The chief maid of Pandæmonium inside the demonic realm of Makai and one of the cloest servants to the Demon Goddess, Shinki. While she may be similar to one 'blade wielding maid', Yumeko makes up for this by having the use of not only blades and knives...but also actual
swords that can be used at her disposal. Her position as head maid is not just because she's close to Shinki, rather, it is due to her being the strongest of the goddess' creations in all of Makai (one could perhaps argue that she was the first), having the skill and strength worthy to be called the chief of servants among the demon goddess. Yumeko herself is rather cold, especially towards outsiders/strangers and only seems to show what little kindness she has to her mistress and her fellow demon kind. Yumeko seems to enjoy combat, and is known to use to assert/prove her dominance over those foolish enough to challenge her directly. Her devotion to being Shinki's best servant, seems to bleed directly into her ability in the fray as she is quite tenacious and somewhat difficult to keep down for very long.
