Clevatess Episode 1 Summary

Clevatess, the most feared demon king in existence, has one mission—wipe out every last human. Why? Because he really doesn’t like people. But fate has other plans. Just when he’s about to go full extinction mode, a random human baby pulls the old “puppy dog eyes” trick and somehow melts his stone-cold heart. One adoption later, the terrifying king of monsters is now playing the role of undercover single dad, pretending to be just another average nobody in the human world.

Meanwhile, a team of elite heroes charges into a cursed forest with a noble goal: reclaim their homeland. These aren’t your average adventurers—they’re armed with Regalia, legendary weapons juiced up to give them powers that’d make even a demon sweat. The squad is pumped and ready to face down any threat… until a dark beast casually yeets their wagon driver into low-orbit before they can even draw their weapons.

Their leader, Stefan, quickly calls for formation, rallying the team into a heroic charge. One guy, the cutlass wielder, goes full blender-mode, slicing monsters into fine sushi with his whirlwind technique. Meanwhile, Stefan beheads a giant snake like he’s done this before—twice before lunch. Problem is, the snake didn’t get the memo—it tries biting Stefan even without its head. Luckily, Alicia shows up just in time and stabs it through the eye, finally shutting it down for good.

With the small fry handled, the team heads deeper into the cave in search of the real boss: the Beast Lord of the South. They reach the core of the cave and encounter the legend himself—Clevatess of the Moonlight. And you know it’s serious when the villain has his own ominous aura intro.

Stefan, ever the optimist, believes in the power of friendship. But friendship’s got nothing on Clevatess, who proceeds to redecorate the cave walls with Stefan’s blood. Brutal. The party’s tank steps up to avenge him with a flying leap—and promptly gets beheaded mid-air, proving that jumping at angry demigods is a bold but terrible strategy.

Panic sets in as Clevatess begins picking them off one by one. His movements seem instant, almost supernatural. That’s when Alicia notices something terrifying—the attacks are coming from their shadows. She yells for everyone to jump and create distance. Her quick thinking lets her barely dodge a fatal strike, but most of the others aren’t so lucky.

One hero tries to summon an earth golem using his spear, but that’s a rookie mistake—the entire cave floor is under Clevatess’s control. Before the poor guy can say “Regalia,” he’s Swiss cheese, courtesy of some nasty tail spikes.

Another hero tries a frontal charge, but Clevatess just watches with casual curiosity, wondering how something so weak made it this far into his lair. Then he finishes the job, cleaning up the survivors like he’s swatting flies.

Only Alicia remains. She’s darting through the air with her sword, desperately looking for an opening. She finally gets close enough to land a direct hit to Clevatess’s face. It’s a solid blow… that leaves nothing but a tiny scratch.

As Clevatess reflects on the sheer stupidity of humanity—attacking him unprovoked after a thousand years of peaceful isolation—he decides it’s time to send a stronger message. First step: deal with Alicia. He slashes off her limbs and sends her plummeting to what looks like certain death.

A little while later, Clevatess crash-lands in the human kingdom—fully in vengeance mode. He had no plans to invade human lands as long as they minded their own business. But nope—they just had to start conquering, poking the big, scary bear that is Clevatess. Based on what the so-called “heroes” blurted out before they got vaporized, they were sent by the King of Hayen. So now, Clevatess is paying him a very personal visit.

Naturally, the kingdom’s archers spot the incoming doom and open fire. And just as naturally, their arrows bounce off Clevatess like foam darts. But hey, points for enthusiasm. Despite the hopeless odds, the soldiers keep attacking like their training manuals never covered the words “fall back.”

Clevatess had originally planned to march right past them and head straight for the king—no distractions. But since they insisted on poking the god-beast with sticks, he politely slaughters them all as he strolls toward the castle.

Inside the fortress, the guards scramble to prepare the heavy artillery—catapults, ballistas, the works. Spoiler: they’re as effective as throwing paperweights at a tank. Clevatess tears through the walls like tissue paper, heading straight for the throne room.

Meanwhile, a panicked guard rushes in to warn the King of Hayen. But the king, already listening to the explosive demolition symphony outside, is like, “Yeah, I figured.” He knows the heroes failed—their Regalia weren’t strong enough. And he knows Clevatess is here for him.

Fleeing? Not an option. There’s no hiding from a creature that can sniff out your fear like blood in the water. But the king, resigned to his fate, decides to do one last thing—seal off the sacred Forge of Hayen so its flames may never fall into enemy hands.

Outside, Clevatess pauses to reflect—why are these current humans so weak compared to the ones who attacked his lair? Was it some elite training program? Or… was it the weapons?

Then it hits him: even Alicia‘s sword—while barely a scratch—did manage to mark one of his horns. Which shouldn’t be possible. If humans are insects, then some of them are walking around with very pointy stingers. And now he’s curious.

Back inside the castle, the king reaches the forge chamber, just in time for the ground to quake. Not a good sign. He quickly seals the room—but moments later, Clevatess peels the castle roof off like a sardine can.

The two lock eyes. The King of Hayen tries to play it cool, throwing some royal shade: “You don’t have the right to address me like this.”

But Clevatess isn’t in the mood. “Watch your tone, little man,” he growls. “I could end humanity in a blink. Not just this kingdom—all of them.” And he means it.

Still, rather than killing him instantly, Clevatess gives the king one last chance: “Why did you send your warriors into my land?”

The king scoffs and basically spits in his face: “You’re just a beast. You’d never understand human ambition.”

That’s all Clevatess needs to hear. With one clean slice, the king’s head hits the floor. And now the decision is made—humanity has earned a total reset. Time to wipe the slate clean.

But as he walks through the ruins of the kingdom, something unexpected happens. He hears a baby crying. Its mother lies crushed beneath rubble. Clevatess—cold, unfeeling, busy being genocidal—decides to ignore it and keep walking.

Then the mother speaks. With her last breath, she begs Clevatess to save her child.

He stops. Not out of compassion—but confusion. Did she just ask that of the guy who just destroyed her kingdom? He reminds her plainly: “I’m the one who brought ruin to your people. I’ve already decided to end your kind. Why would I save your child?”

The mother, barely alive, replies calmly. She knows. But she pleads anyway—saying the baby hasn’t done anything wrong. The sins of the adults shouldn’t condemn the innocent.

Clevatess doesn’t exactly buy into the “innocent baby” argument. To him, a human is a human—small, loud, and generally annoying. But, in a rare moment of curiosity, he humors the dying mother. He asks her to prove the baby’s worth. Of course, she knows there’s no convincing a being like Clevatess, especially with her clock ticking. Instead, she makes a promise: if he agrees to spare the baby, one day he’ll see the child’s value for himself.

She dies shortly after making that heartfelt plea, and Clevatess walks away, stone-faced and seemingly unmoved… until he circles back and picks up the baby. So clearly, something about her words reached even his cold, monstrous heart. He’s still not convinced this is a good idea—babies are messy, noisy, and extremely mortal. But hey, what’s one short human life to someone with a lifespan measured in millennia? He’ll look after it, at least out of curiosity.

Now, let’s talk about the world of Ethia, where this mess is unfolding. There are five humanoid races:

  1. The Dun – populous and skilled architects.
  2. The Orgites – masters of hunting and medicine.
  3. The Sladens – aquatic folks who basically live in the water and make excellent fishermen.
  4. The Benty – individually strong, collectively hopeless. Think gym bros with no group project skills.
  5. And lastly, the now-destroyed Kingdom of Hayen, the oldest race, known for crafting powerful weapons—the famed Blades of Hayen.

Ethia is surrounded by darkness on all sides. Beyond its borders lies the land of the dark beasts—monstrous beings ruled by the four Dark Beast Lords, one of whom is none other than Clevatess himself. So, it’s safe to say no human has ever taken a casual vacation outside Ethia.

Back in Clevatess’s cave, he brings the baby home. First order of business: make sure none of the nearby monsters eat it. So he flexes a bit, scaring off the wildlife, then curls up next to the child for a nap. But the peace doesn’t last long—there’s a new issue.

The baby is covered in poop. And Clevatess? He’s many things—killer of kings, destroyer of cities—but he did not sign up for diaper duty. So, without a second thought, he picks up the stinky bundle and drops it into a pit of spiders.

Naturally, the baby starts screaming bloody murder. Honestly, who wouldn’t? But Clevatess reassures the child—sort of. The spiders in that pit only eat poop, not babies. So technically, this was his version of a bath. Not comforting, but effective. Even after pulling him back up, the baby continues wailing, and Clevatess starts losing patience.

Still, he’s made his choice. And a Dark Beast Lord doesn’t back out of decisions—especially not mid-diaper crisis. He realizes he’s going to need help—human help—to care for the child properly.

So what does he do? He goes corpse-shopping. He walks over to the pile of fallen heroes to see if any of them might still be useful.

A few moments later, Alicia opens her eyes and stares up at the cave ceiling, confused. She clearly remembers dying… so where is she? When she sees Clevatess, it all comes flooding back. She instinctively reaches for her sword—but Clevatess calmly tells her not to bother. He tossed all their weapons (and her friends) into the ravine already.

Still, she looked vaguely useful, so he decided to bring her back. She’s technically undead now—a walking corpse powered by his dark energy. No big deal. But before she can process that existential horror, Clevatess gives her a very weird command: “Give me some milk.”

Alicia freezes. Did she hear that right?

She did.

He’s dead serious.

And it’s not a request.

He uses his powers to force her to comply, even holding the baby up to try and make something happen. Several awkward minutes of silence (and baby suckling) later, Clevatess finally accepts the reality: this isn’t working.

Alicia, both mortified and annoyed, explains the obvious—she’s never had a child. She can’t produce milk. And she really doesn’t get why someone like Clevatess, king of the murder monsters, is suddenly playing single dad.

Clevatess has no intention of explaining himself. He just knows one thing—if Alicia can’t give milk, she’d better find another way to be useful.

The baby won’t die as long as Clevatess keeps pumping it with his dark energy—but that doesn’t stop it from being perpetually hungry. And unfortunately, feeding a baby magical demon aura isn’t a long-term solution. So, Clevatess turns to the most reluctant babysitter in history: Alicia. He demands alternatives.

Bound by his command, Alicia sighs and explains that what they really need is a nursing mother. You know, an actual human who produces actual milk. But that means heading to a human town… which poses a small problem: Clevatess, in his monstrous beast form, would send the population into full-blown panic mode.

So, time for Plan B: disguise.

Using what little reference he has, Clevatess shapeshifts into the image of the baby’s mother—because why not—and announces his new human alias: Krenn. As for the baby? “Her name will be Luna,” he declares. Then he orders Alicia to lead them to the nearest village.

But first—pit stop. Alicia wants to clean Luna‘s blanket, probably because even legendary forging crests shouldn’t smell like spider poop. While washing it, she notices something… odd. The blanket is embroidered with the Heiden Royal Crest.

Meanwhile, back in the charred ruins of Hayen, word of the kingdom’s destruction has spread. A scout arrives to confirm the rumors and is absolutely stunned. One dark beast did this? He had warned the higher-ups that provoking a Dark Beast Lord was suicidal, but nooo—humans just love poking things bigger than them. To make matters worse, the attack happened on the very same day the crown princess was supposed to escape the kingdom—with her newborn son.

Back at the riverbank, Alicia confronts Krenn.

“Did you know Luna is royalty?”

Krenn blinks. “What?”

She points out the crest on the baby’s blanket. Only royal family members are allowed to use that cloth. Now that Krenn thinks about it, the mother he found Luna with was buried under castle rubble. It adds up.

But Krenn shrugs. Royal or not, it doesn’t change his plans.

Wait—castle rubble?

Alicia freezes. “What do you mean by that?”

So Krenn, ever the blunt monster-turned-mother, casually replies, “Oh. I destroyed Hayen and killed the king. Last night.”

Cue internal screaming from Alicia, who now realizes she’s technically working for the guy who annihilated her homeland. But Krenn defends himself—he didn’t start the war. The humans sent warriors into his domain first.

Still, Alicia insists this is a big deal. If Luna is the last surviving royal, and Krenn is walking around with him, then every major power in the continent is going to come hunting.

“Why?” Krenn asks.

Alicia, realizing she’s about to say too much, accidentally blurts out the truth: only members of the Hayen royal bloodline can wield the sacred forging techniques used to create the Blades of Hayen.

Oops.

That bit of info instantly flips a switch in Krenn’s mind. He hadn’t really decided what to do with Luna before, but now… if this kid is truly that valuable, why not make him the next king of the humans? With Krenn pulling the strings behind the scenes, he could control all of humanity—and crush them again if they ever stepped out of line.

But for now? Baby’s still hungry.

So, Krenn orders Alicia to get moving—they need milk, not a political coup. Alicia, still reeling, doesn’t understand why Krenn is so attached to Luna, but one thing is certain: if anything happens to the child, Krenn will probably annihilate the entire continent out of spite.

Which means, like it or not, she has to protect him.

And with that, Episode 1 comes to a close.
