|Japanese Name||夢乃夕作 Yumeno Yuu|
Yuu (real name Yusa Yumeno), also known as the Sleepwalking Ghost, is one of the original characters of the 2017 mobile game Puella Magi Madoka Magica Side Story: Magia Record. She is an NPC of ambiguous moral alignment, who seeks out and kills all "bad people" whose names appear on her magically updating list.

For unknown reasons, Yuu has lost all the memories of the period prior to the time she became a Magical Girl. She is also completely unable to distinguish the morality of others on her own, relying solely on whether or not someone's name is on her list to judge whether a person is good or bad - if a person's name is written on her list, then they are bad, and if it isn't, then they are good. Her judgement is this manner is thus entirely black and white, to the point that Yuu possesses no compunctions regarding seeking out and murdering the people who do appear on her list, nor of extracting their organs after the fact to sell for money.
Towards those that she has judged as good, Yuu appears relatively affable. She is kind to Nagisa, though claims when asked by her that she would not make a good teacher for other magical girls, on account of her lost memories. She later also claims that she will always be on Nagisa's side, and will help her if there is ever the need.
Yuu is regarded as a relatively powerful magical girl, able to defeat fellow magical girl Inui Itsumi with ease, as well as her witch form, which Nagisa previously fell against. Though her weapon is never officially stated, it is presumably something sharp, as she is known to use it to stab and impale people.
Yuu's magical list constantly updates and populates itself with the names of "bad" people. It is possible this list also assists in locating the individuals whose names it states, but the extent of this, if any, is unknown.
- "Yuu" is simply a nickname based on a shortening of her full name, Yusa Yumeno. It is unknown if she herself remains aware of this any longer, due to her memory loss.
- The characters in her last name mean "dream" (夢) and "belonging to" (乃) respectively.
- The characters in her first name mean "evening" (夕) and "harvest" (作) respectively.
- Along with Pernelle, Yuu is the only magical girl in any Magia Record event to possess a unique "costumed" NPC sprite. From this, it can be seen that her magical girl form possesses a large pointed horn, a stitched (or heavily scarred) mouth and hairline, an extremely large furred collar with a matching choker, similarly furred leg warmers worn over her knees, and two "tails" emerging from the back of her outfit that are decorated with three bows each.
- A similar horn has been seen on Yuna Kureha.
