12-year-old Rilka dreams of becoming a legendary hero, just like the ones in the stories! With her father away on duty as a knight, she lives a peaceful life with her gentle yet clumsy mother. Rilka always thought she had to be the responsible one—until one day, a letter arrives. After reading it, her mother casually announces,"The Demon Lord has revived, so I’m off to defeat him!" Wait… WHAT?! That’s a hero’s job! But to Rilka’s utter shock, her mother simply smiles and says: "It’s fine. I am the Hero, after all." Thus begins a wild, over-the-top fantasy adventure featuring an overpowered yet easygoing mom and her exasperated daughter, who just wanted to be the hero for once! Will Rilka ever live up to her dream, or will her mother’s legend overshadow her forever?!
