Discover a coming-of-age mystery on Seichou Island, where students navigate shifting identities, forbidden bonds, and a campus hiding secrets as deep as their transformations. Choose your path in this expansive visual novel blending romance, discovery, and the science of growth.
Worldbuilding & Premise
1. Isolated Setting: Located between Hokkaido and Sakhalin, Seichou Island’s mist-shrouded campus isolates students undergoing unpredictable physical mutations—from abnormal height spikes to surreal organ adaptations. The island itself is a character, with hidden labs and cryptic legends.
2. Moral Dilemmas: Students must balance academic survival with ethical choices—sharing resources, confronting societal stigma, or exploiting their powers to uncover the island’s origins.
3. Body-Centric Plot Twists: Each transformation carries consequences: Some gain superhuman traits, others face societal rejection, and a few awaken dangerous abilities tied to the island’s forgotten experiments.
Characters & Relationships
1. Diverse Cast: Over 20 characters, each embodying a unique “growth fetish” trope (e.g., a shy athlete with hyper-muscular mutations, a librarian with elongated limbs, a stoic student with translucent skin revealing internal organs).
2. Romance Mechanics: Build trust through intimate moments that adapt to your choices—bonding over shared fears, confessing insecurities, or experimenting with new abilities together. Multiple endings hinge on compatibility and secrecy.
3. Social Dynamics: Form alliances or rivalries via mini-games: Debate ethics in philosophy class, compete in mutation-based sports, or hack into restricted archives to sabotage or support peers.
Gameplay & Narrative Depth
1. Branching Storylines: Decisions impact both personal relationships and the campus’s fragile stability. Ignoring a student’s plea might trigger a violent mutation outbreak—or reveal a hidden ally.
2. Invisible Progression: Track character growth via unique metrics: A shy protagonist’s confidence rise unlocks dialogue options, while a rival’s jealousy escalates if you ignore their advances.
3. Mystery Layers: Solve environmental puzzles to map the island’s history—decoding journal entries, analyzing mutation patterns, or confronting eerie phenomena like “growth storms” that accelerate bodily changes.
