### PROLOGUE: The Last Promise
The night air tasted like burned sugar and curse residue.
Satoru Gojo stood on the rooftop of Jujutsu High, watching the sunset bleed orange and purple across Tokyo's skyline. In his arms, wrapped in a cursed blanket that hummed with protective barriers, a baby slept. Seven days old. His daughter.
"You're going to change everything," he whispered, brushing a finger against the soft tuft of white hair on her head. The infant's face scrunched, then relaxed. She didn't wake.
Behind him, the door to the rooftop creaked open.
"You called." Shoko Ieiri's voice was flat with exhaustion, but curiosity bled through. "At midnight. On maternity leave. This better be—" She stopped walking when she saw the bundle in his arms. "Satoru."
"I need you to do something."
"Anything. You know that." She moved closer, peering down at the baby. Even in sleep, the child's presence was unmistakable—a pressure in the air, a stillness that felt like standing at the edge of something vast. "She has it, doesn't she? The Six Eyes."
"Both." Gojo's voice cracked. Actually cracked. Shoko had known him for fifteen years and never heard that sound. "The Six Eyes and the Limitless. Full inheritance. First time in history."
"That's..."
"Impossible. Dangerous. A death sentence." He adjusted the blanket. "Everyone will want her. Curse users. Other clans. Even our own people, if they think they can control her. Or eliminate her before she becomes a threat."
Shoko reached out and touched the baby's cheek. The infant stirred, and for just a moment—a fraction of a second—Shoko felt like something was looking back at her from inside those closed eyes.
"What do you need me to do?"
"I've placed a barrier on her. It'll mask her cursed energy completely. Make her appear as a non-sorcerer." Gojo's jaw tightened. "But barriers break. Cursed techniques get found out. I need... I need someone who can heal her. If something happens. Someone I trust."
"You're not staying."
It wasn't a question. Shoko already knew.
"There's a special-grade curse forming in Sendai. Another in Kyoto. The higher-ups are already whispering about her existence. About what she represents." His arms tightened around the baby. "If I stay near her, I'll lead them right to her. The only way to protect her is to make them believe she never existed."
"Satoru—"
"Her name is Akari." He pressed a kiss to the top of her head. "Akari Gojo. Light. Because she's the only good thing I've ever done."
The silence stretched between them.
"When will you come back?"
"When she's ready." Gojo turned to face his oldest friend, and Shoko saw something she never thought she'd see in his eyes—fear. Genuine, bone-deep fear. "Raise her, Shoko. Not as a sorcerer. Let her be normal. Let her be happy. And when she's old enough, when she starts asking questions..." He reached into his pocket and pulled out a sealed envelope. "Give her this."
"What does it say?"
"Everything she needs to know. And nothing she doesn't."
The baby—Akari—woke then. Her eyes opened for the first time in Shoko's presence, and Shoko's breath caught. Not just because of the impossible blue, the depth that seemed to go on forever. But because those eyes looked directly at Gojo with an awareness no week-old infant should possess.
"Hey, princess." Gojo's voice was barely a whisper. "Be good for Aunt Shoko, okay? Don't give her too much trouble." He laughed, wet and broken. "Actually, give her all the trouble. Be loud. Be stubborn. Be everything they don't want you to be."
Akari's tiny hand reached up and grabbed his finger. The grip was impossibly strong.
For a long moment, father and daughter just looked at each other.
Then Gojo handed her to Shoko, stepped back, and vanished.
The baby didn't cry. She just stared at the space where he'd been, her Six Eyes tracking something no one else could see.
Shoko held her close and walked back inside.
She didn't look back at the rooftop either.
