Rose

Rose is the Magimatic Maid of Diablo.

Personality
Originally a simple emotionless NPC Magimatic Maid, Rose gained sentience when she and the rest of the dungeon were transported to the  other world  that Diablo was summoned to. She is very loyal to her master Diablo, considering his will to be the utmost priority.

She becomes livid when someone refers to her as a tool or doll. In her own words, only her master is allowed to refer to her as such. Disobeying Diablo's standing orders is another quick way to earn her wrath. She also doesn't approve of people criticizing her master's tastes.

Rose seems to have a masochistic side, as she is a bit too eager to get her master to physically punish her for each and every mistake she may or may not have committed. She is cold and insensitive about everything that is not related to Diablo. She has a very erotic side, and seductive, but she is inexperienced as Diablo. Her personality is very Yandere, acting cute and affectionate with Diablo, while being cold, violent and cruel, with all the others. Even when Shera called her a friend, she rejects her, as she has no companions, only a master to serve.

When she introduced collar 《Master and Servant Contract》 to Horn, she claims there is not even a price to pay for power. The price and that if the master dies, the servant will also die. From the point of view of Rose, if her master is dead, she will commit suicide soon afterwards, since it does not make sense to stay alive when Diablo is not there for her to serve, so she does not consider that there is a price to be paid. She has the desire to be just her and Diablo as in the time in Cross Reverie.

A female with long pink hair in twin tails and artificial-looking green eyes. She wears a backless maid outfit with detached sleeves and gloves. Her skin seemed transparent, although her fragile appearance, her body and very resistant, her weight and the sum of a knight in armor mounted on horseback, when equipped with 《Magimatic Sol》 Rose it would weigh 44 tons.

There 《Dimension transcending Apparatus 》was some kind of metal attached to the skin was equipped in order to call out the 《Magimatic Soul》, it wasn’t like it was stuck on like a sticker, but more like it was buried in her skin.
