The fishers who mend their nets downriver claim Kourai's intense gaze can freeze the mist from the great falls. Before earning any such reputation, they were just another trainee in a green bow uniform, their movements with a katana clean but unremarkable. To prove their resolve, they undertook the Silent Crest Trial: a three-day meditation at the very edge of the city, where the river begins its plunge. But on the second night, a freak frost descended, coating the stone in a treacherous, biting glaze. While others retreated, Kourai remained, embracing the cold as a final lesson in focus. They returned not with frostbite, but with a new stillness. The experience had chipped away everything but their will, earning them the moniker "the Frost-Nipped."
