Luka, the eldest son of a farming family in a frontier village, has the memory of his past life as a Japanese person. With a slight tendency towards daydreaming, Luka uses magic as part of his daily life, playing and enjoying his ordinary days in a world where magic is used conveniently. Luka, who has instilled the habit of bathing in his family, bathes with his young sister every day. To keep his sister still in the bath, he tells her stories from his past life and his own imagination. Initially, he used hand gestures to express characters and objects in the stories, but as he began to use magic, the stories became more intricate and detailed, reflecting the meticulous and delicate nature of Japanese craftsmanship. The magic he uses is so intricate that even a top-notch magician would find it difficult to understand. However, such a person would never come to this remote village.
