Game opens to Raine preparing to leave for Mt. Fuji, and a final goodbye to her Mother. This is a cutscene, following Raine from her home to the foot of the mountain, passing her Mother, packing her belongings, and leaving all in between. The gameplay begins from the mountain's rear, outside a decrepit wooden house, home of local outcast Ren, known as "The Stonecutter", though he and Raine will meet in due course. Raine begins her initial climb following some small hesitation, aware of the brutal task ahead. The gameplay from here becomes a wide range of platforming sections, until eventually reaching a calm plateau to rest (initial checkpoint). Upon resting, Raine overhears a small rustle within a nearby cave. It is here where Raine and Sora first meet.
