During summer vacation, Michina and Yuusuke Hirose visit their distant relatives in a rural area. Despite not having seen each other in years, they quickly bond with their cousins Kouchi and Sayumi Tsujii. The siblings enjoy the scenery, swim in a nearby pool, and have a great time together. However, there is one downside to this otherwise enjoyable trip: Souichi Tsujii, the youngest of three Tsuji children and often seen as an outsider, causes trouble wherever he goes. He loves practicing magic and causing mischief with his powers. Whether it's cursing his family members or bewitching his classmates, Souichi always finds ways to ruin the fun for others. But no matter how much chaos he creates, it always comes back to bite him in the end.
