The tenth game in the Shrine Maiden series. In Mountain of Faith, Reimu and Marisa have discovered something strange on top of a mountain and are investigating. The point system is based on the principle to always shoot something, and never to let time go without some enemy dying.
Playable characters are Reimu Hakurei and Marisa Kirisame. Both characters have a selection of 2 weapon types.
Laser-Marisa has a well-known bug, where the damage her laser does at Power 3.X is immense. Laser-Marisa is forbidden from all serious high-score lists of this game due to this bug that was never fixed.
