When the War is Done What Do We Do?

Chapter One: When the Flag had Risen

January 6th, 2024

Hard to believe I'm going to be 20 years old this year. It's funny, really. When I was first born my parents tried to kill me and I was sent to an orphanage. There I had no interest in becoming anyone's family but it felt like as time went by and after the Seraph of the End took to effect allowing the vampires to take hold of the country I became...closer to them. Even then, after losing them to that despicable noble, and my brother being turned into those horrible creatures, that I vowed never to trust or have anyone come close to me again but that failed after I met my new family. The first one is a real troublemaker and used her power to keep me in line while I studied to fight for myself. The next one seemed like a real loser but his kindness is something not everyone had but wanted. The third one, oh boy, is he a real walking telephone. Not even the first time we meet and he beats me to a pulp. Finally, the last one really felt like she was really leading her own squad. Was she angry when she found out who was going to be in her squad. However, it's thanks to these guys that I was able to know what it was like to have a family again and the need to really protect it.

It's been a few years now that I became a soldier and already there was betrayal and the lost of a close family member. He was the first one to take me in. Did he exploit me? Yes. Did I care? Not as long as I was able to help and defend my family. But now he's gone; killed by the hands of the same vampire noble that killed most of my family. The only people I can trust now are my new family and a former vampire queen (who I still have doubts about).

I should finish this up soon. Tomorrow we move out and crush the vampires once and for all. Then maybe...just maybe...we will have true peace.

Private First Class Yūichirō Hyakuya (百夜 優一郎)

Yūichirō placed his pen down and slowly closed his book. The small lamp on the rock he was hiding underneath gave off a faint hint of light, but it was enough to help him write. He was given instructions, along with everyone else, not to give away their position, even if it meant freezing in the cold winter.

Further down the destroyed road he was positioned, to his right, he could barely make out Kimizuki hunkered underneath a tipped over car. He was using the seats as a pillow, which made Yu a little jealous.

"Bastard, how come he get's the good spot?" He thought to himself.

Further away from Kimizuki was Yoichi and, although he couldn't see him in the night, he could tell that his friend was just as nervous for tomorrow as anyone else. He was partnered up with Major General Shinya Hiragi. Both were to watch for any surprise attacks from the rear.

Opposite from those two, on Yu's left side, Mitsuba was hiding inside one of the many abandoned buildings that were nothing more than caves from the aftermath of the virus. Yu could see her tiny lamp lit for the warmth but it quickly vanished after a small gust of wind passed by.

Ahead of her was Shinoa, his squad leader. He could never really tell what she was thinking and it didn't help that she wasn't being truthful with any of them. The mission they were about to embark could cost them their lives yet they were only told to enter the capital under the smoke of the fight between the Moon Demon Army and the vampires. Along with her was a new member they had joined who lost his squad during a trap mission, Makoto Narumi.

"Yu, are you cold?" A voice asked.

Yu turned to see his oldest family member, Mikaela holding a blanket out for him. Behind the young vampire was the vampire queen, herself, Krul Tepes.

"Mika, please, you need to be focused on the mission." Krul scolded but Mika ignored her.

"If you're cold, wear this." He offered the blanket but Yu kindly declined it.

"I think Mitsuba is cold though." He pointed to her in the building. "Why don't you give that to her and get some sleep? We have a long day tomorrow."

Mika looked at Yu's smiling face before sighing and walking off towards Mitsuba. Krul was the only one who stayed behind, looking at Yu for quite sometime.

"What?" Yu asked, wondering if she needed something.

"I don't understand." Krul said. "You were betrayed so many times and lost so much; how can you smile like that?"

Yu looked down at his book he had been writing in to record his most recent events. Even though he was never good at any of that stuff, he figured it'd be best if someone knew about the events that happened if he were to die.

"It's because I still have most of my family with me right now." Yu replied. "Sure I would be sad if they died. Getting over Guren's death was no easy matter but in a sense I can still fight for those who are still alive."

Krul looked at Yu, dumbfounded by his answer and shrugged it off as she went to where Mika was.

Yu slowly took out his pocket watch and checked the time. "0046 hours, I should probably go to sleep now." He quietly told himself as he laid down and shut his eyes.


His dreams soon began to burst throughout his imagination. Thoughts of the war coming to an end, his family still alive and breathing. However, those dreams became nightmares as one-by-one he started to lose a family member to some horrific death. The war then sprang out and he found himself in the midst of a battle with his family.

Kimizuki was struggling with a vampire noble and Shinoa and Mitsuba were held up fighting several other vampires. Yoichi was separated from them, firing his arrows at the vampires from a distance, trying to lend as much support as possible.

"Yu! Go help Kimizuki!" Shinoa ordered as she beheaded a vampire, causing it to turn to dust.

Without thinking too much about it, Yu ran straight for Kimizuki but was stopped by a familiar vampire. The same vampire who cause him pain. Ferid Bathory.

"My my. It seems my precious little lamb has returned to me." He said with his snickering smile.

Unable to control much of his anger, Yu quickly drew his sword and swung. However, the power difference between the too was completely unbalanced. The vampire nobles were known for being strong and Yu knew the only way to at least have some sort of chance was to use one of the strengthening pills.

Quickly reaching into his pocket after breaking away from the vampire, Yu pulled out the small capsule and was about to pop a pill into his mouth before Shinoa smacked it out of his hands. A look of worried had taken over her face as she proceeded to knock the capsule out of his hand too.

"You can't take anymore Yu, you'll die." She said.

Just before he could respond, Yu witness Ferid quickly grab Shinoa and sink his fangs into her neck. Looking around, he noticed the same things happening to his friends. Kimizuki was nearly drained from his blood while Yoichi tried running away from his attackers. Mitsuba was on the ground, bite marks on her neck where she had been bitten.

"No...this can't be happening…" Yu said with a horrified look on his face.

Suddenly, as he turned around, Mika was standing in front of him and bit down hard onto his neck, starting to drink the blood from him.

"Mika...what are you...doing?" He asked before his eyes shut on him.

Yu soon awake in a familiar white space where his demon Asuramaru was. He was quietly standing on top of the sword he possessed, not paying any mind to Yu.

"Asuramaru?" Yu asked but didn't realize the demon was already behind him, piercing his hand through his stomach.

"Too slow." He smiled. "Maybe the angels will save you."

Yu slowly began to feel the blood coming out from his body and the sound of a trumpet being blown. His body soon began to morph, causing him to grow fangs and horns, his eyes turning red.

"No...make it stop!" He begged. "MAKE IT STOP!"


Yu suddenly sat up, his eyes wide open, his breathing heavy. Around him, the area was destroyed, buildings abandoned and the road torn up to make it impossible to drive by car. The sun had slowly poked it's light through the large buildings allowing Yu to see better.

"Yu, are you okay?" Mika asked, worried for him.

Yu turned to look at Mika and slowly took deep breaths to calm himself. "Uh...yeah...I'm fine." He said.

"It was just a dream." Mika told him.

"I-I know." Yu replied as he stood up. "Where is everyone?"

"Still asleep. But it seems the two snipers are awake, look." Mika pointed.

Yu looked to the south where Yoichi and Shinya were stationed and noticed a small flag hanging from the side of a tower. Embroidered on it was the word 'freedom' in capital letters.

"Yu…" Mika tried speaking.

"I know." Yu said. "It's almost time."

So after watching the second season of Owari no Seraph and trying to catch up with the manga I asked myself if I wanted to write a fanfic for it and I decided why not? So I hope you all enjoyed the first chapter I've written and hope you all stay tuned for more. See ya soon!

Oh and if some of you are unaware of what is happening in the middle section it's simply Yu dreaming of events prior to where they are now. Of course I'm not fully caught up with the manga so I can't say for certain what really does happen to anyone so anything that happens is strictly what I believe could happen.
