University sophomore Miwako Sumida has hanged herself, leaving those closest to her reeling. In the months before her suicide, she was hiding away in a remote mountainside village, but what, or whom, was she running from?

To Ryusei, a fellow student at Waseda; Chie, Miwako's best friend; and Fumi, Ryusei's older sister, Miwako was more than the blunt, no-nonsense person she projected to the world. Heartbroken, Ryusei begs Chie to take him to the village where Miwako spent her final days. While he is away, Fumi receives an unexpected guest at their shared apartment in Tokyo, increasingly fearful that Miwako's death may ruin what is left of her brother's life. Expanding on the beautifully crafted world of Rainbirds, Clarissa Goenawan gradually pierces through a young woman's careful façade, unmasking her most painful secrets.
