Four and a half stacks of time machines

August 12th, the scorching Sakyo-ku of Kyoto. The only air conditioner in "Shimogamo Yusuiso" is not turned on. Bad friend Ozu flooded the remote control last night. While "I" was discussing countermeasures with Akashi, the cold beauty of the film club "Mina", a dull-looking male student Tamura, whom I had never met before, appeared. It is said that he came from the future 25 years later in a time machine. At this moment, "I" suddenly had a flash of inspiration. Use this time machine to go back to yesterday and pick up the remote control before it broke! However, Ozu and the others can change yesterday and rewrite the past as they please. "I", who had a premonition of the crisis of world destruction, hurriedly intervened to stop it, but it was already too late! In the end, can the remote control and daily life return safely? ? And, what is the fate of "me" and Akashi's love - between "yesterday" and "today", the story of using a time machine in a daze while looking at the world begins!
