10 Days with My Bratty Stepsister

About this game

Nanaka is moving in, and the arrangement only lasts ten days. Your apartment is far too small for two people, and the girl who once clung to you now answers every attempt at conversation with a cutting remark. She keeps her distance, guards her privacy, and leaves you guessing what changed. Every exchange in that tight shared space carries weight, and the mood of the household can shift on a single reply. This Completed visual novel from Punkif builds its drama out of close quarters and branching decisions. Each of the ten days presents moments where your response nudges the relationship one way or another, gradually steering a complicated step-sibling story toward different outcomes. The artwork is delivered as 2dcg, and the compressed timeline keeps the pacing urgent — there is always another day arriving, and another chance to work out what sits beneath Nanaka’s prickly exterior. Version 1.0.0 runs on Windows and ships with text in English, Japanese, Korean and Simplified Chinese, paired with full Japanese voice acting. The game is also known by its Japanese name, なまいき義妹とヒミツの10日間, and its visuals are mosaic-censored. Since the storyline is finished from start to finish, players who prefer a self-contained narrative can move through it without waiting on updates. Ten days is not much time. Whether the two of you find common ground or spend the visit trading barbs depends entirely on the choices you make along the way.
