Hatsune-Jima was once well-known for its cherry trees, which would bloom no matter what time of year it was. Two years ago, the island's cherry trees lost this ability and all became ordinary cherry trees that bloom only in the spring. Jun'ichi Asakura is now a graduating senior at Kazami Academy, and is surrounded by many close friends, old and new alike. On a stormy summer day, a mysterious young girl, Aisia, arrives at Jun'ichi's door. She is looking for Sakura's grandmother to study magic, ultimately hoping to bring happiness to everyone. When she discovers that grandmother Yoshino had long since passed away, she joyfully assumes (thanks to his error in judgment) that Jun'ichi is able to teach her. Even though she finally understands that the only magic he's capable of is conjuring Japanese confections, Aisia continues her search for magic on Hatsune-Jima. Amid the chaos of her search, Kazami Academy hires new medical staff. (Source: ANN)

Even so, the presence of this adorable soul will only bring more positivity and happiness to Fushihara-san's life as the two spend more time together.

Far from the city's noise lies Torishirojima—a quaint and peaceful island where time seems to move slowly. Hairi Takahara, a young boy nursing a wounded heart, uses the recent death of his grandmother as a quiet reason to leave the city for a summer retreat to Torishirojima. Upon reaching the island, Hairi finds himself surrounded by a refreshing, laid-back atmosphere, a far cry from the hustle and bustle he is used to. After moving in with his aunt, Kyouko Misaki, he prepares to spend the summer helping her sort through a shed full of artifacts his grandmother collected over the years alongside his cousin, Umi Katou, who is staying with them. While adjusting to the island's slower pace, Hairi decides to spend his free time exploring. He soon meets the cheerful Tsumugi Wenders; the antisocial Shiroha Naruse; the wandering Kamome Kushima; and the sharp-tongued Ao Sorakado. Drawn into their lives and the island's subtle mysteries, Hairi is gradually swept up in a summer filled with fun, nostalgia, and life-changing moments that will stay with him forever.
