A/N: And a little heads-up here. The rest of the story might have M-rated material (the warnings will explain what kind). So, because of that, there's bound to be a warning that should refrain younger people from reading stuff like that unless they're 18 or older. Just wanted to be sensitive about this before we go on any further. Anyway, let's continue, shall we?

The Owl House: The Curse of the Were-Oni

Chapter 2: The 1st Night

Later at night, outside of the Owl House, as Alador brought Lilith up to speed in the severity of Amity's situation moments earlier and asked her for help in holding Amity down when she transforms in the event that the aforementioned curse in King's Book of Demons turns out to be real, Luz was already tying Amity up, sexy bondage style sans the gag while Willow, Gus, and Hunter helped make sure the knots were tightened.

"I can understand tying you up to hold you back in case you do turn, but why did you want me to do it like this?", Luz asked, finishing the knot of the ropes.

"I just feel a bit horny, I guess. Might be a witch puberty thing.", Amity blushed.

"Yeah, that'll do it. I think...", Camila admitted, giving an uncertain blush.

"Well, that could happen.", Willow responded.

"And I wanted to do a bit of a step-up from tying someone to a chair. I mean, we are outside.", Eda responded.

"And why are we outside again?", Emira asked.

"Because, Blight sister, if the curse actually is true and she turns, I don't want the house damaged.", Eda responded.

Hooty, however, was not convinced as he was whimpering while the Porta-place for Hooty was shaking.

"What's the matter, Hootsifer?", Lilith asked.

"Isn't it obvi, Lulu? I'm deathly terrified of Amity.", Hooty replied, shuddering in fear,

"Hmm. Well, that porta place ain't gonna protect you.", Eda commented.

Hooty only stopped shielding himself in disbelief.

"Fortunately for you, Hootsifer, that's where I come in.", assured Lilith as she turned her arm into a harpy claw, giving him hope as he gasped with joy.

"And until then, you can get this under control, Sweet Potato. ARE YOU READY TO OVERCOME THIS THING?", Luz asked.

"I think so.", Amity replied.

"I said... ARE YOU READY TO OVERCOME THIS THING?!", Luz shouted.

"Yeah. I heard you, Luz. I said I think so.", Amity repeated.

"Oh. Sorry. I was just tryin' to get you to shout.", Luz explained.

"Oh. Okay. LIKE THIS?!", Amity shouted, making Luz yelp in surprise a bit.

"Never mind. We'll work on that later. If there IS a later...", Luz sighed.

"Now, I want you to think about draining a glyph while it's being activated. How would that feel?", King asked.

"Singey and painful.", Amity replied.

"Ah, there we go, you're doin' great!", King grinned.

"Well... so far, so good.", Alador smiled hesitantly.

"Cool. So, can I drain one of those glyphs now?", Amity asked.

"No way, José. You ain't drainin' nothin'.", Eda refused.

"But I'm hungry... so HUNGRY!", Amity snarled.

She started to growl fiercely as her eyes started to black out completely.

"Amity!", Edric and Emira shouted in unison.

"And there it is.", Alador said.

"Mmmurrrraaaah!", Amity shouted, her teeth turning into fangs.

"Wha? Why do I feel so weird! Like-Like I'm-Aaaaggghhh!", Amity shouted in pain, the transformation finally started.

"Oh, no, that demon is already taking her over!", Eda spoke worriedly.

Amity gasped as she saw her hands inflate and swell up while her skin color changed to a Lavender color.

"What-what's happening… t-to… Meeee?!", Amity groaned.

"Amity, please, try to stay calm. Remember who you really are.", Luz urged.

Amity's butt suddenly started to grow bigger, making her pants tighter.

"Grrr...! I-I'm trying..., Luz...!", Amity groaned.

Alas, her rear end only kept growing until her pants ripped off completely as did her underwear, making Amity and Luz blush completely red. As if that wasn't enough, Amity started convulsing in pain again, prompting Luz to make a frightened noise and back away quickly.

"Everyone, we need a silver arrow!", Hooty urged.

Then, the full moon outside was shown and shone from behind the clouds. Helpless, Amity grunted as her feet grow, causing her shoes and socks to burst. Right after that, her legs swelled up and enlarged; not to mention that her arms swelled up, too.

"Agggh! No, no no!", Amity yelled in pain and worry.

Her body grew larger up to 12 feet in height and 6,000 pounds in weight while her pointy ears grew longer and became horn-like in appearance.

"Stop...! I-No...! I'm me! I-AAAAAAAAGGGHH…", Amity groaned, her one last grunt turning into a distorted moan as her belly and breasts expanded outward and swelled up, finally ripping her clothes apart completely and becoming exposed to the air, its briskness causing her nipples to harden.

It was no longer Amity. Just a large, gigantic demon that now stands in her place.

"I'M... AN ONI!", the Were-Oni shouted before howling.

"AMITY!", Luz and Alador shouted.

"¡Ay, mi titán, ay, mi titán, ay, mi titán, ay, mi titán, ay, mi titán, ay, mi titán, ay, mi titán, ay, mi titán!", Camila shouted repeatedly and quickly in fear.

"You! Titan... Why have you disturbed our sleep, awakened us from our ancient slumber?", the Were-Oni glared toward King.

"What? I don't even know what you're talking about!", King reacted.

"It doesn't matter! You will die! Like the others before you! We will take you one by one! ALL OF YOU!", the Were-Oni threatened before laughing demonically.

Hearing the demon that used to be Amity laugh was more than what Luz could bear as her heart broke.

"No...!", Luz teared up.

As scared as everyone is, the only one who was more so was Hooty, who sprayed out tears like a waterfall.

"SCREAMOOOO!", Hooty sobbed.

Eda and Lilith, having had quite enough of the terror, growled angrily and went harpy mode on the demon, grabbing her arms.

"All right, you! I don't know who you think you are, but nobody, I repeat, NOBODY makes Hooty cry and gets away with it! Only I can do that.", Harpy Eda glared.

"I'm not entirely sure how to feel about this, Edalyn. And as for you...! You better release Ms. Blight right this instant or...!", Harpy Lilith began.

"Ms. Blight's with the maggots now!", the Were-Oni discouraged before swiftly tossing both harpy ladies around and smacked them against each other as they crashed to the ground right into a bush with both Harpies popping out.

"Hey! You don't smack us around when we're talking to you!", Harpy Eda glared.

"Let us handle this one, guys.", Willow urged as she drew a spell circle and used it to bind the were-oni via vines wrapped around her corpulent, demonic body.

"We know you're still in there, Amity. Fight it.", Gus urged, starting to draw a spell circle.

But the were-oni only smirked before she started to suck up Willow's vines into her mouth like a vacuum, much to Willow's shock. But she didn't stop there. She also managed to suck in Gus' spell circle just right after it was completed. It was only after she finished sucking up all the vines that Willow and Gus turned pale and collapsed in exhaustion.

"Willow! Gus!", Luz shouted.

"I feel... so weak.", Willow groaned.

"Did we learn nothing from the greater basilisk incident? Nothing...?", Gus asked dramatically before the were-oni slurped her forked tongue and smacked her lips.

"That was exquisite...! I need more...!", the were-oni smirked before then picking up a scent of magic nearby.

"And I know where to get it...", the were-oni stated.

Then, she quickly bolted out into the forest.

"Amity!", Luz called.

But there was another problem to consider: Willow and Gus' current condition.

"But what about you guys? Are you gonna be okay?", Luz asked.

They tried to get back up, but it was no use. This prompted Hunter to pick them up.

"You leave them to me.", Hunter urged.

"You guys just worry about keeping Amity under control.", Camila urged.

"That's right, Luz. Go get her.", Alador agreed as he and Camila held onto Hunter before he left in a flash, taking Alador, Camila, and the weakened Willow and Gus with him.

Luz could only nod in response before she got out Stringbean and flew off toward the direction the Were-Oni charged out, but in the air.

Down below, Eda and Lilith turned to one another.

"Well, should we?", Lilith asked.

"At least for now.", Eda responded.

"I'm coming with you. You're gonna need someone who's got the know-how on were-oni.", King urged.

"Looks like you're right on this one. Luz could use all the help she can get, anyway.", Eda responded.

"And me, too?", Hooty asked.

"What? But aren't you scared of Amity?", King asked.

"Deathly afraid! But I'm even more worried about losing Lulu.", Hooty replied.

"Oh, Hootsifer. Of course you can come along.", Lilith responded.

Then, the two harpies flew off with King and Hooty in tow after Luz from a distance.

Down below in Bonesborough, the Were-Oni stomped around looking for some magic to drain. And sure enough, who should she find, but a few gremlin con artists. This earned a nasty smirk from the beast.

"Okay, look. How's this for a perfect con? We set up a big crime scene...", the first gremlin suggested.

"Uh-huh...", the 2nd spoke.

"And while everyone is all gathered around, distracted...", the 1st continued.

"Go on...", the 3rd responded.

"And take all their wallets!", the 1st finished.

The other 2 gremlins spoke over each other about how great the 1st gremlin's idea was. Suddenly, they heard a loud stomping noise from a distance, which stopped their chatter.

"Wait, guys. Did you hear somethin'?", the 1st gremlin asked.

Then, he and his buddies turned around, trying to look for the source of the stomping, but saw nothing. Granted, it was very dark out, but still.

"Eh, it was probably just someone's abomination or somethin'.", the 2nd gremlin guessed.

"Could be.", the 3rd concurred, starting to get nervous with a chuckle.

But then, the stomping returned, this time accompanied by a loud growling sound.

"That don't sound like no abomination I ever heard!", the 1st gremlin shouted before he and his 2 partners in crime ran in fear and eventually went inside a cave where Tiny Nose, Matt, and Tibbles used to work together.

"Whew...! Made it.", the 1st gremlin sighed in relief.

But the truth was, they hadn't made it at all. The 3 gremlins turned and saw the Were-Oni right behind them and screamed in shock and horror.

"Hey, there, boys. Going somewhere?", the Were-Oni asked before inhaling with her mouth, sucking up all the magic they were trying to hide, that is if they even were trying to begin with, and then swallowing their magic essence whole, leaving the 3 gremlins pale and exhausted before they collapsed.

"Mmmm... Tasty. But I wonder if I can find something more... filling...!", the Were-Oni smirked before stomping away.

"Am I just tired...? Or do you guys have no idea what's going on, either?", the 3rd gremlin asked, exhausted.

"Both...", the first 2 gremlins responded before they let their heads fall onto the ground.

Meanwhile, a witch was wearing a Coven Scout uniform, sans mask.

"Surely, this uniform will sooth my frozen skin with warmth.", the witch spoke, admiring the cape for a moment before proceeding onward.

Little did he know that the Were-Oni was just around the corner, growling as she peered through the bushes.

"Hello...?", the witch puzzled.

Suddenly, the Were-Oni roared demonically as she charged toward the witch, her rotund body jiggling with every step.

"Good heavens! A Diabolope Juggernaut!", the witch shouted in surprise before screaming.

The Were-Oni then clutched onto him.

"Meal time!", the Were-Oni smirked before sucking up his magic essence with her mouth, turning him pale and exhausted as well.

"Not filling enough. But it'll do for an appetizer.", the Were-Oni spoke before stomping away as the weak witch groaned.

Meanwhile, Luz, King, Eda, Hooty, and Lilith looked down to see the brewing chaos as some people were panicking and fleeing away.

"Looks like the Were-Oni's been busy.", Lilith said.

"It's madness down there! Madness!", Hooty added.

"We have to stop that thing and save Amity!', Luz urged.

"And whatever we do, we better do it fast! If the demonic spirit that's possessing Amity isn't exorcised in less than 10 minutes, she'll be stuck with that demonic spirit in her body forever!", King shouted, holding out his book and pointing to the entry in question.

"Well, it's not going to come to that! I already had one person live with that kind of curse for years...!", Lilith began.

"Who knew it'd grow on me after so long, am I right?", Eda asked.

"I am not about to let one more person be forced to live with a curse again!", Lilith finished.

"King, what's that way you mentioned?", Luz asked.

"It may seem kinda vague, but it says here that in order to exorcise the demonic spirit, one needs to invoke to the victim a remembrance of love, or a deep, emotional connection.", King responded.

"Are you serious?", Eda asked.

"Hey, I did say it was vague, okay?", King asked.

"Well, at least there is a way. I just hope it's not too late.", Luz said before she, Lilith, Eda, and King went faster in the air.

Meanwhile, the Were-Oni leapt toward a rooftop and gazed down, seeing former Coven Heads Terra Snapdragon, Adrian, and Vitimir together.

"All I'm saying is this is the perfect opportunity to take the Boiling Isles and rule it.", Terra smirked.

"Perhaps it is...", the Were-Oni replied.

This reply caught the trio by surprise and who should they look up to see, but the Were-Oni, who crashed down in front of them with a stomp.

"But it won't be you who rules the Boiling Isles.", the Were-Oni smirked before the three prepared to fight, arming spell circles at the ready.

"All you're doing is bringing me more morsels of magic to devour.", the Were-Oni discouraged before then draining their magic into her body as well, attracting Luz, King, Eda, Lilith, and Hooty's attention.

"Man! That's good eatin'!", the Were-Oni laughed.

"There she is!", Luz shouted before zooming down just as the Were-Oni then left them pale and exhausted as well before they collapsed, allowing the Were-Oni to turn to see the 5 interlopers.

"Figured we'd find you in the middle of your gluttonous magic feast, you demon creep.", Eda glared.

"Don't get much past you, Owl Lady.", the Were-Oni smirked.

"Amity, I know you're still in there. You have to fight it! Please!", Luz pleaded.

"I'm afraid Amity's not home right now.", the Were-Oni discouraged.

"If you are in there like I know you are, then listen. I've known you long enough to know that you're not the kind of girl who'd give up easily. Not like me back when we came back to the Boiling Isles to save Eda and King 4 years ago. Before Mama helped through a rough patch, even before Kikimora and Boscha showed up together, I was going to tell you that I was going to stay in the Human Realm permanently. After what I did to help Belos meet the Collector for the Day of Unity, I thought that everyone would hate me if they found out, that I'd never fit in anywhere ever again! That is, until Mama helped me realized what I really wanted and even helped Stringbean hatch...! That goes to show just how much stronger you are than me, Amity, so prove that to me again!", Luz urged.

But the Were-Oni only laughed.

"Witch, please. Did you really think that this little sob story would work on me?", the Were-Oni laughed before then using Terra's vines to lurch them toward Luz, who screamed in fear before Eda slashed at said vines before they could reach Luz.

"Wait... Those're Terra's vines. How did she...?", Eda began.

"Uh-oh. Apparently, Were-Oni can use the magic they drain away from various sources.", King stated.

"And you didn't think to mention that before?", Eda scolded.

"Didn't you think to ask before?", King retorted.

"Enough! This is no time to argue!", Lilith urged.

"You're right. We have to speed this up!", Eda urged right before noticing the Were-Oni's vines headed for her and catching them.

"Nice try, Owl Lady.", the Were-Oni discouraged before she then flung her toward Lilith, knocking her out.

Then, King stepped in and let loose a sonic roar at the Were-Oni, who was undeterred by this, leaving him surprised.

"Weh?", King puzzled.

"If you were trying to blow me away with a sonic roar, you need a lot of work with this one.", the Were-Oni sneered before then grabbing King with a vine and tossing him away toward Eda, Lilith, and Hooty.

"King!", Luz shouted before the Were-Oni grabbed Luz and hovered her above her head.

The Were-Oni was now getting ready to devour Luz.

"Amity! Amity, please don't! Amity, it's me, your girlfriend! Please don't do this, sweet potato. Please…!", Luz sobbed softly.

"Hate to disappoint you, but I have a feast to finish. Soon, even your sweet potato will be gone... Forever.", the Were-Oni discouraged.

Hearing this broke Luz's heart.

"Please... No!", Luz sobbed.

The Were-Oni then roared as she opened her mouth, about to swallow her whole as Luz sadly braced herself. After a moment, though, the Were-Oni started grunting as if struggling, worrying Luz, who opened her eyes, and turned to see the were-oni seemingly convulsing as she was now moving away, much to her surprise and shock as she gasped in hope.

"Okay, what the heck is going on here?", Eda asked.

"Something must be happening that's weakening the demon's grip on Amity.", Lilith guessed.

"So that means.. Amity's fighting back!", King realized.

In response to this development, Luz shed tears that replaced despair with hope.

"That's it! Come on, Amity! I know you can snap out of this. My brave and sweet sweet potato.", Luz encouraged.

That was the final push needed. Soo, the were-oni roared in distorted agony as said roar changed back into Amity's voice once more with not only the demonic spirit exorcised from her mutated body, which collapsed as she groaned in exhaustion, but also several magic trails, which all flew back to their original owners, revitalizing them back to the peak of their health such as Willow & Gus, who gasped while they sat up and became relieved as did Camila, Hunter, and Alador, the 3 gremlins, the witch in a coven scout uniform sans mask, and even the 3 former Coven Heads. The demonic spirit hissed angrily, making everyone gasp for a moment before glaring angrily.

"NO! I need more...!", the Demon spirit hissed.

"Away with you, foul spirit! WEH!", King shouted, blasting away the demonic spirit, blowing him away like the wind.

"Luz NOCEDA!", the Demon spirit shouted.

The Evil Soul was finally driven away seemingly into the sky by King's sonic shout.

"AND STAY OUT! Hoot!", Hooty scoffed.

Of course, there was still the matter with Amity. Luz rushed over to her out of worry.

"Amity!", Luz called in worry.

Amity, or rather, WereAmity, groaned as she did all she could to stand up herself and slowly fluttered open her eyes, which are now in a lighter shade of lavender with her black slit pupils, which saw a concerned Luz and co.

"L-Luz…? Luz!", WereAmity spoke excitedly, the Were-Oni quickly hugging Luz in joyous relief.

"Oh, thanks for helping me out there! I nearly ate you guys…", WereAmity thanked.

"Uh... Amity? You're crushing me..!", Luz groaned in pain.

WereAmity, realizing this error, saw for herself and gasped, setting Luz down.

"Sorry, sorry!", WereAmity apologized.

"Hey, don't sweat it, sweet potato. We're all just glad that you're all you again. Well, on the inside, anyway...", Luz gestured.

WereAmity then saw her mutated, obese, lavender were-oni body worriedly.

"But I don't get it... That spirit was forced out of me. So..., why didn't I change back? And what was the other stuff flying out of me?", WereAmity asked.

"Let me, uh... read the book a little more.", King said, inspecting the page and then widened his eyes.

"Oh. Well, I have good news and bad news. The Bad news is, apparently, while a demonic spirit can be permanently driven out and banished from its victim's body through the remembrance of love, or a deep emotional connection to someone else, it can't undo the transformation curse that happens every night. But the good news is, when you forced that demonic spirit out of you, you also returned their respectful magic back to the witches.", King responded.

"Huh. Well, this is all well and good, but how do I get uncursed?", WereAmity asked.

"Unfortunately, it says there's no known cure.", King said sadly.

"Oh, no...!", Luz groaned in worry.

WereAmity grew worried from this, especially seeing her upset after what just happened, and then to herself, checking her new form out for a bit.

"You know what, Luz? Maybe being a huge, fat were-oni isn't so bad after all. That is, as long as there's no demonic spirit possessing and using your body at night or anything.", Were Amity smirked.

"Really?", Luz asked,

"Yep. But if you want, I could help you change into a big, fat, voluptuous were-oni, too.", WereAmity replied, shaking her fat body in a sexy way to entice Luz.

She blushed madly with widened eyes.

"Oh... my... okay!", Luz blushed.

But given the chaos that just ensued, Eda, King, Lilith, and Hooty weren't thrilled.

"Are you crazy, or are you crazy?!", Eda glared.

"You just sucked up their magic!", King scolded.

"You nearly tore everything up!", Hooty added.

"We have no idea what would happen to her if you go through with this!", Lilith shouted.

"Actually, I think we're in the clear.", King assured, reading the entry he once made.

"Really? Well, how can you tell?", Eda asked.

"It says here that while were-oni mostly prefer demonic spiritual possession to get the transformation done to rain down terror, chaos, and even death, some use a different method if they just want to reproduce, or if they're just going through puberty. Like some kinda rite of passage? And that method works by either biting someone or scratching them.

"Oh...", Eda, Lilith, and Hooty spoke in awe.

"Well, when you put it that way...", Eda began before blushing at the thought of what it'd mean for Luz.

Then, WereAmity turned to the others.

"So, uh, guys, with all this in mind, could you guys, uh... clear the room?", WereAmity blushed.

"Say no more, wereboots. We gone.", Eda assured before she quickly got everyone out of the alleyway and back home.

With the coast clear, WereAmity turned to Luz with a smirk.

"Actually, I think I have a better place in mind. Scoop.", WereAmity smirked, picking Luz up before the two then took off.

"Oh, wow..! Were-demons!", Luz squeaked in surprise before Were-Amity jumped away.

With one jump, Amity, along with Luz, landed near the Grom Tree.

"Whoa. You jump nice, Amity.", Luz grinned.

"Thanks, Luz.", WereAmity grinned.

"You're welcome.:, Luz grinned.

"So... about this being turned into a were-oni thing. Are you sure you wanna go through with this?", WereAmity asked.

In response, she held up her arm, insisting that WereAmity bites her.

"I've never been more sure of anything in my life.", Luz responded.

"Uh..., okay. If you insist...", WereAmity said.

With that, she cautiously bit Luz in the arm, making her wince once she bit hard enough

"Ow...! Okay, okay! I think that's enough, Amity..!", Luz shouted before WereAmity opened her mouth and moved it away from Luz.

"Are you okay?", WereAmity asked.

Just then, Luz started to feel heavy and moaned a bit.

"Well..., I am starting to feel heavy.", Luz explained.

Then, she started to sweat all over.

"Come to think of it, I... I am starting to feel hot. Almost like I'm burning up...", Luz said, nervously giggling as her teeth turned into fangs.

Once the feeling subsided, though, she became shocked, if not in awe as well, from seeing her hands swell and inflate while her skin started turning dark purple with her nails growing into claws, much to WereAmity's surprise.

"Wow... I can't believe this is happening...!", Luz spoke, a bit amazed.

Then, just like before with Amity, Luz's butt suddenly started to grow bigger, making her pants tighter.

"Look how big my rear's getting...!", Luz moaned.

Luz's butt only kept growing bigger until her pants ripped off completely first, and even then, it was still growing.

"Hey..., this is starting to feel pretty good.", Luz grinned before, a moment afterward, her underwear snapped off and ricocheted toward one of the tree branches, making Amity and Luz blush completely red again, but this time in an embarrassment of joy. Suddenly, Luz started convulsing and shuddering in overwhelming pleasure from the transformation in equal shares with the pain, making it bearable, at least.

"Whoo! I never knew it'd hurt this good...!", an ecstatic Luz moaned.

As fun as her transformation was starting to feel, though, Luz's metamorphosis from human to were-demon was not an easy one. Luz grunted and mewled as her feet grew, causing her shoes and socks to burst. Right after that, her legs swelled up and enlarged; not to mention that her arms swelled up, too.

"Ahhnn! Yes...! I can feel myself... getting thiccer!", Luz yelled in ecstasy.

Not unlike with Amity, her body grew larger up to 12 feet in height and 6,000 pounds in weight while her normal human ears ears grew longer and became horn-like in appearance.

"Ohhhh, yeah...! I-I can feel myself growing bigger...! And larger...! And I don't think I can stop...! I don't WANT to stop! I just wanna keep growing...! And growing...! Until I...! I-AAAAAAAARRRRRROOOOOOOOOOO…!", Luz howled with a moan as her belly and breasts expanded outward and swelled up, finally ripping her clothes apart completely and becoming exposed to the air, its briskness causing her nipples to harden.

WereAmity was in complete awe over what had transpired. Once the metamorphosis was complete, Luz took deep, heavy breaths, feeling her new body with her enlarged, demon hands, especially with her eyes closed before giving a lust-filled, sultry chuckle toward WereAmity as she lifted her face up.

"All right, Batata... How do I look now?", the plump, sexy demoness smirked as she opened her eyes, which are now no longer her usual brown eyes, but instead, a completely bright purple with black slits.
