Despite there being a few hundred visual novels on Steam, very few focus on gay male relationships. Even fewer take things from a furry perspective. Nekojishi provides both to readers.
In Nekojishi, an everyday college student finds his life changed forever when he suddenly gains the ability to see feline spirits. The three spirits become friends with him, and may potentially move toward romantic relationships.
Nekojishi is surprisingly available as a free to play title on Steam. It can be downloaded right now and runs on Windows, Mac and Linux.
