Six-year-old Nola grew up in the reclusive Ashes Abbey under a mysterious mentor. Born with zero magic, she nonetheless possesses Titan-level monstrous strength that can crush stars bare-handed. One day, her mentor claims he's "out of battery" and about to fall into a deep sleep, ordering Nola to go down the mountain and find her five adoptive siblings who left home centuries ago. Because her mentor adheres to the "Vow of Poverty," the naive Nola firmly believes that those five siblings, who haven't been home for hundreds of years, must be doing terribly out there — so broke they can't even afford shoes! And so, clutching a mere twelve rusty copper coins, a bag of "mythic-grade life potions" she mistakes for strawberry-flavored candy beans, and a scrap-iron greatsword taller than herself, little Nola sets out on a journey to "support the whole family." She smashes her sword through the grand hall of the Holy Light Church, forcing out the realm's number-one righteous figure — eldest brother Arthur. She rides a magic dragon and kicks open the gates of hell, feeding candy beans to the brutal Demon King — second brother Lucian — worried he'll starve to death. When Nola, holding a crumpled note, finally assembles the five top overlords of the entire continent, she puffs up in anger and points at their mountains of gold and thrones, delivering her soul-searching question: "What happened to 'the whole family will beg together'? Who exactly is the poor one here?!" And so begins the hilarious, high-octane tale of a six-year-old delivering a dimensional strike to a medieval continent, with five max-level big shots trailing behind her in frantic protection — and fighting over their little sister!
