From Harpercollins: Our protagonist, an unnamed junior at a prestigious university in Kyoto, is on the verge of dropping out. After rebelling against the dictatorial jock president of the film club, he and his worst and only friend, the diabolical creep Ozu, are personas non grata on campus. For two years, our protagonist has made all the wrong decisions, and now he's about to make another mistake. He and Ozu are preparing for revenge, a fireworks attack at the film club's welcoming party for new members. Then, a chance encounter with a self-proclaimed god sets the confused and distraught young man on a new course. Destiny will bring him together with Akashi, the blunt but charming sophomore he has a crush on, if he’s brave enough to make a move. Yet our protagonist cannot get beyond his profound disillusionment and the moment is lost. But what if there's a universe where he did join the club of his dreams, ditched Ozu for good, and was confident enough to get the girl? A realm of possibility opens up for our protagonist as time rewinds, and from the four-and-a-half-mat tatami floor of his dorm room, he is plunged into a series of adventures that will take him to four parallel universes. In each universe, he is given the opportunity to start over as a freshman, in search of a rose-colored campus life.

From Harpercollins: During a scorching August in Kyoto, our protagonist and his worst friend, Ozu, are locked in a glaring contest in a four-and-a-half-tatami-mat room. Ozu has spilled Coke on the air conditioner’s remote control, the only AC in Shimogamo Yusuisuiso, their famously shabby sweatbox of an apartment building. Vengeful and despairing, our protagonist discusses countermeasures with his secret crush, the reliably blunt Akashi, when Tamura, a strange young man with a bad haircut, appears. Tamura claims to be a time traveler from 25 years in the future, and shows off the time machine he uses to travel. Our protagonist has a brilliant idea: the sweetest revenge would be to go back one day in time and retrieve the functioning remote control. His simple fix is complicated by Ozu and several others who are also eager to take a ride back in time. But in attempting to alter the past, our protagonist foresees the world's extinction. Even more troublingly, Akashi mentions she’s bringing someone to the upcoming bonfire and it's not him. Only one thing remains certain: it's going to be a very long month. Obliteration? Salvation? Coca-Cola? Castella cake? What does the time machine hold for our (not quite) heroes? It all depends on which one gets there first.
