In the core of a dying world, a single heartbeat can break the silence.

Noria, a girl forgotten by the universe, remains on her deathbed holding onto her dying wish. A mysterious figure, who refers to himself as Null, hears her wish and promises to grant it before she passes on.

While her wish seems like an impossibility, Null takes her into the silence to find the very thing she dreams of finding, while learning along the way that his actions may only cause an even greater despair for himself.
