Luka, the eldest son of a farming family in a remote village, has memories of his past life as a Japanese person and a slight tendency towards daydreaming. In a world where magic is commonly used, Luka uses magic as part of his daily life, playing with it while living an ordinary life. He taught his family the habit of bathing and now always bathes with his younger sister. To keep his sister entertained, he tells her stories from his past life and stories from his imagination. Initially using hand gestures to represent people and objects, his storytelling evolves with magic, creating intricate and delicate magical expressions. This magic is so unique and refined that even a top-tier magician would find it incomprehensible. But, it's a remote village, so no one like that would ever come here.
