Sonic Trace

The manor is the origin of the heroine’s family, and the root of the secrets of soundprint energy that the Watase clan has guarded for generations.
The city is the long journey of hunting soundprints; the factory is the dangerous hub that can spiral out of control at any moment; while the interior of the manor becomes a temporary space where training and bonds quietly take shape.
These locations are scattered across the map, yet they are woven into a single, resonant world through soundprint ripples, signal fluctuations, and the subtle shifts of weather.
Watase Mei has recruited the strongest soundprint envoys. Each of them commands a different soundprint ability—an anomalous yet living frequency that grows and evolves according to the way spiritual power is used.
The story carries surreal imagery through everyday details, and maps real emotions through fantasy metaphors.
“Sound” becomes the core bond connecting reality and the fantastic. The heroine’s profession is “capturing sound,” and sound itself possesses the inherent fantasy quality of being “intangible yet powerful.”
From fantasy setting, to imagery vessel, to narrative fusion and cross-media presentation, the story unfolds across four interwoven dimensions:
Soundprint Manifestation
When the emotional density of a sound reaches its threshold, it condenses into visible Soundprint Crystals.
Warm-golden soundprints: symbolize warm memories and unspoken love. Like a childhood lullaby, they manifest as feather-shaped crystals entwined with starlight.
Deep-blue soundprints: symbolize regret and unfinished wishes. Like an incomplete fishing song, they appear as ice-prism crystals resting on the riverbed; touching them brings a faint, blurred melody.
Crimson soundprints: symbolize fierce obsession and anger. Like the choked sob of a breakdown, they take the form of burning sparks that scorch the heart of anyone who draws near.
Transparent soundprints: symbolize pure curiosity and vitality. Like the most joyful laughter in the world, they appear as floating bubbles that scatter on the wind; touching them lets one briefly feel a child’s pure delight.
I. Game Type & Mechanics: Pure Immersion Through Minimalist Interaction
As an AVG (Visual Novel) that returns to the essence of storytelling, this game abandons complex systems like character nurturing, combat, or puzzle-solving. The core mechanics are entirely focused on "reading" and "listening." Adopting a purely linear narrative structure, the game ensures players never have to worry about trial-and-error branching or the anxiety of missing a crucial choice.
In terms of interaction, the gameplay relies on fundamental dialogue boxes, click-to-advance progression, and seamless scene transitions, complemented by perfectly timed pauses and narrative breathing room. This minimalist design not only lowers the barrier to entry but also completely frees the player's attention from mechanical "operations," allowing them to fully immerse themselves in a hyper-dimensional fantasy world woven from text, character art, and music.
II. Content Scale: A Spacetime Epic Woven Through 15 Main Chapters
The game features a meticulously crafted narrative of approximately 15 main story chapters. This is not just a guarantee of substantial text volume, but a precise measure of emotional progression. These 15 chapters function like acts in a carefully designed stage play, forming a complete, cohesive, and highly compelling narrative arc.
From the initial bewilderment and exploration of entering the hyper-dimensional world, to gradually uncovering the hidden pasts of the all-female cast, and finally reaching the emotional climax that transcends dimensions, these 15 chapters offer dozens of hours of continuous reading. Players will feel as though they are turning the pages of a captivating fantasy novel, experiencing an unbroken, seamless dream across time and space.
III. Unique Highlights: The Ultimate Fusion of an All-Female Cast and Hyper-Dimensional Fantasy
Delicate Bonds and Diverse Ensemble of an All-Female Cast
The game features a purely all-female character roster, delivering not only an ultimate visual aesthetic but also a unique emotional tension in its narrative. Female characters from different timelines and dimensions will cross paths with you, each carrying their own distinct personalities, obsessions, and untold stories. Free from any outside perspectives, you will be fully immersed in the delicate emotional interweaving, mutual salvation, and fateful bonds between them, experiencing a profoundly pure and romantic journey.
Deep Narrative Driven by Hyper-Dimensional Fantasy
The "hyper-dimensional" concept is far more than a mere gimmick; it is the core driving force deeply integrated into the plot. The laws of different dimensions, lost ancient legacies, and futuristic technological relics all serve as crucial clues propelling the story forward. As the 15 main chapters unfold layer by layer, players will gradually piece together the full picture of this grand worldview through highly evocative, foundational dialogue. Every transition between spacetime scenes is accompanied by a seamless flow of custom-tailored BGM, maximizing the atmospheric immersion of the fantasy setting.
Audiovisual Interweaving as an "Emotion Amplifier"
Since the game relies solely on storyline, music, and basic dialogue, the combination of these three elements is pushed to the absolute limit. The music in this game is never just background noise; it acts as an "emotion amplifier" that perfectly syncs with the emotional ebb and flow of the 15 main chapters. At pivotal turning points in the plot, a perfectly timed melody paired with highly evocative text can instantly break through the player's psychological defenses, delivering a profound emotional resonance that far surpasses what complex gameplay mechanics could achieve.
