A mage mocked as a "weed-sprouter" becomes indispensable in a monster dungeon.
About
As a member of the Hero's party, Guest is a mage who uses magic to create plants. However, because this was deemed useless in combat, the Hero mocked Guest as a mere "weed-sprouter." One day, Guest becomes separated from the party. Searching for their companions, Guest ends up in a massive dungeon inhabited by monsters. Deep underground, where sunlight and soil are scarce, plants rarely grow. The monsters living there suffer from a severe lack of edible flora, medicinal herbs, ingredients for antidotes, air-purifying plants, and even vines or wood for shelter. To them, greenery is a priceless treasure. When Guest appears before them, capable of creating plants at will, the magic dismissed as useless on the surface becomes a power everyone craves. "...You can grow plants?" Thus begins the strange dungeon life of an abandoned mage and a group of monsters. In truth, Guest has elven ancestry, which is why their plant magic is so potent. The monsters are friendly toward Guest and, while they possess human-like forms, they all retain non-human characteristics.
