The fourth game in the series was released on August 14, 1998, at Comiket 54. The peace in Gensokyo (first used in this game's title) is broken when a tremendous energy surges from beneath a mountain lake, causing yōkai to swarm the Hakurei Shrine. Reimu Hakurei and Marisa Kirisame travel to seek out and eliminate the source of the disturbance, battling yōkai along the way. It features six stages, with the game ending after Stage 5 if the player selects Easy difficulty or uses a "continue". A notable new feature is a "graze" counter for near-misses. According to ZUN, 200 to 300 copies of the game were sold.
