So, when do we start? (apparently I missed something)
And second, for future reference, might it be fine for you to link the character list in the OP to their respective posts?
Well, it's gotten a lot more interest than I ever expected. My best bet is either tomorrow, or some time this weekend.
As far as linking goes... eh, I guess I might, if I feel like it. I mean, come on, it's :effort:

EDITTED SIGN-UP. ACCEPT ME NAO. I MUST HAVE MIMA.
While I appreciate the background editing, it has been brought to my attention that this type of Youkai is a dragon. You may remember, I personally crossed out dragon on the list Sonae proffered. As such, I would appreciate it if you would post that other profile you mentioned. I apologize for the inconvenience, but this is the best way to handle this in my opinion.
The dispute about Mima has also been brought to my attention. If not for the fact that she edited the post that contained it, you would know that Sonae had already stated her claim to Mima, so I do not hold that against either of you. Now, Sonae has posted her sign-up, which includes Mima. I'm going to assume that your other sign-up also includes Mima. Now, to just give it to Sonae would be unfair, as you did post yours first, as I am asking you to use a different sign-up. On the other hand, to just let you have Mima would be unfair to her, as she does have the proper sign-up, and she did state her claim at an earlier date. As such, I request that either the two of you settle this yourselves (in a civil manner, please) or let me take over. As you are both my friends, I will try to be as objective as possible. Now, of course, if your other sign-up does not include Mima, this is not a problem. Again, I apologize for the inconvenience.
stupid forum, stupid me... I just deleted my character description by accident, gdi 
That's why you save it in a document first :V
Name: Huang Mikan (黄密砍) [Huang being her surname, just letting you non-Asians know! In Asia, last names go first!]
Youkai type: Human-type Youkai(Think Meiling! Yes, I envision her to be the same type of Youkai as Meiling)(Much thanks Tempest!)
Gender: Female
Touhou character: Flandre Scarlet (Uuu~!)
Appearance: Mikan has long, flowing black hair reaching all the way to her chest should it be hanging in front of her face and, speaking of which, her chest size is normal, unlike her counterpart. As for her height, she stands at 160cm, nothing far too spectacular. At the beginning, she starts off in the generic meido maid outfit that can be seen on Sakuya. Later on, as she escapes the Scarlet Devil Mansion, she steals some of Meiling's clothing, fortunately finding an older pair that suits her, although slightly baggy. Along with that set of clothes, she found one of Meiling's hair ribbons, which she promptly used to tie her locks, creating a short little bundle of hair that neatly hangs from her shoulder, or at her back. She looks nothing like Meiling - but still hawt - so DO NOT EVER MIX HER AND MEILING UP, EVER, OR I WILL RIP YOUR HEAD OFF, JAOOOOOO!
Personality: She has a very calm disposition, rarely getting worried or frustrated. However, getting her mad will push her to limits wherein she will solve the problem to the best of her ability, a hyperdrive mode of sorts. So if you get on her bad side, you had better make sure you can fend her off. Note that this can also apply to determination, thereby making her an efficient worker under pressure. Either way, pissing her off is something hard to do since she is calm by nature. Otherwise, she is generally submissive to authority, namely, Flandre, Patchouli, Remilia and Sakuya, but note that Flandre is a special case in that when she does something stupid Mikan knows. She is caring of her charge, Flandre, even though she has not been here too long. Mikan is friendly to everyone she meets, however this is not to be mixed up with naivety. She knows where to draw the line, and maintains it well.
Stats: 12
-Intelligence: 1+3=4
-Danmaku Prowess: 1+2=3
-Strength: 1+2=3
-Agility: 1+4=5
-Stamina: 1+1=2
Background: Wherever she came from, she was found Remilia during one of her walks.
~PROPOSED STORYLINE FROM HERE~
From there on, she was trained to be a maid, to be groomed like Sakuya. However, since she seemed to possess greater intelligence in comparison to the fairy maids, she was chosen to take charge of Flandre. Fortunately, Mikan's calm disposition and motherly instincts to care made her perfect to take care of Flandre, both as a companion and as a maid. It took an incredibly short time for them to become close. A short time later, the Scarlet Devil Mansion received news of the two missing barrier maidens, and that was when Flandre hatched her plan to take a little trip to the world outside the Scarlet Devil Mansion. After all, she was both curious about these "incidents" she had been hearing so much about as well as the world itself. Mikan, not truly knowing the threat that Flandre posed having never been told since it is not the best of ideas to scare away potential, agreed to her plan, only ever worrying about how Remilia would feel. Otherwise, she was convinced that Flandre would be safe, and she would be able to bring her home somehow. In actuality, she should have been worried about whether other people would be safe.
Location: Scarlet Devil Mansion (duh)
Other:
Please don't take the Meiling thing as a joke. Don't mix her up with Meiling, because they don't even look alike and it will get irritating >_>".
But yes, you may feel free to translate Mikan's name in Japanese if your character only sees it on paper somehow. Kurenai Misuzu~!
Uuu!
Accepted! Good to finally have somebody from the SDM.
I'll shoot someone if I don't get Mima.
Name: Sayuri
Youkai type: Spirit
Gender: Female
Touhou character: Mima
Appearance: Short hair, Hitaikakushi. Dress with frilled ribbon. Ghostly tail. Will load image once it's finished
Personality: Fairy-like. Cheerful, Curious, Energetic, Playful, Innocent. She's unaware of what she is, and thus, doesn't act much like one.
Stats:
-Intelligence: 3
-Danmaku Prowess: 5
-Strength: 1
-Agility: 5
-Stamina: 3
Background: She's a newborn. Doesn't have one yet.

Other: Being a Spirit, she has the natural ability of being able to pass through objects. She can also understand her fellow spirits
Putting this on hold until the Mima dispute is settled.
so correct me If I'm wrong but it looks like the plan will go like this.
1. wander around
2. change into youkai
3. meet partner
4. train/ learn
5. find each other
6. ADVENTURE!
sorry I'm in an analyzing mode now...
Eh, not much of step one, step two happens first, and stuff may happen between your step 2 and step 3. Also, 4 and 5 may happen together.
added 2 points to my fairies states since most people had 17 and i had 15
Fair enough. I'll have a look at it.
Well, since the first post is supposed to be about the character waking up for the first time or something like that... I mean it works with youkai that are aspects of things, spirits, newly turned animals... but oni exist as a species, I'd assume that the don't just pop out of sake bottles... the same would go for satori tbh...
I guess these could just be chalked up as freak cases or something, I'm too tired right now to think about it.
Paradox.
Best answer.
^This. That, or um... Eh, I'll figure out a way to make it work. Like make her grow very quickly throughout the RP or something. Or, Hanzo could make a young Oni. It would be more convenient if you went with something else, but don't let that stop you.
