I own nothing but the story idea! Thank you and good day.
Prologue: The roar of the lion.
Thunder rocked the ground as a small army advanced through the pounding rain. Among the samurai clad in the armor of the Oda clan was a dark figure. A man with a little hair for a mustache in rounded armor was among them his eyes piercing deep into the darkness of the clouds. Hoof-beats sounded a call to arms as his army continued marching the rain dropping onto his face which nearly blinded him.
A lone warrior walked the opposite direction an umbrella over his head to stop the coming rain. A long katana with golden trim on the hilt and sheathe glittered in the rain as he walked unaware of the coming army. The hoof-beats finally signaled him as he looked up the army racing past him. The warrior whose name was Mitsuhide Akechi looked to the left catching the attention of the commander of the army who locked eyes for a mere moment before he continued on heading towards the cliff ledge. Mitsuhide tossed the umbrella and sighed as he turned around. "That small of an army used to combat such a large force?" he asked himself scoffing.
"This Nobunaga is a fool."
Nobunaga slowly unsheathed Demon Regalia pointing it down the cliff ledge. His army immediately charged down their weapons brandished and ready to massacre. Nobunaga himself lead the chair the sword waving wildly. Below them the Imagawa army continued their own march unaware of the demon king coming for them. A commander stopped turning to look at the puddle below him. Vibrations rocked it and caused its image to distort turning the lightning into a sword like image. The commander scowled as he looked up only to gasp in fear of what he saw.
Nobunaga laughed loudly as he leapt off of his horse the thunder cracking as he activated his alternate form. His fingernails elongated into talons and shoulder blade's extended into large black feathered wings. His eyes glowed red with energy as he charged into the midst of the army. His arms moved wildly cleaving the armor and flesh from the bodies of the Imagawa army soldier's who dared to stand against him. "No he is not a fool…no he is indeed smart." Mitsuhide said as he watched the carnage.
"This Nobunaga is the Demon King. Perhaps…he is the one that will unify this land."
Yoshimoto lay curled in his carriage looking around him and out the windows. Soldiers with spears watched him from all sides slowly advancing on him. Ravens were seated atop the carriage awaiting the coming death. Nobunaga smiled as he lowered his hand watching the spear-men impaling the carriage and the rider inside. The ravens flew away from fear as the demon king laughed loudly.
2 months later
Nobunaga removed his hand from his face as he stood up grabbing Demon Regalia from Ranmaru. He looked around at the officers gathered before him the look of blank emotion on his face. "I have had a vision. Our victory at Okehazama introduced the world to the name of Nobunaga however this world was built with might it runs on might and only the greatest might shall be able to overcome it. That is what the land desires and that is what I desire as well." He told them looking at his wife No who smiled at him seductively.
"Mitsuhide!" he shouted which was met with his officer standing.
"Katsuie, Hideyoshi, Tadakatsu, Ieyasu!" he shouted as each of the officers stood up. He turned away from the group and looked out at the new army. The Takeda army.
"We will punish ridicule and destroy the Takeda where they stand!"
