Sister and Brother

Anna Kazushima is a responsible adult woman, though she does have a slight tendency toward workaholism. Yet despite her maturity, she cannot seem to shake certain childish habits—insisting her younger brother eats his vegetables, trying to wash his back for him, and even sharing the same futon to sleep. But perhaps her overbearing affection is understandable; he is the only family she has left. Her brother, Aito Kazushima, finds himself deeply perplexed by this new living arrangement. His overbearing sister leaves him no privacy to relieve the natural tensions of adolescence—a task most teenage boys without girlfriends and with ample pornography would typically handle on their own. Unfortunately for Aito, his brother-obsessed sister is all too perceptive of his needs. The collection also explores the story behind the Shiina twins, revealing why they harbor such deep resentment toward teachers. Through the kindness and loving support of those around them, the twins slowly overcome their painful memories. Their outright opposition to educators once cast them as temporary antagonists in the story "Okujou no Fuukei."
