Hikikomori Sister is not just another run-of-the-mill game; it is a thought-provoking and emotionally charged experience that delves into the life of a young girl named Aya. Aya is a hikikomori, a term used in Japan to describe individuals who withdraw from society, often confining themselves to their rooms for extended periods. The game takes players on a journey through Aya’s life, exploring the complex emotions, challenges, and choices she faces.
