Retasu

Retasu did not come to Waterfall City for the fishing. They stood near the pale stone temple, where the river rushed over its foundations, but their gaze was fixed on the sky, tracking something unseen. Before meeting Aoi, Retasu’s world was bound by parchment maps and well-worn trails. They had charted every peak and valley, believing there were no frontiers left. Then Aoi arrived with schematics for places that didn't exist yet, timelines branching like river deltas. Suddenly, the entire world felt too small. The future became the last uncharted continent. Now they drift together, Aoi with their impossible technology and Retasu with the quiet authority of one who knows how to survive in any wilderness—even one made of pure potential.
