"Under the P3 law enacted under the Global People's Federation, citizens are ranked according to the Authorization Seals issued by the world government. As spring arrives, the manga lover Marisugawa Arue, set back by a long-lasting illness, finds herself having to live her life as a "chuusotsu" - a person with no education beyond middle school. The chuusotsu are not in possession of any Seals, and are considered to be failures at life. As such, their Authorized Power level is only 5 - young Arue's future is already looking mighty bleak. "How will I be able to accomplish my goals now..." In order to break free of her grim situation, and reach her true goal in life, Arue applies for a government relief program where she will... Share a room with other chuusotsu!? Her two roommates are overwhelmingly unique: a taciturn girl in a souvenir jacket and a crazy otaku girl. And then the three girls are given group challenges to clear. What makes a wonderful life? Synchronize your minds and philosophize on this proposition. "There's no way incompetents like us can do philosophy..." Their time is limited, and failure means that they will immediately get kicked out of the apartment! Will Arue manage to successfully complete the philosophical challenges and achieve a happy, steady-going life...!? This is a philosophical story of how the three girls considered lame ducks by the society spend their unusual youth in a world where Authorization Seals decide the lives of all people."
