Notes

One autumn day, you are suddenly isekai-ed into Gensokyo, a land in Japan where Youkai live inside of the Great Hakurei Barrier.
You are a human with no magical ability, thus making you vulnerable to the youkai. Luckily, the Moriya shrine maiden Sanae Kochiya is willing to help you as instructed by her goddesses.
You journey around Gensokyo, helping Sanae take care of the incidences. (Isn't the Hakurei shrine maiden supposed to do this instead...?)
