Mizu Mahou gurai shika Torie ga Nai kedo Gendai Chishiki ga Areba Juubun dayone?

Frim is a five-year-old orphan navigating the brutal streets of a sprawling slum district. Though she appears to be just another destitute child, she carries the memories of a past life in Japan. Her daily existence is defined by relentless violence and injustice, leaving her entirely alone with no one to turn to for protection or guidance. In a world where even hoping for a simple roof over her head feels like an impossible luxury, survival seems like an insurmountable challenge. Despite her dire circumstances, Frim possesses two distinct advantages: a rudimentary magical ability that allows her to produce water, and the wealth of modern knowledge retained from her previous life. While her aquamancy might seem insignificant on its own, the society around her suffers from a severe lack of innovation, particularly regarding ideas to improve basic living and working conditions. By applying her contemporary understanding to creatively expand the uses of her water magic far beyond merely generating drinking water, Frim begins to carve out a place for herself. Through ingenuity and determination, this overlooked orphan gradually makes her presence known, proving that even the simplest abilities can change everything when paired with the right ideas.
