Tsuyu Asui, Momo Yaoyorozu and Kyoka Jirou entered an abandoned building and looked around with flash lights before a shadow quickly moved past the beams of light. They looked around before the three of them were pushed back with a forced and pinned to the wall. They looked up and saw a pair of glowing green eyes staring down at them, "Who are you three? Why have you come here?" the three began gasping for air before they fell to the ground with a heavy thud, "Now…I'll ask again, who are you and why have you come here?"

Shining their lights up, they saw a pale boy around their age staring at them with narrowed eyes and his arms crossed, "Well?"

"We can ask you the same," Momo coughed, "This place is abandoned…we decided to go exploring a little and-"

"This place is technically not abandoned anymore. I've been living here for about six months give or take," the three looked at him in confusion, "But I'm sorry, where are my manners? My name is Izuku Midoriya,"

"I'm Kyoka Jirou and these are my friends Momo Yaoyorozu and Tsuyu Asui," Kyoka said in an emotionless tone, "And…you said you've been living here for about six months?" Izuku's eyes widened and a frown slowly formed across his lips, "What happened? Are you a runaway or something?"

Izuku turned his back towards them and Tsuyu tilted her head to the side in confusion, "Are you hiding? What happened?"

"I-it's a long story," Izuku turned back around and slowly opened his mouth, revealing a pair of fangs. The girls quickly stepped back, pressing themselves against the wall as Momo held her flashlight up above her head, ready to swing, "That won't work…it might hurt only slightly, but you'll be destroying your light,"

Izuku sighed and sat down before he stared up at the ceiling, "Your heartrates…they're going through the roof. Please try to calm yourselves down before I do something I don't want to," he looked back down as the three continued to stare at them, "I'm not going to attack you three,"

"And how can we trust you?" Izuku held his hands up and looked down, "You're one of the undead and-"

"And thank you for pointing out the obvious," Izuku shook his head and looked up again, "To be honest, I haven't gone after a single human, even though there are a few who rightfully deserve it, I just met you three and outside of trespassing in my home, you really haven't given me a reason to want to kill you,"

He stood up and began walking away, "You can leave if you want, or you can stay. I was just about to hunt for some mice," he looked over and saw the three giving him disgusted looks, "Hey, mice are very nutritious believe it or not…at least…they are for Vampires," he turned back around and began walking away while Momo, Kyoka and Tsuyu hesitantly sat down and began looked around the decrypted room.

Tsuyu and Kyoka looked at Momo, who frowned and hung her head, "Well what should we do?"

"We're going to…we're going to-" Momo inhaled slowly and shook her head, "We're going to stay for a while…his little act…we're all shaking and if we run out of here in a panic, we'll get in trouble for being here and he'll just transform his body into a mouse and everyone will think we're lying about him." Tsuyu and Kyoka hummed and slightly nodded as they heard footsteps coming from down the corridor.

Izuku soon returned and sat back down with his shoulder slumped over and his head hung down, "I told you that you were more than welcome to leave. I'm not forcing you three to stay here,"

"And you said we can stay if we wanted," Kyoka crossed her arms, "And right now we don't feel like getting into any trouble," Izuku hummed and shrugged his shoulders before leaning back and the room fell completely silent.

Hours slowly passed and Momo, Kyoka and Tsuyu began yawning, "Why don't you three try to get some sleep," they looked up at the undead teen and Izuku took a deep breath, "Well, from the looks of it, you three aren't nocturnal like I am, and you shouldn't force yourselves to stay awake,"

"You'd like that, wouldn't you?" Momo narrowed her eyes, "You'll kill us while we're asleep and-"

"If I haven't killed you yet, what makes you think I'll kill you in your sleep?" Izuku questioned, "Look, if you're feeling uneasy about that, how about two of you sleep and one of you keep watch? In a few hours, the one who's keeping watch can wake one of you up and switch," they looked at him and Izuku shook his head, "Are you can force yourselves to stay awake and eventually pass out from exhaustion, that's an option too," Kyoka and Momo crossed their arms before leaning forward, resting their heads on their arms while Tsuyu looked at the undead teen with wide eyes.

Izuku tapped his fingers on the surface of a dusty table, "Midoriya?" Izuku hummed and looked at her in confusion, "If you don't mind me asking, are you a born Vampire?"

"Well…that's rude," Tsuyu slightly frowned and Izuku chuckled and shook his head, "I'm kidding, I'm kidding…to be honest, I'm not a born Vampire. How this happened is pretty boring, and I don't want to get into it,"

"Well I'm going to be up for a few hours," Izuku frowned and Tsuyu crossed her arms, "So what happened?"

"Heh…whatever…I was out partying with two of my friends a few months ago," Izuku sighed and Tsuyu arched a brow, "Well…my friend, Ochako Uraraka…she said that she heard something coming from around the corner and our friend Tenya Iida and I went to check it out. We saw a pair of glowing eyes and then the next thing I knew I was on the ground shaking.

When I came to, I looked up and saw Uraraka staring at me in shock with Iida standing in front of her, looking at me like he was itching to kill me. I felt this strange urge to kill them, but I ignored it. Uraraka screamed in terror and she and Iida turned and began running away from me. Confused, I stood up and looked down, still a little shaky.

I looked around before I began making my way home. When I got there, I saw Uraraka, her parents, Iida, his parents, his older brother and my parents waiting for me. Originally, I thought Uraraka and Iida went to our families and they were there to make sure I was okay."

He paused for a second before sighing and shaking his head, "I was wrong. My dad grabbed his pistol and claimed it was loaded with silver bullets. My mom had garlic cloves in her hand while everyone else had Holy Water. Before I knew what was happening, I saw, or didn't see my reflection in the mirror and I saw what was happening.

I turned and ran out, but not before feeling some Holy Water splash my arm…it burned and I howled in pain. I looked back with pain behind my eyes, hoping they were just joking, but I saw that they weren't, that they were actually setting me up for death. I fled and came here. I've lived off the mice and spiders that call this abandoned building home."

The air between them grew still, "I don't expect you or your friends to believe me, Asui, and that's fine,"

"That's messed up," the two looked back and saw Momo and Kyoka sitting up, "So something happened that was out of your control and your own parents wanted to kill you?" Izuku frowned and nodded, "But why? This could've happened to your friend Iida or Uraraka and then what? And why did you have the urge to kill your friends like that?"

"I don't know and…it's kind of difficult to explain, but if a person is…how do I put this…if a person is turned by a Vampire, and they wake up…they're going to be like a newborn and their hunger will be high. So high that they'll attack the nearest food source, which would've been Uraraka and Iida, I fought the urge and that's what happened. Technically I'm being hunted by the ones who did this to me, but I'm not too worried about that,"

"And why's that?" Kyoka question and Izuku hummed, looking at her in confusion, "Why are the ones who did this to you looking for you?"

"To join their Clan…it's kind of like packs and Werewolves. Since I left, I'm considered a runaway with them too and they'll kill me. But I've made a living here. I get all the mice and spiders I can eat, I don't have a care in the world, and so far, the only ones who know I'm here are you three. Everyone else is either too scared or uninterested in coming into this building."

The air grew still as Izuku stood up and sighed, "You three should get some sleep. You have my word that I will not try and kill any of you," the three stared at the undead teen as he began walking away, "Or stay up, whichever makes you comfortable,"

The three looked at each other before taking deep breaths and laid their heads down on their arms before slowly drifting off to sleeping.

Okay, as I said, I want to thank nightmareking for allowing me to borrow some ideas from his Vampire story. I've put some thought into this and talking to my group of advisors and they actually believe it'll be a better idea to give this its own story. Like most of my stories, this is rated for a list of reasons and obvious AU. Please enjoy everyone and please let me know what everyone thinks.
