Takes place 2 years after the events of Mountain of Faith. The weather is screwed up so it's up to Reimu or the other protagonists to solve the situation. It's a fighting game, so if you're familiar with Immaterial and Missing Power, you should be able to pick this one right up. Though the new spell-deck card system takes a while to get used to, it's pretty fun.
Anyone up for a game? PS: Don't ask me where to find it.
