Long Summary
It's pollen season, and Kuniharu mocks his son, who is not at all affected by allergies, saying one day he finally will be. Kusuo was about to rebuke his father, but suddenly sneezed, causing their chairs to brake. Kusuo then announced that he may have allergies. After finding out about his sneeze-exploding allergy, he was given hay fever medicine to prevent him from exploding anything near him. In school, Kusuo wore a mask hoping to get through the day without any problems, but Nendou Riki appeared and started talking to him. It was almost time for Kusuo to drink his medicine when Riki wanted Kusuo to watch him sneeze. Kusuo wasn't interested at all, but Nendou took away his medicine, forcing Kusuo to watch him attempt to sneeze. Kusuo was able to grab his medicine back, but suddenly he sneezed. This caused his medicine to explode and his mask to fall off and get trampled on. Kusuo decided to just teleport home before he blew up anything important, but Nendou chased after him. Suddenly, the fire extinguisher exploded when Kusuo sneezed. The fire extinguisher hit Nendou, who was still attempting to sneeze. Nendou revealed that he was carrying a plant with pollen to make himself sneeze. Kusuo started running and decided to knock Nendou out cold and teleport, but once again he sneezed. His sneeze destroyed the wall of the school, getting the attention of students. Kusuo, who thought that pollen would finally be his downfall saw everyone panic as they covered their eyes from the pollen. He was able to fix the wall without anyone noticing, so the pollen had saved him.
