In a port town, there's an adventurer's shop called "The Raging Kelpie's Tail." This unremarkable shop, frequented by worn-out adventurers, is visited by a pure and innocent child. The confused shopkeeper, wary adventurers, surprised clients, and the gradually jaded child; a small ripple expands from a pebble thrown into the water, slowly changing the adventurer's shop. This is the story of a child who becomes an adventurer. "Hee hee! Adventurers are all no-good people!"
