Mavi is a half-beast witch operating as a fortune teller in a town near the royal capital, celebrated across the continent as much for her beauty as her gifts. When word reaches her that the legendary medicinal herb MoriMori has been found, she sets out expecting a brief collecting trip. What unfolds instead is an escalating epic involving ancient spirits, the demon lord, a masked clam of unclear allegiance, and an inexplicably important melon. The short journey keeps expanding in directions nobody — least of all Mavi — anticipated.
