Sibling Showdown

In the dimly lit training room, Toshinori stood with his arms crossed, facing his younger sister, Izumi. She had come seeking answers, determined to understand how her seemingly quirkless brother had transformed into the formidable force he had become.

Izumi's face was filled with curiosity, but her voice was laced with skepticism. "Toshinori, you have to tell me. How did you, of all people, become so strong?"

Toshinori raised an eyebrow. "You really want to know, Izumi? Or are you just here to mock me again?"

Izumi's expression softened as she sighed. "I admit, I've been cruel to you in the past, but I've changed. I genuinely want to understand."

Toshinori nodded. "Very well, I'll show you."

Without warning, Izumi activated her telekinesis quirk, sending objects hurtling toward Toshinori. But he moved with incredible speed, dodging every projectile effortlessly.

He spoke calmly as he evaded her attacks. "Izumi, becoming strong isn't just about having a quirk. It's about hard work, determination, and never giving up."

Izumi's frustration grew as she tried harder to land a hit on her brother, but his agility was beyond her reach. She realized that he was right—strength wasn't solely determined by the presence of a quirk.

Toshinori finally closed the distance between them, disarming Izumi with a swift move. He looked into her eyes, and they flashed with an eerie, dark green glow. "Think about your past actions, Izumi. I may have been quirkless, but I was never powerless. I'm a hunter not a hero."

Izumi stared back, her fear dissipating as she saw the transformation in her brother. She had underestimated him, but now she understood the depth of his strength.

Toshinori gently patted her shoulder. "It's never too late to change, Izumi. I hope you find your own path to becoming stronger."

As she watched her brother leave the training room, Izumi reflected on her past actions and the newfound respect she had for Toshinori. She was determined to change her ways and perhaps find her own strength, whatever form it might take.

later That Moment

Amidst the quiet of their training area, Toshinori and Yu faced each other. The bond between them as brothers was strong, but today, it was about more than just family; it was about teaching and learning.

Toshinori's voice held encouragement as he spoke. "Alright, Yu, let's see how far you've come. Show me what you've got."

Yu, determined to prove himself to his big brother, nodded with a grin. "Watch closely, big brother."

Their sparring session began, with Toshinori launching a flurry of attacks that Yu deftly dodged. Despite his experience and strength, Toshinori wanted to see how Yu could handle himself.

The clash of their abilities was a sight to behold. Toshinori's precise martial arts combined with Yu's control over wind created a beautiful, dynamic dance. They pushed each other to their limits, showing no signs of holding back.

As the battle intensified, Yu felt a surge of power within him. It was like a switch had been flipped, and suddenly, he moved with an almost supernatural speed and precision. His eyes shimmered with an intense dark green glow.

Toshinori's eyes widened in astonishment. "Yu, is that... Ultra instinct?"

Yu nodded, his movements flowing effortlessly. "Yes, big brother, I can feel it."

Their fight continued, but it was clear that Yu had tapped into a new level of power. Toshinori was proud of his little brother, who had achieved something he himself had worked tirelessly to master.

Finally, they paused, their chests heaving, sweat glistening on their foreheads. Toshinori approached Yu with a warm smile. "You've done it, Yu. You've unlocked Ultra instinct. I couldn't be prouder."

Yu, still catching his breath, returned the smile. "It's all thanks to your training, big brother."

They shared a brotherly moment, a silent acknowledgment of their growth and the unbreakable bond between them. Toshinori ruffled Yu's hair affectionately. "From now on, you're not just my little brother. You're a true hunter, and you've earned my respect."

Yu beamed with pride as he looked up at Toshinori. "Thanks, big brother. With your guidance, there's no limit to what I can achieve."

As they continued their training, the wind whirling around them, Toshinori couldn't help but feel a deep sense of fulfillment. His little brother had come a long way, and together, they would face whatever challenges awaited them, stronger than ever before.
