The inciting incident occurs when Arisa’s younger sister, Miyabi, the only person she genuinely loves, is murdered in a complex, premeditated crime designed to look like an accident.

This aligns with the cynical tone often found in adult-oriented visual novels. It suggests that true justice is not handed down by the heavens, but must be stolen by those cunning enough to take it.

Arisa investigates the surface level of the Clockwork Syndicate. She uses her 72-hour rewind to gather intelligence, purposefully triggering failures to expose enemy patterns. Each failure ages her — her hair begins to grey, crows feet appear around her eyes. The tension is not "will she win?" but "how many years of her life is she willing to burn for one piece of information?"
