Merry Nightmare メリー・ナイトメア

Her design motif is a sheep. The name's origin comes from the song that everyone knows. Merry is a girl from the Dreamworld searching for a door back home. Unlike the other dream demons coming into the human world, she doesn't need a vessel, instead she has a physical human-like body, she is stronger and faster than a normal human even in the real world. Merry can't eat spicy food or drink soda (though she was originally really excited to try cola after Yumeji first explained it to her), but she loves doughnuts above everything and likes video games a lot. She currently works at the Tachibana's restaurant, the STO cafe.
