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)

College student Yuuhi Amamiya's monotonous life is turned upside down with the appearance of Sir Noi Crezant, a talking lizard claiming to be a knight of justice. Crezant elaborates that the world is in peril—threatened by the mage Animus who wishes to annihilate it with his Biscuit Hammer, an enormous structure suspended in Earth's orbit. As the newly appointed Lizard Knight, Yuuhi must fight alongside other Beast Knights to protect the princess and save the planet from destruction. Unimpressed by the prospect of risking his life, Yuuhi continues his day as usual—until a golem created by Animus suddenly confronts him. Yuuhi is instantly overpowered, but his neighbor, Princess Samidare Asahina, luckily rescues him. To his surprise, Samidare's intention starkly differs from Crezant's; instead of saving the world, she aims to destroy it with her own hands. Captivated by her firm ambition, Yuuhi resolves to become stronger and help Samidare realize her goal. As the pair continues to fight against Animus' golems, Yuuhi finds himself gradually gaining an interest in life—but the chains of his past trauma may restrain him from progressing further.
