It looks like Anime Central is filled with visual novel news this year. Alongside Sekai Project, MangaGamer also brought some announcements to the yearly event.
One such announcement is that the recently-released The House in Fata Morgana is getting a side story. This visual novel is titled Fata Morgana -A Requiem for Innocence- and actually occurs beforehand. It begins with a young girl whose blood supposedly heals others as she awaits execution.
It is currently unknown what the release window for Fata Morgana -A Requiem for Innocence- is, but hopefully it’ll arrive sooner than The House in Fata Morgana did.
