This is the 8th Touhou game. It was released at the Comiket 66 Convention in August 2004. This story's focus is on a rather more insidious evil than past games. Gensokyo's yearly event, the Moonviewing Feast, is only one dawn away, but someone seems to have replaced the moon with a fake that will not grow full. A team of human and phantom set out to remedy this before the night is over—the story says that the team the player selects is the only team heading out to investigate.
Each of the usual playable characters gets a teammate from the non-human side of Gensokyo; in this entry. Reimu Hakurei allies with Yukari Yakumo, Yōkai of the Boundary; Marisa Kirisame with Alice Margatroid, Seven-Colored Puppeteer; and Sakuya brings her mistress, Remilia Scarlet. The new team is half-ghost Youmu Konpaku and full-ghost Yuyuko Saigyouji, end-bosses of Perfect Cherry Blossom. All the other characters (except Remilia) appeared in Perfect Cherry Blossom as well.
