In the latest game, "Planet", players can freely control their avatars within the metaverse. There's Rei, a boy who was neglected at home. Then there's Liz, a girl who wants to be adults so she got into Planet. And there's Yoshino, a boy who connected Rei and Liz. With no place in the real world, they immerse themselves in the virtual world, weaving a temporary bond and becoming "dependent" on it. However, one day, the worst "incident" occurs.
