Stella, a twelve-year-old girl with an adventurous spirit, sets out to explore the mysterious Sayama Forest, a place filled with myths, legends, and untold dangers. Determined to prove herself, she quickly finds that this journey is far beyond what she could have imagined. Instead of finding glory, Stella stumbles upon a hidden civilization of monstrous creatures—some friendly, like a wolf-like creature with a quirky attitude, and others more dangerous than she ever feared. As she tries to survive in this strange new world, she must learn to navigate not only the physical threats of the forest but also the complex relationships with the odd creatures she meets along the way. With danger lurking at every turn and secrets buried deep within Sayama's towering trees, Stella must find a way to make a new life for herself in a world where even the friendliest creatures can be hiding dangerous truths.
