Aspiring alchemist Sylvia has successfully completed the road maintenance. When she goes to the town's adventurer guild to pay her respects, she meets the guild master Eileen. Sylvia gets along well with Eileen, who regards Sylvia's mother as a benefactor, but then bad news arrives. 'Emergency! A collapse accident has occurred at the western mine!' Sylvia heads out with Eileen to rescue people. It is a dangerous place infested with monsters. The person needing rescue was also trembling in fear. Sylvia uses her body to give him courage. Although she is thrown off balance by the way he holds her while still frightened, the situation is somehow brought under control. Just when she thinks that is over, Eileen starts acting strangely... In order to repair the tunnel blocked by the collapse accident, Sylvia takes monster semen into her body and activates her 'alchemy' on her very first quest. Huh? Guild master Eileen (a married woman) is also breathing heavily, is she okay?
