Doujins and Dragons (2020)

Here in Suzunaan, a great number of books from the Outside World are hidden in its bookshelves, along with books from more... supernatural sources. One such book is a guide to playing a rather peculiar game from the Outside World. As you play, help Reimu and Marisa get over whatever caused them to avoid each other and get the two girlfriends to beat relationship woes and poor, poor fairies.
