It is me to fill the stomach of my sister

Left to navigate life on their own, a pair of step-siblings must learn to build a home together without any adult guidance. The story centers on Kyouko, a high school student with an energetic and untamed personality. Far from the typical older sister, she harbors a deep passion for professional wrestling and approaches daily life with boisterous enthusiasm. Her younger stepbrother, still in elementary school, stands in stark contrast to her wild nature. He is a remarkably serious and grounded child who often finds himself flustered by Kyouko’s relentless teasing and unpredictable antics. Despite their clashing temperaments and the frequent embarrassment he endures, the two gradually forge a warm and dependable bond. Their shared household becomes a space where they learn to rely entirely on one another. At the heart of their daily routine is a simple yet meaningful tradition: taking turns cooking meals to fill each other's stomachs. Through the quiet rhythm of preparing food and sharing it at the table, these mismatched siblings transform their solitary living situation into a comforting everyday life, discovering that family can be built through patience, humor, and a home-cooked meal.
