Dei Gratia no Rashinban

How could those girls have survived the abyss? Perhaps different choices might have changed their fate. On August 1, 2033, a deep-sea cruise submarine sinks 700 meters to the ocean floor, claiming 50 lives instantly. The remaining passengers must navigate a path to survival, but an unimaginable threat lurks in the depths. An eternal loop of records and memories unfolds—can the fragments of 'two survivors' save them all? Who lives, who dies—you decide. This is a novel game with no right answers, where despair and mystery collide.
