"Ahg... not happy," Isao grumbled, dropping to his knees. He watched the guy who attacked his daughter pull out the sword from his arm. Annoyed, Isao saw both his arms were useless. Breathing heavily, he just stared at the blood dripping on the ground.
"I don't like killing regular folks, but it's part of the deal, and my client was clear," Nobu said, wiping his sword on his jacket. He noticed Isao's hateful stare. "Sorry about your daughter; it's just business-"
"Shut up!" Isao snapped, standing up aggressively. He bit into the mercenary's neck, slamming him against walls. Despite tasting blood, he didn't let go until the attacker's sword stabbed his shoulder, forcing him to step back.
"That was unexpected... you surprised me," Nobu growled, stopping the bleeding, walking toward the unconscious victim. "I would have liked to see you in the eyes before this... but we don't all get what we want," he said, raising and lowering the sword, letting blood drops fall.
"…" With blood from the hand that stopped the sword mid-flight, Nobu smiled at his main target: Naruto. The blonde held the sword bare-handed, breaking it and kicking Nobu into a concrete wall.
"Are you the famous Uzumaki Naruto?" The short guy in a suit asked, losing his smile, looking at his useless weapon. Naruto, serious, arranged the old bricklayer's body on a cargo lift.
"Who sent you?" Naruto asked, walking slowly toward Nobu, who smirked mockingly.
"You'll have to get the answer from me," Nobu replied, readying his fighting stance. Naruto moved fast, landing a punch in Nobu's stomach, making him convulse and vomit blood.
"You dared..." Naruto lifted Nobu by his hair, exposing a sinister gaze. "...to attack them." With a short breath, Naruto struck Nobu's face. Nobu caught Naruto's fist, twisted his arm, and kicked his chest.
"Yes…" Nobu took off his jacket, revealing twisted muscles. "This strength is more than I thought! I feel invincible!" he shouted, looking at the serious blonde.
Naruto launched a kick, blocked by Nobu, who disappeared and reappeared, landing a powerful right hand. The punishment continued as Nobu kicked Naruto through beams, making him fall into an elevator shaft.
Naruto avoided being stepped on, throwing a punch at Nobu, who dodged it. Their gazes collided, and immediate blows followed, showcasing their contrasting fighting styles. Nobu showed a slight advantage. "Come on!" he urged, blocking Naruto's punch and hitting him in the torso, making him step back. Nobu somersaulted, delivering a hard kick to Naruto's face. "Show me what the great Uzumaki Naruto can do!" Taking Naruto by his clothes, Nobu slammed him against a concrete wall and threw him up, crossing several roofs to reach the fifth floor.
Happy, Nobu jumped down after tossing his opponent. However, he got annoyed when Uzumaki Naruto just stood there, arms crossed, like nothing happened. Naruto, with a serious look, dusted off his broken jacket, noticing Nobu's slow breathing.
"You got my strength and speed. Is that how your power works?" Naruto asked, cracking his neck. Nobu just smiled arrogantly.
"You're smart. Since you know, no point hiding it. I can touch people to get their strength and speed, adding it to mine for an advantage," Nobu explained, taking a fighting stance, facing Naruto who stayed calm.
In silence, Naruto flexed his legs and made fists, an invisible wind covering him as his muscles slightly increased. "Let's see if you can keep up with me," he said, disappearing and reappearing in front of Nobu, hitting him hard. Surprisingly, Nobu returned the blow with equal force.
"You still have hidden strength, huh?" Nobu's muscles grotesquely grew again, exciting him. He attacked Naruto with several dodged blows. After a careless kick, Naruto stepped back, only to be grabbed by the neck and slammed against a wall.
Steam covered Naruto as he held Nobu against the wall, watching his opponent's muscles keep growing. "Third door... open," Naruto whispered, seeing Nobu's body grotesquely expand, muscles tearing and blood flowing.
"Ahhhhhhhhh!" Nobu endured pain as his body was destroyed, bones crushed, and skin torn, blood splattering like in a horror movie.
Sighing heavily, Naruto closed the doors he had opened, realizing the mercenary's body couldn't handle years of hard training. Despite being battered, Nobu was still conscious. "Tell me... Who sent you?" Naruto asked seriously, tightening his grip.
Nobu smirked, "You knew this would happen... no one does what you do without making powerful enemies who want your head. Now, everyone you know will suffer. This is just the beginning." Naruto delivered a hard blow, almost breaking Nobu's jaw.
"Tell me a name!" Losing patience, Naruto hit Nobu relentlessly, disfiguring his face and staining Naruto's hand with blood. Lifting the mercenary from the ground, Naruto smashed him against a beam. "Tell me a name or death will be the least of your problems!" he shouted furiously, not letting the attack on Isao and his daughter go unanswered.
"Hahaha," Nobu laughed with pain, pointing at his chest. Naruto saw a blinking red protuberance, the size of a golf ball.
"Tell me a damn name!" Ignoring the outbreak, Naruto smashed Nobu's head against the metal beam, covering it in blood. The mercenary closed his eyes, his pulse slowing until it stopped completely.
Opening his mouth, Nobu whispered unheard words, forcing Naruto to crouch down. With a dark smile, Nobu whispered, "All for One." The protuberance on his chest lit up in red, causing an explosion that erased the construction site's base, startling nearby civilians and professional heroes who had just arrived.
