Shinda Hazu no Kanojo ~Kanojo Denai "Nani ka" ni Okasarete~

Shinya Miura, who works in the city, lost his beloved girlfriend, Risa, in an accident two years ago.

One summer day, when Shinya returns home from a Bon vacation,
his friends and Risa's parents, have the illusion that Risa is alive.
As if her death had never happened.
