Branching Narrative
The story begins with the protagonist stepping onto campus and immediately facing the split vote between the tradition‑focused Gekka Council and the innovation‑driven Tendo Council. Every dialogue choice contributes to a branching path that determines which council the player ultimately supports.
Because the two councils are dead‑even, the protagonist’s final decision creates distinct endings that reflect the chosen council’s philosophy and any romance routes that develop.

- Consider noting the council alignment of each major decision.
