Plot
When he was eight, Minoru Utsugi lost his parents and older sister in a traumatic incident. Now sixteen and living with the young woman who adopted him, Minoru grapples with survivor's guilt and post-traumatic stress disorder, making him want to simply disappear not only from his own life, but from everyone's memories as well. He wishes, in other words, for complete isolation and solitude. This wish gets translated into something powerful when small alien orbs fall from space and take up residence inside humans, but not all are as harmless as Minoru's, and he soon finds that maybe he's more attached to people and living than he initially thought.
