The premise is a gimmick, but the comedy isn't. Four girls who shouldn't exist in the same school become genuinely funny because the show understands each of them completely, their timing, their vulnerabilities, the specific shape of how they lie. It's the kind of comedy where you laugh at the absurdity and then immediately laugh again because you recognize something true about the character beneath it. The ending collapses under its own weight, but by then these four have already won you over in ways the plot never needed to.
Four second-year junior high students sit next to each other in class, and nobody suspects a thing. Tsukumo runs a secret space program from her bedroom. Akane moves through the world as a masterless ninja, bound by codes nobody else understands. Astra can see and manipulate supernatural phenomena that would terrify ordinary people. And Tomo presents herself to the world in a way that defies simple explanation. The catch is that none of them can afford to let their real lives collide with their school lives. So they lie. Small ones, big ones, lies of omission and lies of commission. They keep their worlds separate, their secrets locked down, their double lives compartmentalized. But sitting in the same classroom every day, they start to notice each other. They begin to understand that the girl next to them isn't quite what she claims to be. And slowly, their carefully maintained facades start to crack. What begins as isolated deceptions becomes something stranger: friendship built on the foundation of knowing exactly who you're lying to, and why.
