Transmigrated As Satoru's Father (A Jujutsu Kaisen Fanfiction)

Chapter 20

As Seijuro and Mahito locked eyes, the tension between them was palpable. Mahito's grin widened, his stitched face twisting into something even more sinister.

"Well, aren't you an interesting one?" Mahito said, his tone mocking. "That cursed energy of yours... it's chaotic, unstable. You don't even know what you're wielding, do you? A reckless sorcerer playing with forces beyond his understanding—how delicious."

Seijuro kept his gaze steady, his crimson eyes narrowing. "I don't need your approval to do what's right," he replied, his voice calm but with an edge of steel. "Whatever twisted game you're playing here ends now."

Mahito chuckled darkly, his fingers flexing as if he were already imagining molding Seijuro's soul. "Oh, I love it when they act all noble. It makes breaking them so much more satisfying."

Kaori looked between the two men, her breath quickening. The tension was suffocating, and though she didn't fully understand what was happening, she knew she was in danger.

Without warning, Mahito's grin widened further, and he lunged forward, aiming for Kaori. His movements were fluid and unnatural, closing the distance with alarming speed.

Kaori's eyes widened in terror, her body frozen in place.

'Not on my watch!' Seijuro thought as the familiar blue glyph flared beneath him. The world around him seemed to slow, the sounds of the city fading into a distant hum. He didn't notice it; he focused entirely on Kaori's safety.

Seijuro surged forward, his movements precise. He grabbed Kaori by the waist and ducked under Mahito's outstretched arm in a single fluid motion. With a calculated sweep of his leg, he tripped Mahito, sending the cursed spirit sprawling to the ground.

Mahito grunted in surprise as he hit the pavement. "Gah! What..." He blinked, looking around in confusion. Kaori, who had been within his reach, was suddenly gone.

Seijuro didn't hesitate. Cradling Kaori, he dashed down the alleyway, his speed fueled by adrenaline and the strange energy coursing through him. The wind whipped past them as he pushed himself to get as far from Mahito as possible.

Back in the alley, Mahito stood and dusted himself off, his grin faltering momentarily. "What the hell just happened?" he muttered, scanning the area. There was no sign of Kaori or the white-haired sorcerer.

His grin returned, but it was smaller, more calculating. "You're full of surprises, aren't you?" he said to no one. "I'll have to savor this little game next time..." With that, Mahito turned and vanished into the shadows, already plotting his next move.

Meanwhile, Seijuro continued running, Kaori clinging to him tightly, her heart pounding against his chest. Though she didn't understand everything that had just happened, one thing was clear—this man had saved her life.

However, being carried like that only made Kaori more flustered. The adrenaline of the moment was quickly replaced by embarrassment and frustration, especially considering her awful day at work.

"P-Put me down!" Kaori yelled, squirming in his arms.

"Stop wriggling, will you?!" Seijuro retorted, his grip tightening slightly to keep her secure as he ran. "I just saved your—"

Before he could finish his sentence, Kaori's fist slammed into his back.

"Hey! Quit that!" he shouted, but Kaori didn't stop. She doubled down, now pounding on his shoulder.

"Oh, for crying out lou—"

Without warning, Kaori leaned in and bit down hard on Seijuro's shoulder.
