The sun slowly sank behind the silver clouds, leaving a dark sky brimming with countless stars. Tonight, those stars were no longer just lifeless points of light in the sky. They seemed to whisper to the world beneath, and from that whisper, a power awakened — Twinkle. A stream of ethereal energy, as gentle as mist, yet as powerful as the cosmos itself coming to life. Twinkle is not merely light; it is the soul of the sky, the fire of the universe, casting its glow upon hearts that have yet to understand the wonder it brings.Twinkle is not just a force; it is a lifeblood, a breath. Twinkle is not a phenomenon; it is an ideology. It is light, it is hope, but it can also be darkness, a mystery that humanity has only just begun to sense. Each star is not simply a flicker in the night sky but a heartbeat of the universe, a call from the endless abyss. They do not just illuminate space; they open doors to infinite possibilities within each person, powers that are known as "Twinkle." It connects everything in this world, from distant peaks to the deepest corners of every soul. Those who possess it feel that light, not only from without, but as if it burns brightly within their hearts.But to control Twinkle, to understand its gentle radiance, each person needs a key — a heart that can protect their entire universe. And that key is the Heart Core, a magical fragment that holds sacred beings, the very essence of each individual. The Heart Core is not merely power; it is the reflection of the soul, the fusion of light and darkness, the pains and fears yet to be confronted, and the dreams yet to be awakened. These hearts will grow and change with their owners, and sometimes, they will challenge their owners to prove the value of this connection.Each Heart Core, like the stars in the sky, carries a unique story, a path that only its owner can explore. But this journey is not easy. It is not an adventure of strength or knowledge; it is a journey to confront one's true self, to understand that sometimes, the greatest miracle in life is accepting oneself, even when darkness surrounds.And now, as these children enter the Light Academy, they carry not only the flame of Twinkle and the heart containing their Heart Core, but also anxieties, hopes, and questions for which they have yet to find answers. This is not merely an exam of strength, but a challenge to the deepest aspects of their being — mysteries that can only be unraveled by facing them. It is a journey of self-discovery, to uncover the hidden truths about the source of the power they possess.As the exam begins, so too does the battle of these hearts, not against external forces, but against themselves. And as the competition unfolds, the pieces of fate are rearranged, opening a path with no turning back. Will they overcome the darkness within and let the light of Twinkle and Heart Core guide their next steps? Only by confronting the deepest parts of themselves will they touch the greatness of Twinkle.In this world, there are not only humans but also mythical creatures, invisible forces of power, and secret places hidden in the corners of the universe. The sky is no longer just a place for stars; it holds ancient energies that connect different worlds. Humans live in a society that is evolving, where old values are being replaced and new ideals are emerging.Each student, standing under the starry sky, carries with them unanswered questions, the flames of Twinkle burning bright, though no one knows where that light will lead. Will they find their own strength, or will they remain lost in the mysteries they have yet to understand fully?And beneath that starry, mysterious sky, they will continue down a path with no turning back. A journey not only to discover their power but also to find themselves.
