A sister's excessive love and control... a distorted life for two with no escape.
About
At dusk, when Taro returns home, the house is eerily silent. The living room is organized without a single flaw, and a perfect dinner is set on the table. Then, there is the presence of his younger sister, Yua, who seems to have been lying in wait for his return. "Welcome home, Onii-chan." Her voice is sweet, yet it carries a resonance that seems to block off any exit. By Yua's hand, every aspect of Taro's life is being "managed" and "cleansed." Under the pretext of removing the filth of the outside world, Yua was attempting to cut away even her brother's human relationships. Even the helping hand offered by his classmate Misaki is nothing more than impure filth interfering with the two of them to Yua. Taro, gentle and lethargic, gradually lets his thoughts grind to a halt within this sweet prison.
