Zero, the owner of the Soul Clock Shop, has only one percent soul. The rest was taken away from her at birth, leaving her with only a vague memory: the world must remain peaceful and chaos must not occur. For this reason, she guards the old clock that seals the Chaos Demon underground day after day, maintaining the stability on the surface with absolute rules and forgetfulness.
Until the seal cracked, the manager told her: As long as she found six people who had "traded" in exchange for wishes, and guided them to sacrifice all their souls, the world could return to peace. Zero set out with the keys and a carefully crafted set of words.
But what she didn't expect was that when she really walked into the lives of those six people, she saw the anger of the teacher Isa, the gentleness of the demon Lucy, the guilt of the actuary Mephi, the pain of the hunter Cain, the disguise of the girl Aina, and the unwillingness of the fortune teller Ma En - every broken heart is like a mirror, reflecting the erased "person" in her own hole.
A guardian with only one percent of his soul left wanted to trick six victims into sacrificing him, but he learned empathy through getting closer. When the old clock trembled again, Zero's hand holding the key began to tremble - stabilizing the container and finally filling it with temperature.
Intention: Return to the starting point and find resonance with the other half of the soul
