People from various worlds and across different universes attend Kaginado Academy, a school of which its creation can only be attributed to a miracle. While everyone is trying to lead a normal school life, the clash of bustling personalities causes many of the students to beg questions about their world and the complexes they brought with them. Ryou Fujibayashi feels like her life is dictated by how she is judged by others, expressing her jealousy toward other girls. Yukito Kunisaki constantly finds himself out of place and neglected, continuing to wander around unemployed and penniless. Meanwhile, Ayu Tsukimiya keeps running into the most untimely of situations—all while crashing into her surroundings along the way. Such is life at Kaginado Academy, and all the fourth wall breaking and comedic antics that come with it!

Although it is a miracle that Kaginado Academy remains standing, Yuri Nakamura and her cohorts vow to retaliate against the god that created their universe. Pointing out its many absurdities, she proposes that the academy is actually a stand-in for the afterlife. Yuri's theory makes everyone restless; some begin questioning and even second-guessing their own memories. However, not all agree with the notion, defending the fact that their current existence is a result of their past rather than the interference of an omniscient being. Life at Kaginado Academy continues to be frenetic—despite how much the students want it to be otherwise!

Love is love. Someday, the pain of being in love will be an endearing memory. No matter who the feelings are toward, no matter what form it takes, all love and lifestyles have the same value. An omnibus anime tells the stories of "The wedding of an ex," "a student and a teacher at an all-boys' school," and "childhood friends whose bodies and hearts change with adolescence."
