Ruler of Dreams.

"Every time you dream, You've visited Gensokyo. Normally what's happening is that you expel your dream self, which is then taken over by your real self. By being in the Dream World, you're currently an irregularity."

Doremy first appeared as the Stage 3 Boss and then as the Extra stage midboss in Legacy of Lunatic Kingdom. She later appears as a playable character in Antinomy of Common Flowers. She owns a dream journal which is said to record the dreams of everyone who has ever dreamt in their life.
