Senju

Soon afterward, the trio made their way back to Hashirama's home. The Senju Compound was vast, with beautifully crafted wooden structures surrounded by nature. Birds chirped from the trees, and the wind carried the scent of fresh earth and flowers. As they walked, Mori glanced around, taking in the peaceful atmosphere.

Upon reaching the entrance, Hashirama eagerly pushed open the door, revealing a warm and inviting living space. Inside, a beautiful middle-aged woman with long, flowing red hair sat on a rocking chair. She was reading softly to a small blonde-haired girl who sat on her lap, listening intently. The moment they stepped in, the woman lifted her gaze, her sharp yet kind eyes locking onto Hashirama.

Madara scoffed at the scene, crossing his arms. "I have to go back to the Uchiha compound now," he muttered. Without waiting for a response, he disappeared in a flicker of movement, leaving only a faint disturbance in the air where he had stood.

Hashirama, unfazed, kicked off his shoes and began removing his armor, his excitement barely contained. He burst into the living room with a loud yell. "MITOOOO! TSUNADEEE! I'M HOME!"

Before the red-haired woman, Mito, could react, he had already scooped up the small blonde girl in his arms, twirling her around as she squealed in delight.

"Grampa!" she giggled, wrapping her tiny arms around his neck.

Mito sighed, setting the book down with a gentle snap. As she stood up, her face softened with amusement before instantly shifting into mock irritation. Without warning, she smacked Hashirama on the back of his head with enough force to make him stumble.

"You're absolutely disgusting! Go shower!" she yelled in his ear, her voice stern yet carrying a hint of playfulness. She then gently grabbed Tsunade and set her down on the couch, smoothing out the child's kimono.

Mori stepped into the room, his lips twitching in amusement as he watched the scene unfold. "Looks like the so-called 'God of Shinobi' doesn't amount to much in front of his wife," he remarked with a smirk.

Hashirama rubbed the back of his head, laughing sheepishly. "Sorry, Mito. I just missed you guys so much!"

Mito huffed, crossing her arms. "Missing us is no excuse for tracking dirt into my house."

Ignoring her reprimand, Hashirama beamed. "I managed to convince Madara to come back, and we made a new friend! Mori here beat both me and Madara with only Taijutsu, or 'Martial Arts' as he calls it!"

Tsunade's eyes widened as she looked up at Mori with disbelief. "But Grampa! You said you were the strongest!" she protested, puffing out her cheeks in defiance.

Mito raised an eyebrow, intrigued. "Both you and Madara?" she mused, her sharp mind already analyzing the implications. "That's certainly interesting…"

Hashirama waved a hand dismissively. "Anyway, Mori, you can stay in the Senju Compound for now. There's an extra room on the left!" He grinned widely before throwing his arms into the air. "And I want to learn some of your so-called Martial Arts too!" Without another word, he dashed off towards the bathroom, the sound of running water following shortly after.

Mito shook her head, turning toward Mori with a small sigh. "I apologize for my husband. He acts like this all the time. I hope you don't mind," she said, offering a polite nod. "My name is Mito Uzumaki," she introduced herself before gesturing for Tsunade to come closer. "And this is Tsunade. She turned four years old a few months ago."

Tsunade scrutinized Mori with bright, curious eyes. "Hey! Grampa said you beat him in a fight! Tell me all about it!" she demanded excitedly, grabbing his arm with her small hands and pulling him toward the couch.

Mori allowed himself to be dragged along like a ragdoll, letting out a chuckle as he settled onto the couch. With Tsunade practically bouncing beside him, he began recounting the fight in detail. Her eyes gleamed with fascination, and every time Hashirama's name was mentioned, she shook Mori's arm eagerly.

"Wow! Are you really stronger than my gramp, brother?" she asked, her excitement bubbling over.

Mori smirked, placing a hand on her head and ruffling her soft blonde hair. "Calling me brother already? Cheeky brat," he teased before pinching and stretching her chubby cheeks.

"Bwecause bwotha is stwong!" she mumbled through her squished cheeks, smiling brightly despite the slight discomfort.

Mori let go with a chuckle, shaking his head at her energy.

Moments later, Hashirama burst back into the room, freshly bathed and grinning from ear to ear. Without giving Mori a chance to react, he grabbed him by the arm and sprinted towards the backyard.

"Grandma Mito! I want to go with them!" Tsunade whined, pouting as she reached for her grandmother.

Mito sighed, picking her up with ease. "Alright, alright," she muttered before vanishing in a blur, chasing after the duo.

Upon reaching a large clearing behind the compound, Mori took a deep breath, appreciating the tranquil surroundings. Towering trees framed the open space, and the grass beneath their feet was soft yet firm, perfect for combat.

Hashirama's excitement was palpable as he practically vibrated with energy. "Oi, kid, teach me your martial arts!" he demanded, his hands already gripping Mori's shoulders as he shook him frantically.

Mori hummed in thought, rubbing his chin. "Alright, but first, let's spar. No jutsu, no chakra, just pure physical strength. I need to get a feel for your current state."

Hashirama immediately released him, his entire body trembling with excitement. His grin stretched wide as he stepped back, shifting into a fighting stance. "Alright! Let's do this!"

The moment the words left his mouth, he disappeared, lunging toward Mori at impressive speed. His fist shot forward, aiming directly for Mori's face.

However, Mori remained unfazed. With a subtle movement, he tilted his head slightly, avoiding the attack by a hair's breadth. In the same motion, he grabbed Hashirama's extended arm and pulled it towards himself further, twisting it behind his back in one fluid motion. Before Hashirama could react, Mori delivered four rapid kicks to his elbow joint in the span of a split second before launching a final kick to his chest.

Hashirama was sent skidding backward, his feet dragging through the dirt.

Just then, Mito and Tsunade arrived, their timing impeccable.

Mito's eyes widened in shock at the display, while Tsunade, still too young to fully comprehend what had happened, blinked in confusion.

In the brief second that Hashirama had attacked once, Mori had countered five times and broken his arm with sheer precision.

Hashirama let out a hearty laugh as he grabbed his broken arm, forcefully rearranging the limb back into place. His body's immense vitality took over, rapidly healing the injury within seconds.

Mori watched, unimpressed. "That healing ability of yours is ridiculous."

Hashirama grinned, shaking his newly mended arm. "One of the perks of being me! But damn, that really hurt!"

Mori sighed, crossing his arms. "Then maybe don't rush in like an idiot next time."

Tsunade, still staring at Mori in awe, suddenly clenched her fists. "Brother! Teach me too!" she demanded.

Mori smirked, glancing at Mito, who merely raised an eyebrow before nodding.

"Fine," Mori said, rolling his shoulders. "after this fight though, your "grampa" is about to get his ass kicked"

And so, with the sun casting long shadows over the clearing, Mori prepared to introduce the Senju clan to a whole new way of fighting.
