Mari Yume is a bubbly, fun-loving being who is known as the personification of dreams. After discovering a love of humans but being unable to interact with them, Mari had to find a way to connect with such a fascinating species on a more meaningful level. She found a way to show herself to the humans outside of the dream realm: Becoming a VTuber.

Mari is a professional anime girl who like playing video games, ranting for hours about food, drawing and taking a nice nap now and then. She is obsessed with becoming the best youtuber in the world and represents lucid dreaming, but there is another side that represents the darker images that hide in the night: Pm-chan.

Mari says: "Remember, everything reminds you of something."
