DISCLAIMER: I DO NOT OWN OWARI NO SERAPH.
Note: Advanced apologies for the OOC's.
Summary: AU. Yuu and Mika got separated on their escape and reunited years later. Mika wants Yuu to join the vampires and Yuu wants Mika to join the humans. Mika discovered that one person is holding Yuu to be with the humans and it's his goal to kill her.
So I'd like to sum up some changes here. So Yuu and Mika still got the same background until the part where Yuu escaped and Mika got left behind and became a vampire. Yuu grew up with the humans under Guren while Mika was with Ferid (although Mika still drinks only Krul's blood). I was only able to watch season 1 of the anime and read bits and pieces of the manga from chapter 12 until chapter 14. So those are my only references and if anything goes wrong, sorry.
Yuu and Mika are best friends, yeah. Also... IF YOU ARE A YUUxMIKA shipper, please take note that THIS IS NOT A YUUxMIKA fanfic. So let's be clear on that.
The fic will focus on Yuu, Mika and Shinoa. Not a love triangle.
SERAPH: THE BEGINNING
The world was infected with an unknown virus, there was chaos everywhere and amidst the abomination, vampires took advantage of this and started to take surviving children that weren't infected with this virus. Among them was Yuichiro Hyakuya.
It's been years since the tragedy that every one was killed by Ferid. Yuu was now part of Shinoa's squad with the mission to annihilate vampires and save people.
The small squad led by Shinoa were walking by Shinjuku, doing their casual patrols. It was the same fateful day where Yuu was about to reunite with his best friend.
"I can't believe we took this area to patrol." Kimizuki muttered.
"That's because our leader sucks not only at janken but is also cursed to have gotten this area in the simple draw lots!" Mitsuba exclaimed in irritation. The two turned to Shinoa who was walking with her head held high and her stupid grin plastered across her face.
"You're not going to apologize, are you?" Kimizuki asked.
"But this is also not a bad idea." Yoichi said in their leader's defense. "There are a lot of people here that we can save."
"And a lot of vampires we can kill!" Yuu added.
"Yes but this is also a big area where we don't know where to find anything." Mitsuba informs them, in case they were unaware. Shinoa grinned at Mitsuba, annoying the girl. She was literally not saying anything but her grin was enough to translate what was on her mind. "Quit it! There's nothing going on between me and Yuu!"
"I didn't say anything." Shinoa says with a shrug.
"Like heck you didn't!" Mitsuba shouts at her.
"Well whatever, I would ask to be transferred when the time comes. That way we don't have to worry about these kind of things." Kimizuki stated and he receives a slight punch in the gut.
"Lieutenant Colonel Guren will do worse if you were on his team." Shinoa tells him, that smile of hers still there. Kimizuki shivered as he imagined Guren beating him for no reason.
He turns away from the small leader with a frown. "You freakin' demon." he muttered.
"But is it really possible to leave a squad and go to a different squad?" Yuu asked, curious if it was possible. He likes everyone in his team but it'd be nice if he were to get a chance and be with Guren.
"When you get promoted I think." Yoiochi replied. "Or if a higher up recommends you."
"Or if I say so." Shinoa added with a matter-of-fact tone.
"I wouldn't depend on your recommendation." Yuu mumbled, remembering how she spread his score to the whole humiliated him.
"By the way, if ever a comrade were... let's say, in a pinch, what do we do?" Yoichi asked.
"Obviously we go back and save that person!" Yuu replied but Shinoa clicked her tongue. "What?"
"Guren explained this to us already but no matter what happens, we will follow what the leader commands us to do." she says. "If we're ordered to retreat, we run and no one looks back. If we're ordered to attack, then we attack we all we've got."
"Easy for you to say! You're the leader!" Yuu shouts at her and she beams at him.
"Exactly."
They stopped on their tracks when Mitsuba, who was in front, halted. Yoichi traced Mitsuba's gaze, seeing a vampire with blonde hair at a distance. "Look over there." Mitsuba says, pointing at the fellow on the other end.
Jokes aside, they all wore their serious gaze and prepared their weapons for a fight.
"Do you think he's baiting us to approach him?" Kimizuki asked, his eyes never left the vampire.
"Only one way to find out." Yuu says and took the courage to step forward. But Mitsuba grabs his arm to stop his movements.
"You're not flying solo again, you hear me?" Mitsuba reminds him and he nods. The two locked their eyes at each other for a moment when Mitsuba realized that she was still not letting Yuu's hand go. She blushed and released him from her grip and he started to approach the vampire with caution.
The girl remained blushing until then. She could feel an evil grin from behind her where Shinoa was positioned.
As Yuu got closer to the vampire, he noticed that the vampire was bleeding. He's wounded? He lowered his guard a bit as he walked even closer, until the vampire lifted his face up and they caught each other's gaze. Yuu froze and so did the vampire. Mika... No... how is it possible? He raised his walls again and stopped walking, wary of the Mika look-alike.
"Who are you?" he asked. But the words that came out of the vampire's words surprised him.
"Yuu?" the vampire said. "Is that...?"
"Mika?"
On the watch for Yuu and any suspicious movement from the vampire, they were getting impatient. "What's Yuu doing?" Mitsuba wondered.
"I think the area is clear." Yoichi said as he came back from his scouting with Kimizuki. "He's alone."
"And he's wounded. Yuu can kill him in one swing." Kimizuki added. But Shinoa's eyes were glued to the two boys in front. Noticing that Yuu's guard was down and the vampire seemed emotional from where she stands.
She thought that maybe the vampire was a friend of Yuu's in the past but it was impossible.
When she saw the vampire shed a tear, her suspicions were confirmed. "He's crying!" Mitsuba exclaimed. "Hey, what's up with that? Should we kill him?" she asked but her leader did not respond. "Hey Shinoa! You listening to me?" she turned to her leader to see that her eyes were still on the two. "Hey!"
"I think... he's not a bad person." she muttered, lowering her own weapon when she saw Yuu lower his.
Yuu hid his weapon and catches Mika from falling. Slowly, Yuu knelt down to place Mika's head on his lap. "Everything's okay, Mika." he says. Then he turned to his comrades. "It's okay, he's not an enemy! He's my friend!"
When Yuu turned back to Mika, the vampire gripped on his hand.
"Don't trust them, Yuu. They are deceiving you. They are using you." he says.
"It's okay Mika, they won't hurt you. They're my friends. We'll take you home and we can talk. We just need to get your wounds treated and-" but then he saw Mika's fangs. And the clothes he was wearing. He almost forgot but earlier he thought Mika was a vampire. "Mika... you..."
"This isn't your fault."
"You need blood don't you?"
Yuu's comrades joined him and Mika sat up in a hurry, glaring at the humans that he believes are using Yuu for something terrible. Just like what he was told. Yuu pulled him back from attacking though.
"Yuu, they're-!"
"It's okay, Mika. They won't hurt you." Yuu wanted to calm him down. Mika's heart was racing, his eyes studying the four humans before him. How he plans to tear them to pieces and run away with Yuu.
"Of course they would! I'm a vampire and they're humans!"
"If you're Yuu's friend from somewhere then we'd understand." Yoichi says, hoping to help the vampire trust them even just a bit.
"Yuu, please come with me." Mika turned back to Yuu, grabbing his coat. "It's too dangerous to be here. Please..."
"Mika..."
Without warning, Mika pulled Yuu close to himself and got back to his fee and not letting his friend go. Kimizuki stomped towards them to interfere with whatever the vampire was planning. With one kick from behind Kimizuki, he stumbled forward. After kicking him, Shinoa pushed Mitsuba towards Yoichi and the two collided, the space in the center was empty as a vampire smashes his fists in the ground.
Kimizuki watched Mika drag Yuu with him towards the city and gritted his teeth.
"Yuu!" he shouts.
Along with the redheaded vampire were more vampires that appeared from the shadows, surrounding them.
"W- What's going on? They weren't around earlier..." Yoichi muttered in fear. Mitsuba rolled off him and armed herself for a fight.
"Get up! It looks like that Mika person lured us in after all!" she says and Yoichi nodded at her. Mitsuba turns behind her to see Kimizuki chase after Yuu and Mika while Shinoa's back was facing hers. "Hey, order us around will you?! We're gonna attack!"
But after shouting, she realized Shinoa hadn't brought out her weapon yet and that she was just standing there.
"Shinoa!" she shouts.
"Retreat." Shinoa mumbled. Slowly facing Mitsuba. "Run as fast as you can and don't look back." she instructed.
Mitsuba saw blood drip from the injury on the side of Shinoa's head and the redheaded vampire cracking his knuckles from behind. She was seized with fear when it felt like it was the end. She was facing a life and death situation. She knew that the moment she stepped on the battlefield but the moment it's actually happening, she would realize that she doesn't want to die.
"RETREAT!" Shinoa shouts this time and Mitsuba snaps back to reality.
Yoichi grabs Mitsuba by the hand the two run off towards the layers of vampires with the fewest number.
Yuu on the other hand was resistant as Mika dragged him off the battle but Mika also won't budge. He will not let Yuu go back to the ambush.
"Let me go Mika! My friends are back there!" Yuu screamed. "Did you do this?! Did you purposely use yourself bait to ambush us?!" he shouts angrily. "HUH?!"
"You don't understand. This is a rescue mission." Mika explained to him and kept his grip on Yuu's wrist. But Yuu yanked his hand back and pushed Mika away in anger. "I am rescuing you from them!"
"You'll get my friends killed!"
"But I'M your friend!" Mika reminds him.
"You are but so are they!"
"You have can't have both Yuu! Humans and vampires will always be at each other's throats. That's why let's just run away together and let them do as they want! I offered to be bait and save you, in return to their cooperation, they can take those humans with them!"
"Like I said they are MY FRIENDS! How could you do that?!" Yuu pushes Mika away in anger and was about to run back but he sees Kimizuki panting when he finally caught up with them. "Kimizuki, where's everyone else?"
"I came to make sure you return home with us." Kimizuki tells him. "Yoichi and Mitsuba ran towards the other direction."
"And Shinoa?"
"Last I saw her she's facing a noble." Kimizuki hesitated to say. "Yuu, we were ordered to retreat. No one runs back."
"Yuu..." Mika tried to reach out to his friend.
"How could any of you not think of going back when our team captain needs help?!" back then... he remembered how helpless he and Mika were when they were against Ferid. They were so helpless that Ferid played with them for fun. And the other kids were killed in the process. Right now... there may not be a chance for Shinoa to even beat that noble even with her skills.
"We'll all die if we go back and you know it!" Kimizuki knew that of course but if they were to come back... then they'd all die. "Let's have faith in her. That arrogant little girl will not let a vampire push her around."
Yuu felt a hand touch his shoulder and he swats it away. Mika was frustrated now that Yuu doesn't seem to give in to his proposal.
"Why?! Why would you choose a life like this?! With the humans!?"
"Because I'm a human. And so are you, Mika." Yuu tells him. "If you don't want to help that's fine. But don't ever betray me or my friends again."
The moment he said that, he runs back to the battlefield with Kimizuki backing him up. Mika was left, thinking... why? How could Yuu still choose them? Those humans? Doesn't he get it? Or did the humans brainwashed him this far to believe in them?
No! It was that girl from earlier! It was her who was holding him back... isn't it?
Yuu... I just wanted to... I...
