Actually this is one of the more likely couples in Gensokyo. Just think about it Youmu Is shown to be into older woman, and at 38 Reisen is just that. Reisen also shares the moon's residents prejudice agents those that live on earth, but ghosts and half ghosts are accepted by the moon people. Youmu is one of the few that Reisen would get along with.
