For A Lifetime (Haikyuu One-shots)

Twilight

Day 5 of IwaOi Week

Prompt: Soulmates & Forbidden Love

--

An angel's wings are their treasure but what's more valuable than that are their soulmates. Angels are known to have their wings turn to gold when they meet their soulmates, and they usually meet them at the age of 118.

The Angels and Demons were about to have a Holy War, and Oikawa was excited because it's his first time joining. He couldn't help but flutter his wings in the air. He's one of the most well-known Angels because of how beautiful he is. His wings were big and white, almost as big as Michaels and almost as white as Gabriel's. So, it was no wonder that Oikawa was chosen to guide a Heaven Host to battle.

"Oikawa, don't be too reckless," Hanamaki warned as they fly through the air. The brunette giggled and held onto his sword hilt.

"I won't be, Makki. Besides, if something happens, you and Mattsun would be there for me, right?" Oikawa asked. Hanamakki shook his head in disappointment but still said, "yeah, of course, we'll be there for you,"

They arrived at the battlefield, a vast grassland without any humans, Holy Wars aren't scheduled, but most of the time, the Angels get to choose where the battles are by luring the demons to them. They knew how bloodthirsty demons are and how willing they are to go anywhere as long as they could wreak havoc, so they decided to use it to their advantage.

"Makki, I'm so excited," Oikawa said as the crazed look in his eyes showed.

Here's the thing, Oikawa wasn't just a pretty face. He was an Angel who was intelligent and eccentric. He finds bliss in creating war strategies for the Archangels and finds joy in sword fights, which are things that average Angels don't enjoy.

"Just don't send us out to die, please," Matsukawa intervened as he stays beside Oikawa. The latter laughed and placed a hand on the former's shoulder.

"Mattsun, since when did I give the Archangels plans that failed?" Oikawa asked in confidence. Matsukawa just rolled his eyes as a sign that he refuses to answer because they both knew it was zero.

"See? Of course, I won't send you to your deaths," Oikawa said confidently as they continue to fly towards their destination.

The sun had already set, and the dark night had blanketed the sky. The stars were nowhere to be found, for they refused to be witnesses of the bloodbath that was about to occur. However, the moon stayed to bear witness to the bloodshed as it provides both sides with the luminescence they needed for the battle.

The demons were slowly arriving, some rising from hell and some soaring through the sky. Inhumane noises had ripped through the tranquility of the night and the Archangels, along with their Heavenly Hosts, held onto their sword hilts in anticipation of what's about to come.

The demons drew near, and the war had begun. Swords were clashing as sword glares light the night with every swing, whiplashes reverberated as agonized screams echo into the night. Blood was shed and fell to the ground like raindrops released by the clouds. But in the midst of the frantic fighting, a certain brunette has a smile on his face as he cuts through demons as if he was cutting chicken meat.

Oikawa's wings flapped in the air, letting him freely maneuver around the sky. He lived in Heaven for the entirety of his 118 years of life. No one could beat him in his territory, and he took pride in it, for with every flap of his wings and swing of his sword, a demon's body would be cut in half and fall on the ground below him.

Oikawa was on a spree when a certain demon blocked his path. He had small horns and sharp canines that could cut through flesh. He had gigantic black wings that resembled a bat's, which were almost as big as Oikawa's, and it annoyed the brunette. But what pissed him off even more, is the fact that he thought that he's the most handsome demon he's ever seen.
