Synopsis

A dysfunctional family of four (consisting of shut-in gaming addict Taichiro Arima, his overachieving younger brother Asuma, their estranged and disregarded father Kojiro, and their disorganized and neglectful mother Sayaka) all cope with their real-world struggles by playing Planet, a virtual reality MMORPG that involves socializing with other players, forming teams, clashing with other guilds, having adventures, and fighting monsters all under the same end goal of being the first to overpower a final boss monster called the "Black Bird of Happiness". In doing so, the Arimas unknowingly form a simulated happy family unit in a team they call "The Akabane Family" with each other, a far more stable simulated family than their real-world counterparts for as long as they follow their one "family rule": no prying information on each other's offline lives. However, when the game eventually becomes part of the real world, learning each other's true identities could make or break their family bond in both realities as well as determine the fate and survival of themselves and others.
