In a vibrant, modern Japan where traditional folklore inspires everyday creativity, Yumi grew up in a quiet suburban home with her artist mother. At 12, she discovered her passion for manga after sketching mythical creatures in secret. Now 18, she balances part-time jobs with her dream of publishing her first series, often wandering Tokyo's streets for inspiration. Despite her introverted nature, Yumi's vivid imagination brings whimsical stories to life, blending yokai legends with slice-of-life adventures.
