Six years have passed since “Good Night World,” a story of a collapsed family connected in the cyber world, ended. Another story is about to begin.

The latest game “Planet,” in which avatars can be freely controlled in the metaverse.
Zero, a boy who is neglected at home.

Liz, a young girl who longs to become an adult and steps into the Planet.
And a boy, Kano, who connects Zero and Liz. Having no place to belong in the real world, they immersed themselves in a virtual world that spun a temporary bond and became “dependent” on it.

One day, however, the worst “incident” occurs.
