In the midsummer Kyoto that turned into a flaming hell, the only air conditioner in the student apartment failed. The cause was that the monster's friend Ozu let water enter the remote control last night. How am I going to survive the rest of the heat? Just as I was discussing countermeasures with Akashi, the iceberg beauty whom I had a crush on, a rustic male student appeared in front of us and said that he had traveled through a time machine from the future twenty-five years later. So, a genius idea flashed in my mind - why not use a time machine to go back to yesterday and retrieve the remote control that has not been damaged? Facing Ozu and others who unscrupulously changed the world of yesterday, I had a premonition that the world was about to be destroyed.
