When Izuku had wished that he could getaway from home for a day, this is not what he meant. He went to bed in his apartment and when he woke up, he was chained in a-

-castle dungeon and made the personal servant of it's ruler, Katsuki Bakugou. King of the Vampire Kingdom of Chinokawaki. That was a year ago and as far as he knew, Izuku was the only human in a land of vampires, ghosts, and other creatures.

"Get over here, meatbag!"

Izuku rushed over to King Katsuki's side. Katsuki shoved a scroll into Izuku's hand.

"Take that to the Draculain Chapel in town."

Izuku bowed politely and nervously.

"Yes, your majesty."

But before Izuku could leave, Katsuki grabbed his wrist tightly.

"And if you so much as-

-try to remove that enchanted necklace, I will not hesitate to have every vampire in this kingdom hunt you for sport, do you understand?"

Izuku gulped before nodding.

"Now go. Dinner is in 2 hours and I want back here and prepping dinner 30 minutes before then."

Izuku rushed through the castle, making his way into town. The kingdom was always in a perpetual state of nighttime and seeing the sky made Izuku miss the sun. The birds. The white fluffy clouds. He missed his home. While walking through the town, he overheard some of the-

-townsfolk talking about a rogue group of Vampires that had stolen many spellbooks from the chapel and the castle, but Izuku continued onward towards the chapel.

Upon arriving, he used the giant knocker on the chapel door. The door opened and the chapel's-

-priest, Shota Aizawa, answered.

"Hello, Lord Aizawa. I've come to bring this scroll to you from King Bakugou."

Izuku handed Aizawa the scroll.

"Thank you. Give the king my regards. Have a pleasant evening."

Izuku bowed. Aizawa was one of the few vampires in the kingdom that-

-treated him nicely so Izuku never minded visiting the chapel. But lately, Izuku couldn't help but feel like he was being watched more than usual.

He decided to quicken his pace to return to the castle. However, Izuku tripped over a tree root on the outskirts of the town and saw what looked like a bat flying towarss him, before turning into a vampire as it passed the tree.

The vampire approached Izuku, his eyes an bright, piercing blue and his hair white. Izuku tried to get up to escape, but instead of the vampire attacking him, he helped him up.

"Are you ok?"

"Y-yes, sir. Thank you, but I really need to get back to the castle."

"Why? So the bastard of a king can flaunt his human trophy?"

Izuku remained silent.

"I know we just met, but you don't have to go back. There are people here who can save you?"

"Like who? I can't go home. I don't have any powers here. No garlic. No wooden stakes. No holy water. How can I even escape the town?"

"I can help. I know people. People who specialize in the type of magic to send you home. It's kind of our fault your here in the first-

-place, anyways?"

Izuku looked at the man, confused.

"How so?"

"My friend, Himiko Toga was the king's royal sorceress. She specialized in blood magic. Bakugou had requested a spell to open a portal to another realm in an attempt to expand his kingdom.

What he didn't know was that I had heard his plan when I was surveying the castle in my bat form. I convinced Himiko to tamper with the spell to make it ineffective, but instead of destroying the spell, it had a different effect. It brought someone from that realm here.

It brought /you/ here."

"W-what? But why keep me alive? What about your friend?"

"When the spell backfired, the king ordered for Himiko's execution. However, my band of rogues manage to escape with her, but not her spellbook. So we've been trying for months to get her book-

-and the materials. But now we just need one more thing. You. We can send you home."

"How can I trust you?"

The man sighed.

"Lord Aizawa has been housing my group in the catacombs of his chapel. Trust me. I mean no harm."

Izuku was reluctant. Very reluctant.

But if what he said is true, then he had to try.

"Ok... I trust you..."

"Thank you. My name is Dabi, by the way."

"Izuku."

"Ok, Izuku. I'll meet you at the church. Hurry. We can't waste time."

Dabi turned back into a bat and flew to the town.

Izuku followed soon after, making a beeline for the chapel. He used the giant knocker again and Aizawa answered the door.

"Dabi must have talked to you. Come inside."

Aizawa led Izuku into the chapel where they went to the coffin in the center of the altar.

Aizawa then pressed a hidden button inside if the coffin that revealed a secret passage into the catacombs.

"Hurry, child. I can keep you guys covered, but not for long."

"Thank you, Aizawa."

"Be safe, kid."

Izuku then climbed down into the catacombs, where Dabi and a red-

-haired vampire that Izuku met at the castle, were waiting.

"Kirishima?"

"Hey, Izuku! Surprised?"

Dabi smacked his head.

"Don't waste time. We have to get him back to his realm."

Dabi then grabbed Izuku's hand.

"This way."

The three made their way into a massive room within the catacombs, where a blonde girl with a floating boom was standing in front of a cauldron.

She turned to see the three.

"Ooh! You must be Izuku! You ready for your journey home?"

Izuku nodded. He then realized he was still-

-holding Dabi's and quickly pulled it away, blushing badly.

"Go, Greenie."

Izuku approached Himiko and noticed she was holding a ceremonial dagger.

"Hold out your hand, please."

Izuku nervously complied. She then swiftly swiped the dagger across his palm, but there was no-

-injury.

"What the...?"

Dabi looked confused.

"What's wrong?"

"The dagger didn't cut! That bastard must have used some spell or magic to ensure his blood can't drawn!"

Izuku then thought back to what Katsuki had said to him before. The necklace. It was enchanted.

"Let me-

-see something."

⚠️CW: Use of knife and blood⚠️

Izuku then removed his necklace before grabbing the dagger and cutting his palm, this time, successfully."

Himiko smiled.

"Amazing! Now just spill some into the cauldron!"

Izuku did as he was told and upon adding the-

-blood, the cauldron started shaking violently. The cauldron spilt on the floor and the liquid for a portal to Izuku's world.

"You really thought you could escape?"

The group then looked to see Katsuki standing behind them.

"Now now, Deku. Stand aside and I'll spare these...-

-sorry excused for vampires. Let them experience my expanded kingdom."

Izuku remained silent as Dabi guarded him.

"Back off, asshole. He's going home. And you're staying here."

Katsuki chuckled as he elongated his fangs and nails to form claws.

"Prepare to die!"

Katsuki charged at the group, before being slammed against the wall by Aizawa, who managed to hear the commotion.

"How did he get passed you, geezer?!"

Izuku looked sullen.

"It must have been part of the enchantment. He must have transported here once I removed it."

Dabi looked at him with concern, and then at the portal, which was closing slowly.

"Shit. You have to go!"

"No, you're all gonna go! He's not just after Izuku now! He'll be after all of you!"

"Like hell, old man!"

"Do not argue with me!"

Aizawa then grabbed Kirishima and-

-tossed him into Himiko, forcing them both into the portal. Izuku then grabbed Himiko's spellbook and grabbed Dabi's wrist.

"We have to go... Dabi, please."

Dabi looked at Izuku and then back at Aizawa, who was in a heated battle with Katsuki.

"...Okay..."

Izuku and Dabi rushed into the portal just as it closed and Katsuki couldn't help but yell in frustration. He grabbed Aizawa by the neck, dragging him back to the surface, where Katsuki's guards had waited.

"Your majesty, what are your orders?"

"Throw this traitor-

-in the cell. He won't see the moonlight ever again."

The guards restrained Aizawa as they took him to the castle.

Back with Izuku, he and the three vampires all looked up to see a room unfamiliar to them, except for Izuku.

"This is my apartment... I'm home... I'm really home."

Izuku looked at the window to see it was nighttime. Himiko looked up and noticed something weird about Dabi and Kirishima.

"What is it, freak?"

Himiko could only point at a nearby mirror. They had reflections.

All three of them approached the mirror and noticed a few more things, most noticeably, they no longer had fangs, nore could they really smell Izuku's still bleeding hand.

"I wonder if that spell turned you into humans. As a way to make sure you adapted to whatever realm-

-you're in?"

Himiko grabbed her book.

"It's possible. Which means the king's invasion would have possibly failed."

"But why was Izuku still human if he was in a world of non-humans?"

"No idea. I'm a sorceress, not a genius."

Kirishima then interrupted.

"So... what now? We're in a realm we know nothing about."

Dabi then pointed at Izuku.

"You do realize that this hot piece of ass is from here, right?!"

"Dabi!"

"Calm dowm Greenie. I'm mortal, now. Kinda have a limited amount of time to get with-

-you."

Izuku couldn't help but blush at Dabi's remarks.

"You didn't have to word it like that..."

"Calm down, Greenie. We can take it slow, 'kay?"

Izuku smiled nodded.

"I promise I'll teach how my world works, too. But first, I'm exhausted. I'm sleeping."

Izuku went to his room and crashed on his bed, with Dabi following to comfort him. Toga and Kirishima sat there, confused and bored. Kirishima then turned to Toga.

"Sooo... what now?"

Toga simply shrugged her shoulders, unsure.
