is she can no longer continue to be willful before he goes she has a piece of advice for him making him curious she warns him that there are a lot of huskies out there so he needs to watch out or else she'll kill them all she'll pull their hair out skin them alive roast them over lava and turn them into meat jerky before
eating them all up shocked Merlin only realizes now that his sister is a yandere quickly he bids her goodbye and upon passing by the unconscious hero he notices that she's having a good sleep he hoists her over his shoulder which shocks Lilith menacingly she asks Merlin if the hussies have already appeared and he quickly explains that the woman is going to be his slave as he doesn't know much of the world outside he needs a gopher with him during his journey he tells her that though the wound is too weak for a hero her stamina
and willpower are somewhat decent so she'll be useful to keep around Lilith pouts saying he should just kill her as she's a hero but he tells her it's fine once the sun sets he'll no longer be a demon king he waves her farewell as he assures her that he would never fall for a hero Lilith is sad to see him leave but she tries to shake away her Sadness by recalling his words she blushes and deems what he said to her as a confession she can't wait to meet him again becoming determined she plans to
complete her Bridal training before he returns she'll then capture his heart as a virtuous wife meanwhile Merlin and Alice are about to start their journey together while Merlin carries Alice on his back her unconscious mind wonders if she lost ever since she left the mountains a lot has happened to her she fell for the words of flattery told to her by the people from the church she thought she could defeat the demon king but seeing how he easily killed the church's Ultimate Weapon she realizes they were not even in the same league her master had
told her that she was still lacking in cultivation and that she'll face many difficulties against strong opponents Alice only now realizes that her master's words were true meanwhile Merlin spots the wreckage of some boats by the shore depositing the hero against a coconut tree he tells himself that he needs to think of another way to get a boat after he leaves the sleeping Alice attracts the attention of a beast with long and sharp teeth it's drool drips on her and she wakes up only to find a large demon wolf before her Alice is scared and
as the wolf is about to pounce on her she realizes she's done for as she can't escape with superhuman speed Merlin intercepts the wolf's attack and instructs the Beast to stand down the demon wolf growls and Merlin tells it that it can't eat her as she is his while the wolf calms down the hero realizes with a blush that she's been saved by the man again making her heart skip the wolf becomes putty in Merlin's hands and Alice can't help but think that the radiant smile on his face is not of a villains shaking her
head she adamantly reminds herself that he's the Demon King saving her means that he has some ulterior motives after sending the wolf on its way Merlin turns to her and asks her if her name is indeed Alice immediately she goes into defense summoning her sword and asking him what he wants in her vision he looks extra Sinister when he asks her what she thinks he'd want from her as Alice thinks that he has perverted intentions toward her while Merlin introduces himself she charges toward him with her sword which she easily stops Alice is shocked while
Merlin merely hums he grasps her chin calling her a pretty little lady before declaring that from then on her body belongs to him she whimpersed before slapping his hand away she demands that he not humiliate her as she would never bowed to an evil being like him he stares at her before shrugging saying that she misunderstood something as it's neither request nor negotiation he declares that he is her kidnapper before coming toward her and trapping her against a tree with a smile he tells her that he's a gentle person which makes Alice blush she concludes
that he wants her to submit to him but still she wants to make it clear what he wants her to do after thinking for a bit he smiles at her evilly before saying that he'll have her body do something very unreasonable and inhumane which horrifies her Alice knows that some demons can impregnate human females but she doesn't want that to happen to her as she hasn't even gone on her first date yet Merlin grabs her hand and tries to drag her with him but when she resists he clicks his tongue in annoyance and carries her
Bridal style he tells her not to blame him if he gets rough and a moment later he tosses her on a boat with a Sinister smile he announces that they should start while Alice yells that he should stay back with her sword in hand Alice glares at Merlin greeting her teeth she threatens to kill herself if he's going to force himself on her noticing the oars by her feet Merlin Stomps on one end of an ore which then hits her face making her drop her sword Alice whimpers in pain while clutching her face Merlin scoffs
wondering how a dumb chick like her became a hero with tears in her eyes she tells him there's no need for him to get violent that he wants to get it on with her scoffing once again he tells her that her washboard body is unlikely to get him into any kind of mood flustered she takes offense at what he said saying her body is normal for a girl her age but he calls out her lie saying he knows there's a metal plate in front of her chest as it was chafing his back when he was
carrying her embarrassed she tries to tell him that it was her mithril armor which makes Merlin laugh that she uses armor as breast pads annoyed she asks in why he kidnapped her then and he points toward the oars beside her he declares they're sailing across the Strait of orkney to enter the territory of Great Britain stunning Alice she tells him that would be impossible as even the church's warships need hundreds of oarsmen assisted with wind magic and a hold age across the ocean not to mention the countless sea creatures lurking within it that even saint-ranked
individuals have trouble fighting against she continues to say that even if they take turns rowing it'll be impossible for them to make it out alive they'll just end up a shark bait Merlin Chuckles saying she misunderstood again as he told her he plans to have her body do some unreasonable things so the one who'll be rowing the boat will only be her as for him he'll just stand and enjoy the cool Sea Breeze baffled Alice stares at him uncomprehendingly before shouting in disbelief three days later the sea has become rough due to the storm while
Alice Rose she comments that it's weird that they're yet to see any sea creatures planning to attack them Merlin replies that it's because there's a big monster falling right behind them that keeps all the small fries away he tells her to sit tight since he can't swim if she falls off the boat she'll be on her own Alice tells him that she once heard him destroy a sea monster with his bare hands which Merlin confirms to be true [Music] suddenly a sea monster emerges from the deaths Merlin declares that this monster is much bigger than
the one he killed the monster capsizes their boat tossing them in the air as they fall Merlin kicks the edge of the boat to make it land upright in the water and the two of them land on it just in time the sea monster Roars ferociously and judging by its size Alice realizes that it could be the overlord of orkney who sank Britain's royal Navy and killed two saint-ranked magicians on board wondering if he can fight the monster she asks him what they should do but Merlin doesn't reply Sky rumbled while the sea creature looks
at them meanly Alice becomes silent before quickly spiraling into despair she looks up when she hears snickering it's Merlin who's pointing at the monster and calling it ugly laughing boisterously now he loudly says that though the monster's neck is so thick its head is small Alice is frustrated that he's still in the mood to make fun of the Lord of orkney angry the sea monster raises its tail and slams it into the surface of the water creating even bigger waves Alice asks him how they're going to fight a monster whose power can rival that of
nature the monster continues to thrash in the water the resulting waves tossing their boat about Merlin clicks his tongue and draws his sword facing the Behemoth that is about to plow into them the sea monster Roars launching itself toward them and Merlin responds by unsheathing his sword after executing a wide slash he smirks while Alice watches wide-eyed the sea monster freezes and somehow the turbulent Waters start to calm down a bit with a flick of his sword Merlin returns eternum to its Scabbard he turns his back on the monster scoffing at how easy it is
Alice is still not moving due to shock so Merlin pinches her cheek he tells her to start rowing but she protests pointing at the sea creature behind him however a second later the behemoth's body Clacks before collapsing to pieces and falling into the ocean Merlin merely asks her what she was saying he tells her that if she doesn't start rowing man-eating sharks will turn her into shark bait Alice gets to work while she stares at Merlin pensively she Muses that even on the ocean he's unbelievably strong if she allows him to arrive in a country
of humans there could be dire consequences
