The bustling and raining city of Tokyo was filled with civilians, unaware of the impending battle that was about to take place. Geki Omuguri, the White Oni King, wandered down the street with his cannibal blade, Rezoshi, in hand, his eyes scanning the area for his opponent. Suddenly, a small figure caught his eye. It was Koichi Hirose, standing at only 5'3" in a green school uniform, but there was something in his eyes that told Geki this boy was not to be underestimated. As they faced off against each other, Koichi's Echoes ACT 1 suddenly sent a vibrating slash towards Geki. The Oni King easily dodged it, growling low in his throat as he charged at Koichi with his cannibal blade. Koichi evaded the slashes, using his agility to avoid being hit. He quickly called upon his Echoes ACT 2, creating a sound barrier around him to protect himself from Geki's attacks. Geki was impressed by Koichi's strategy, but he wasn't going to let the boy's defense stand in his way. He began to grow and learn in battle inhumanly, adapting to Koichi's moves and quickly overpowering him with brute force. As tears fell from Koichi's eyes, he called upon Echoes ACT 3 and punched Geki, increasing the Oni King's weight and immobilizing him. Geki was furious, but he didn't have time to react as Koichi used Echoes ACT 2 to release a sonic boom that caused explosive damage and disorientation, disorienting him. Seizing the opportunity, Koichi went in for the kill with his Resonant Slash, Echoes ACT 1 creating a vibrating slash that dealt pain with a resonating echo that was powerful enough to send Geki flying across the battlefield. As the White Oni King lay motionless on the ground, Koichi stood over him, panting heavily. "I had to do what I had to do," he said, wiping sweat from his brow. "I didn't want to hurt you, but I had no choice." Geki opened his eyes and looked up at Koichi, a faint smile playing over his lips. "You proved yourself to be a worthy opponent," he said, his voice low and gruff. "But don't think this is the end. We shall meet again, and next time I won't go down so easily." With that, Geki disappeared into the shadows, leaving Koichi to ponder his next move.
