[b]Age[/b]: 3
[b]Affiliation[/b]: N/A
[b]Background[/b]: Plain's past is is a short one. When she awoke for the first time, she was lying in bed in a small, London apartment, with no recollection of anything having existed before that. Her mind was a haze, and it took her some time to become acclimated to her body and thoughts, but eventually she managed to muster the strength to sit up.

What she found upon examining her surroundings was a rather decorated, girlish bedroom, containing several inconsequential things in addition to a single note, placed importantly on the bedside table. The note read, [i]"Wait."[/i], so this is what Plain did.

She waited. And waited. Until finally, one day, something changed in her monotonous, colourless little slice of the world.

Strange markings unlike anything Plain had ever seen appeared on the back of her hand. Instinctively, through the haze of her thoughts, she comprehended their nature and realized that this was the sign that she was waiting for. Excited to finally be doing something besides lying in bed, Plain lifted herself up, gathered her meagre belongings and collected a suitcase she somehow knew was hidden beneath the floorboards of her room.

And then, she set off on a journey. Not knowing what might be in store for her, or even knowing who or what she was, she headed vaguely towards Russia, simply wandering and using what subconscious knowledge she possessed to navigate the previously unexplored outside world.

[b][u]Traits[/u][/b]
[b]Doll Body[/b]
While the truth of Plain's conception is not known, even to her, her body has very clearly been constructed with great care and skillful, meticulous hard work. She appears unassuming, but everything about her being could be said to be a masterpiece of doll-making. She is the embodiment of [i]"Something to be loved by humans"[/i], and while she lacks combat skills, she does possess a strange sort of charm to her that draws the affection of others.

As something that functions outside of traditional human biological limitations, many methods of attack which would work on an ordinary human fail to have any effect on her. She does, however, still possess all of the conventional limitations of a physical form, and she holds no special resilience against physical trauma or sorcery.

Her ordinary Magic Circuits are of exceptionally high quality, however, they are conspicuously few in number. With some difficulty, she should be able to sustain most Servants eligible to be summoned through the Grail System, although she may have some trouble with Servants possessing powerful Noble Phantasms or those of the Berserker class.

[b]Black Grimoire Rose Garden[/b]
The true purpose of the doll called Plain, which takes the form of a terrible, rose-shaped organ located where any ordinary human would have their heart. This organ is a cruel construct, surrounding itself with black thorns which could be called the physical manifestation of the rose's curse. These thorns will grow, incredibly slowly, acclimating themselves to the victim's body and ingraining themselves in their very soul. By the time the thorns have fully attached themselves, it is already physically impossible to remove them, as they have completely entwined themselves with the victim's internal organs to the point where any attempt to remove them will result in fatally wounding oneself. 

The thorns will eventually spread to the victim's entire body, filling every inch of space within their physical form with its black, twisted branches. When the affected party eventually dies, their fading soul which has been completely bound by the rose's thorns will in turn become a part of the rose, strengthening the curse and allowing a new rose to bloom from their corpse. This is how the curse has grown to be as strong as it is today, through countless generations of careful nurturing and constant sacrifice. 

The end result is this.

It is an undoubtedly lethal curse, and the most fatal part of it all has yet to even be said. The true nature of the curse, is its quality of [i]"Growth"[/i]. That is, when the rose is interfered with or perceives there to be a threat to its purpose, it sends a signal of [i]"Growth"[/i] to the rest of the curse. This rapidly accelerates the process in which the curse expands, speeding up what would ordinarily be a task of many years to one that can conclude in less than a few months. Continued interference will, startlingly quickly, complete the curse's incredibly slow growth cycle and kill its victim before one has a chance to remove the incredibly complex and finicky curse in its entirety.

For one to acquire the curse, through a means besides possessing the rose, one must become pricked by one of the rose's thorns. Varying based on the victim's resistance, the curse will begin to manifest somewhere between a few minutes and several days after the initial contact, and destroying the original rose will result in the curse failing to properly manifest in the new victim.

[b]Magecraft[/b]
The knowledge of Magecraft possessed by Plain is surprisingly expansive, suggesting her background to be something beyond an existence of simple companionship. While her combat prowess is non-existent, she is rather skilled in techniques for healing and Bounded Fields, and is also talented in the management of Familiars. Besides this, she simply possesses a skillset that can be dubbed [i]"General Magecraft"[/i], covering the basics of what any Magus should know.

[b]Others[/b]: Excellent waifu material, but not all that useful besides.
