Rozen Rhine Somnus

Rozen Rhine Somnus is a Minor Antagonist in Brambly Boundaries (Monument 14). Rozen Rhine Somnus or Rosie as her peers call her is a student at Brien Academy majoring in practical crafts, art and literature as well as one of the eight prefects. She claims to be undecided on her full career but her time volunteering at the church has steered her towards working with Children.

Sathariel, under the guise of a visiting superintendent ask Rosie to pursue and subdue the Protagonists as well as Himawari Kazami's agents, the Black Knights. Rosie actually succeeds at subduing some of the Protagonists and defeats several Black Knights but after hearing out Himawari Kazami, she's swayed against Sathariel, letting the Protagonists go free and quasi-siding with the Black Knights against what she considers to be an "evil organization".

Appearance
Rosie is a tall girl who wears conservative, almost old fashioned dresses as well as her own version of the Prefect uniform, giving it a more, austere, almost militaristic look whilst extending the skirt down to the ankles. Rosie has short blonde hair kept out of her face by a hairband, blue eyes and a usually disgusted or bored look on her face.

Rosie rarely ever smiles unless she's around children or people she consider to be "truly good" or "truly innocent".

Personality
Rosie sees herself as being better than others but strangely translates this to having to use her time to help the less fortunate through charity work or voluntary social work outside of class. She dislikes other people of her own age and sees herself as more intelligent and worthwhile than her peers.

Rosie has a few friends but has little time for them, seeing no issue in being rude to them or curt with them. She states that her time is both valuable and not something she can spare to people who bore her. Despite this, Rosie tends to be polite and kind-hearted, standing up to things she sees as evil or wrong regardless of what danger it puts herself in, especially in cases wherein she's protecting those younger than her.

Miracle Worker
Miracle Worker has some modicum of personality to it leaving it up to speculation if it's a naturally occurring contract or a more traditionally formed one. The mystery is reinforced by Miracle Worker being one of the stronger Contracts found in Brambly Boundaries, able to singlehandedly defeat many other characters.

Miracle Worker takes the appearance of a very tall humanoid with a deer skull for a head and a long flowing cloak made of black feathers. Miracle Worker has twisted antlers protruding from its head as well as milky white eyes that glow dimly in the dark. Miracle Worker has arms with tridactyl clawed hands that resemble blackened bone or whittled, dark wood as well as legs of a similar description and a ribcage holding some black dripping liquid, all of which are shown rarely when Miracle Worker moves in a way that pushes its cloak out of the way.

Rosie can send Miracle Worker into the minds of other people to destroy them mentally.

Miracle Worker, once inside a person that Rosie has seen within 24 hours, begins to infest its target with disturbing and dark mental imagery. Sometimes it manifests as shadows out the corner of the person's vision and sometimes, it can be as awful as forcing them to vividly re-live a childhood trauma or even a newly conjured nightmare. In this sense, Miracle Worker, through hallucinations can blind and deafen a person.

Miracle Workers hallucinations vary and are impossible to get rid of so long as it's within a target, the biggest limitation to Miracle Worker is that it can only enter the mind of one target at a time. Once Miracle Worker has invaded a person's mind, it cannot do so again for another 48 hours.

However, Miracle Worker, unlike many other Contracts can physically fight. Miracle Worker can take a great deal of physical trauma that seems to not affect Rosie as well as dish out a great amount of physical damage with its claws and jaws. Miracle Worker has been seen ripping through steel girders and managed to dismember a Sathariel Mercenary Assassin sent to dispatch Rosie if she ever betrayed them. When Miracle Worker is physically defending Rosie, it cannot also be using its mind torment ability. Miracle Worker, outside of a target's mind can conjure minor illusions of mist and odd shapes within a 30 metre vicinity but nothing as vivid as what its normal ability conjures.

Corrin Blake
Corrin Blake encounters Rosie in Chapter 4 when Sathariel has conscripted her to their side. He quickly discovers Rosie's affiliations but succumbs to Miracle Worker's ability, conjuring nightmarish exaggerations of his Father's conviction. Due to his loner attitude and lack of combat ability he's quickly subdued and handcuffed by Rosie who comments remorse that she has to do this to him, owing her pity to his young age.

She leaves him a candy bar which he sarcastically thanks her for when she returns to release him. Upon release they agree that they don't intend to be friends but she does express that she is truly sorry for whatever Miracle Worker conjured up. Corrin, a usually paranoid and untrusting boy, believes her.

Lina Lagenmorph
Lina portrays a flirtatious relationship with Rosie which is unreciprocated. She claims to enjoy aspects of her that aren't as perverted as her normal comments such as her height, cold demeanour and doll-like appearance (owing to her strange choice of clothing). Rosie treats Lina like most other people, with disgust and disinterest, only Lina is not put off by this.

Lina is the last to be defeated by Rosie before Himawari changed her mind, but as a form of teasing or genuine belief, Lina constantly asserts that Rosie never used Miracle Worker's ability on her because she went sweet on her. She usually pairs this with reminding her that she never used Uno Song, which is true but only due to Lina lacking material to forfeit at the time to activate it.

When working together, Lina expresses a degree of respect and admiration to Rosie, getting visibly angry and more violent when Sathariel mercenaries target her. Rosie dismisses Lina's advances as teasing but the two can be seen spending time together in later chapters outside of work.
