Game Mechanics

The branching system tracks hidden heroine affection points (好感度) across the May through July common route alongside global clear flags saved in system data. Understanding how these two layers interact keeps you from accidentally hitting a Bad End or replaying early chapters unnecessarily.

Affection Thresholds

Every choice in the common route awards affection points to one or more heroines. At the end of the common route in early July, the game checks which heroine meets the minimum threshold (typically +65 or higher) and enters her individual route.

If your choices split affection evenly across multiple heroines so that nobody reaches the threshold, the game exits the common route into a Bad End on your second or later playthrough. Individual routes are largely linear once entered, with occasional choices that only affect scene dialogue or expression differentials.

Route Unlock Gates

Global system data records each cleared ending across saves, unlocking new branches on subsequent runs.

Helper Navigation (おたすけナビ)

Console ports (PS2, PSP) and the 2009 PC backport include an optional toggle in the settings menu called おたすけナビ. When active, a visual indicator highlights which choice increases affection for your current target heroine.

Note that おたすけナビ optimizes for reaching endings cleanly rather than exhausting every expression differential. When aiming for 100% CG completion, still save before optional branches listed on the Missables & CG page.

Common Route Save Anchors

Because early May choices only shift minor dialogue and small affection values, you can keep two master saves on your second playthrough to cover every remaining route cleanly.
