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 blows up anything important but Nendou chases after him. Suddenly, the fire extinguisher exploded when Kusuo sneezed hitting Nendou who then said that he's gonna sneeze now but still fails. It was revealed how he was carrying a plant with pollen. Kusuo then starts running and seeing how Nendou's still chasing him, Kusuo decided to knock him out cold and teleport but he then once again sneezed which destroyed the wall of the school calling out the attention of students. Kusuo, who then thought that pollen would be his downfall saw everyone panic as they cover their eyes from the pollen. He was instead saved by the pollen.
