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

Chapter 30

Mahito lay sprawled on the warm sand, lazily tracing patterns with his finger while little Dagon snoozed peacefully beside him, soft bubbling sounds escaping the cursed spirit's small form.

"When will Kenjaku come back?" Mahito muttered, glancing toward the distant waves.

"Bwwwp... Bwwwpp!" Dagon replied in his usual bubbly tone, as if dreaming.

-Creak!

The heavy door swung open, revealing Kenjaku stepping inside. His composed demeanor was unchanged, but there was a distinct glint in his eyes.

Mahito tilted his head, one brow raised. "Where were you?"

Kenjaku didn't pause, his voice calm yet brimming with satisfaction. "I was searching for clues about the Prison Realm's location. And suffice to say, my efforts have paid off."

"Prison Realm?" Mahito repeated, curiosity sparking in his voice.

Kenjaku folded his arms. "It's a special-grade cursed object capable of sealing anyone—regardless of their strength."

Mahito's eyes lit up with excitement. "Anyone, huh? That's perfect! Imagine that Kaori girl's look when she sees him locked away."

Kenjaku's lips curved into a faint smile. "Indeed. And I now know where it's located."

"Where is it?" Mahito asked, leaning forward eagerly.

"In South America, deep within the Amazon Rainforest."

Mahito's jaw dropped. "That far? What's it doing over there?"

Kenjaku shrugged. "I can't say for sure, but its location doesn't matter. What matters is that I will retrieve it."

"You'll need more than that to truly stop him," a soft yet sharp voice cut through the air.

Kenjaku, Mahito, and Dagon turned toward the doorway, where a petite woman stood. Her long, tied black hair swayed slightly, framing piercing red eyes. She wore a short pink dress and leaned casually against the doorframe, examining it with an almost childlike curiosity.

"So, this is a Domain Expansion," she murmured, her tone analytical yet laced with intrigue. "Jujutsu sorcery is quite remarkable... different from Reality Marbles."

Kenjaku's eyes narrowed. "Who are you?"

The woman turned her gaze to him, a small, knowing smile on her lips. "Altrouge Brunestud. A pleasure."

Kenjaku's tone sharpened. "How did you get in here?"

Altrouge's smile widened as if amused by the question. "I walked through the door."

Kenjaku's eyes narrowed further. Now that he focused, he could feel the immense energy radiating from her—not cursed energy, but something far greater. It was ancient, boundless, and awe-inspiring. Even Mahito and Dagon had noticed it, their usually flippant expressions now wary.

Mahito, ever irreverent, grinned. "Oh? And what's a pretty little princess like you doing here—"

-Swick!

Mahito's words were cut off as his arm was severed in an instant. The dismembered limb fell to the ground with a dull thud.

"Don't call me little," Altrouge said coldly, her crimson eyes narrowing dangerously.

Mahito raised his remaining hand, a nervous laugh escaping him as his severed arm began regenerating. "Woah, woah, calm down! No need to get all snippy."

Altrouge clicked her tongue and shifted her gaze back to Kenjaku, dismissing Mahito entirely. "I'm here to propose a collaboration."

Kenjaku raised a brow. "A collaboration?"
