She sets out to slay a dragon and save the princess, but the princess says she loves the dragon and begs her not to hurt it. Then she goes to a neighboring kingdom to serve as the saintess's bodyguard, charged with rescuing the saintess from a lich, but the saintess holds the lich's hand and says everything is fine. So she goes to the kingdom next door, where she hears there's a mansion haunted by an evil spirit. She goes to kill the ghost, only to be stopped by the young heiress trapped inside... And so on, with one employer after another and countless similar situations. The hero, realizing no one needs her anymore, decides to bow out while she still can, quit, and go home to run a farm... But she never expected...
