Mai-chan no Onee-san Shiiku Gohan

Mai is an ordinary fifth-grader living a quiet life in the countryside, but her daily routine takes an unexpected turn when she discovers a stunning, blonde-haired high school girl collapsed from starvation right outside her rural home. Despite her older appearance and evident maturity, this mysterious new neighbor proves to be entirely incapable of looking after herself, lacking even the most basic skills needed to cook a meal or manage her own well-being. Faced with this helpless older girl, Mai decides to step up and take full responsibility for her care. The young student dedicates herself to preparing meals and tending to her neighbor's every need, essentially reversing their expected roles. As Mai nurtures the beautiful but clueless teenager back to health, their unconventional dynamic begins to blur the lines between a devoted mother caring for a child and someone affectionately raising a helpless pet. What unfolds is a heartwarming and comedic exploration of an unlikely bond, driven by Mai’s surprising determination to keep her fragile new companion fed, safe, and properly looked after.
