Obsessed with their rather ordinary classmate Ken Kirio, high school students Aimi Miyoshi and Nami Sometani form a peculiar friendship. Every time the girls hang out, they talk about Kirio and fantasize about interacting with the boy they usually just observe from afar. Aimi and Nami are mostly satisfied with the status quo, but they occasionally cannot help but be jealous of those who get to be near their crush—though this still rarely leads them to approach him directly.

In the online game Planet, there is a powerful team of four players. This team goes by the name The Akabane Family, and its members are a pseudo-family that only exists in the game. Although they aren't aware of it, these four players are actually a broken family in real life. A shut-in older brother. A high-achieving younger brother. A father who is not respected by his own children. A mother who neglects her own household. They do not know the warmth of family. They also don't know that the warmth of their online family is only a passing feeling. And most of all, they don't know they are a real family. Centered on the deeds of the Akabane Family in the online game Planet, the story features battles against monsters, clashes with other guilds, and the machinations surrounding Black Bird, the final objective of the game. The tale takes a major turn as it entangles the real world and this real family. (Source: Netflix, edited)
