One of two Windmill and Windmill Oasis' 10th anniversary project that utilizes the E-mote sprite animation system. Yousuke came to the bustling tourist city of Kazashiro to attend the school there. The Western-style houses lining the streets and the townspeople’s attire give the city an exotic charm. To top it off, a ‘witch’ named Ayari will be living with him at the boarding house Oasis, which is owned by his aunt Yuuko. Later, he meets two other ‘witches’ Suzuno and Misumi, and reunites with his older sister-like childhood friend Ririko, who is a ‘knight’. Every day is full of exciting events and before long, they are brought again into a different world. Surely this is the world of love.
