Chapter One: A Moonlit promise

The school grounds of Karasumori were quiet that night, the moon casting its silver glow over the worn stone paths and shadowed trees. Young Yoshimori darted between the shadows, clutching a wooden stick like a sword. He was brave—or so he liked to imagine—as he battled unseen enemies lurking in the darkness.

Little did he know, he was being watched.

The princess of the Kokuboro emerged from the mist as if she had been woven into the very fabric of the night. Her presence was magnetic—impossible to ignore. Silvery hair flowed like water down her back, shimmering faintly under the moonlight, and her lavender eyes held an otherworldly charm that seemed to see through Yoshimori. A delicate smile graced her lips, so subtle yet so captivating, as though she knew a secret about the universe itself. Her robes, embroidered with intricate designs, draped around her with a grace that spoke of royalty, but she carried herself with an ease that felt approachable, even playful.

Yoshimori froze in place. At first, he thought she might be an illusion or some strange ayakashi ready to strike, but her beauty left him spellbound, unable to move or think clearly. She was unlike anything he'd ever seen—not scary or monstrous, but breathtakingly radiant, like a star that had descended to walk the earth.

"Little warrior," she said softly, her voice melodic and soothing. "Do you often fight the night, or is this the first time we've crossed paths?"

Yoshimori blinked, unsure how to respond. "I—I'm not scared of the night! I protect people from it. Are you the night?"

She chuckled lightly, the sound pulling him even further into her orbit. "I am what you make of me. Shall we play, young protector?"

Before he could answer, she turned and darted into the shadows, her silken robes billowing behind her like a phantom's veil. Without thinking, Yoshimori chased her, his wooden stick forgotten. She moved quickly, effortlessly, but just slow enough for him to keep up—a dance meant to draw him closer.

As they played, her laughter rang out like bells in the still night. They chased each other around the school grounds, splashed water at the koi pond, and invented names for the stars above. Yoshimori couldn't help but feel exhilarated. The princess seemed kind, gentle, and oddly familiar, as though they had always been destined to meet.

When the moon hung high overhead, and their game slowed to an end, the princess sat beside Yoshimori beneath the great sakura tree, her beauty even more striking in the pale light. "You're a peculiar boy," she said, her lavender eyes softening. "Most humans fear me. But you—you have courage and innocence. It's rare."

Yoshimori stared at her, still captivated by her every word, her every gesture. "You're not scary. You're…nice," he managed to say, though his cheeks flushed at the compliment.

She smiled again, leaning closer. "Do you know what happens when the moon favors someone?"

He shook his head, entranced. Without another word, she brushed her lips against his cheek—a fleeting, innocent kiss that left his heart pounding. She then took out a necklace from within her robes, the tomoe-shaped jewel glistening faintly.

"This is for you," she said, placing it around his neck. "A promise. Someday, when you're older, you'll understand. You'll be mine."

Before Yoshimori could speak, her figure began to fade, the mist swallowing her whole. The echo of her laughter lingered, as did the warmth of her kiss and the weight of the jewel resting against his chest.


The first rays of sunlight painted the sky as Yoshimori wandered home, still clutching the wooden stick he'd left with hours earlier. He couldn't stop touching the necklace around his neck—the tomoe jewel that glistened faintly with an unearthly light. It felt warm against his skin, like it held a secret only he could understand. His heart swirled with emotions he couldn't yet name—part wonder, part confusion. Who was she, really? And what did she mean when she said he would be hers?

As he approached his home, two figures awaited him. One stood tall, stern, and cloaked in an air of wisdom: Yoshimori's grandfather, Shigemori. The other, Masamori, his older brother, leaned against the gate with a mixture of curiosity and quiet authority. Yoshimori blinked, confused by their unusually serious expressions.

"Where have you been, boy?" Shigemori's voice was sharp, but there was an edge of worry hidden beneath the gruffness. His keen eyes immediately locked on the necklace. "And what is that?"

Masamori stepped closer, his gaze calculating and cool. "That doesn't look ordinary, Yoshimori. Did you encounter an ayakashi?"

Yoshimori's heart skipped. He clutched the necklace tighter, unsure how to explain. "I—I met someone. She wasn't scary. She was nice. We…played."

"Played?" Shigemori's voice hardened, his brows furrowing deeply. "No ayakashi 'plays,' Yoshimori. Their kindness is always a trap. Let me see that necklace."

Yoshimori hesitated but relented, allowing his grandfather to examine the tomoe jewel. Shigemori's expression darkened as he held it, the faint hum of its supernatural energy unmistakable.

"This is no ordinary trinket," Shigemori said gravely. "It's a curse, boy. You've been marked by an ayakashi."

Masamori's eyes narrowed, his tone firm. "Marked? It could be a binding spell or a trap meant to lure us into danger. Ayakashi don't act without purpose."

"No!" Yoshimori's voice cracked as he grabbed the necklace back, clutching it close to his chest. "She wasn't bad! She said it was a promise! I think…she liked me."

Both Shigemori and Masamori exchanged a look of disbelief, their minds unable to comprehend an ayakashi who would act out of affection rather than malice. Shigemori's tone softened slightly, though his concern remained. "You're too young to understand, Yoshimori. Ayakashi live in a world apart from ours. Even if she meant no harm, her actions have consequences. This mark could be dangerous."

"But it doesn't feel dangerous," Yoshimori muttered, his voice barely audible. "It feels…special."

Masamori placed a hand on Yoshimori's shoulder, his voice calm but firm. "Special or not, we need to keep an eye on this. If she marked you, it means she sees you as hers—and that could bring trouble. You're part of the Sumimura family. We must protect you."

Yoshimori nodded reluctantly, unable to shake the strange feeling in his chest. As his grandfather and brother began discussing ways to investigate the necklace's origins, he couldn't help but wonder—had he truly been cursed, or had he been chosen for something greater? The words of the princess echoed in his mind: Someday, you'll understand.


The next night, the moon was bright and full, casting silver beams across the quiet school grounds. Yoshimori sat on the steps of the main building, clutching the tomoe necklace around his neck. His thoughts drifted back to the night before—the playful laughter, the shimmering silver hair, the warmth of her kiss. He still wasn't sure if it had been a dream or something real, but the weight of the jewel against his chest told him otherwise.

"Thinking about me, little warrior?" a familiar, lilting voice broke through his reverie.

He looked up, startled, and there she was—the princess of the Kokuboro, standing in the shadows with a teasing smile on her lips. Her lavender eyes glowed faintly in the moonlight, filled with an amusement only she seemed to understand. Yoshimori grinned and jumped to his feet, the excitement of seeing her again overwhelming his young heart.

"Princess! You're back!" he exclaimed, rushing toward her.

"I told you, I'll come whenever I wish," she said playfully, reaching out to ruffle his hair. "Now, shall we play again?"

Yoshimori nodded eagerly, and once more, the two of them vanished into the night, their laughter echoing through the trees. They ran and hid, tossed stones in the koi pond, and watched the stars, their joy unbroken until the faint sound of footsteps interrupted their games.

"Yoshimori!" Shigemori's sharp voice rang out, cutting through the night like a blade. The old kekkaishi appeared from the shadows, his eyes immediately locking onto the princess.

Shigemori froze for a moment, taking in her ethereal beauty. At first, he thought she might be a wandering human spirit, but then his sharp instincts sensed the unmistakable energy of an ayakashi. His expression hardened, and his voice grew harsh. "Stay away from my grandson, you creature."

Yoshimori stepped in front of the princess, his arms outstretched protectively. "No, Grandpa! She's not bad! She's my friend!"

"Step aside, Yoshimori," Shigemori ordered, his kekkai energy flaring to life around him. "You don't understand what she really is. Ayakashi can't be trusted!"

The princess, calm and composed, stepped forward, her lavender eyes meeting Shigemori's without fear. "You wound me, old man. Do I look like a threat to you?"

"You're an ayakashi," Shigemori growled. "Your kind only brings harm."

The princess sighed, shaking her head. "How narrow-minded. Not all of us are monsters. Some of us…" Her gaze shifted to Yoshimori, softening. "…simply wish to protect what is ours."

Shigemori launched an attack, a glowing kekkai forming in his hands, but the princess was quicker. With a flick of her wrist, she dissolved the barrier effortlessly, the power flowing from her calm and controlled. She stepped closer, her aura radiating authority.

"I am not here to harm Yoshimori," she said coolly. "Quite the opposite. He is mine—my chosen mate. No human, not even a kekkaishi, will take him from me."

Yoshimori's eyes widened, and he turned to look at her in confusion. "Mate?"

The princess smiled at him gently, placing a hand on his head. "One day, you'll understand, little warrior."

Shigemori's frustration boiled over. "You will not bind him to you, creature. I won't allow it."

The princess's voice grew firm, her lavender eyes flashing. "You don't have a choice. I've made my claim, and no human can undo it. Now, sleep, old man. You'll forget this night and everything you've seen."

She raised her hand, and a soft glow surrounded Shigemori. His eyes fluttered shut, and he slumped to the ground, his memory of the night erased in an instant. The princess turned back to Yoshimori, her smile returning.

"There, now no one will get in our way," she said, her tone light and playful once more. "Shall we finish our game?"

Yoshimori hesitated, glancing at his grandfather. "Is he okay?"

"He'll be fine," she reassured him. "He just needs rest. Now, come on." She held out her hand, and Yoshimori took it, his trust in her unwavering.

As the dawn approached, she left him once more, disappearing into the mist with a promise in her eyes. The bond between them grew stronger, though neither fully understood what it meant. For Yoshimori, it was the beginning of something he couldn't yet name—a connection that would shape his future in ways he could never imagine.
