Shinigami was first established for PSP in July 2011, in Japan, followed by PS Vita in July 2019. Here is a synopsis of the game, via VNDB: Toono Sayo is a beautiful girl who lives together with her older brother, Touya, who is a poet. Her older brother tells him about his next story: Shinigami to Shoujo. He explains what it will be about a lonely man and a girl, and his quest for the most beautiful word. One day, when Sayo looked up at the clock tower for a long time that went on as a dispersion by someone wearing strange white clothes. When she asked him about who he is and why he wears such horrible clothes, he told him that he does not remember his identity and that only he knows he’s a shinigami. Sayo suggests that if he don’t know his name, shell give him one and named him Ao (blue) based on how similar the mans eyes are to the sky color. Thanks, @ptc_44iroiro.
