Story
In a world where dark lands filled with monsters, there was a peculiar phenomenon: "mapmaking" alone proved to be the effective means to purify the darkness and pioneer new lands for humanity. One day, a young pioneer named Zaba encounters a beastkin girl named Rita in a cave within the Uncharted Territory. Guided by Rita's exceptional ability to instantly survey and create maps with her keen ears, as well as her strong determination despite being a slave, Zaba proposes joining her on an expedition.
