Don't worry Rowan, I'm about to put it back on.
1. Tohno Akiha
Oh come on. If you know me at all, you know this vote would be first. Why? Because in a lot of ways, Akiha is really the sort of person I think everyone would wish they have in their life, at some point or another. On the outside, rather bossy and sharp, but she uses this exterior to hide her pains, worries, and woes, and in the end, what she really wants is a very simple thing, yet it's generally denied to her. This, of course, doesn't even get into the problems she's had pushed onto her due to some other people, but in the end Akiha's a pretty simple person, in terms of what she actually wants - whether she gets that or not, is another matter entirely.
There's also the fact I've written a bloody story about her, but that's another tale for another time...
2. Kokutou Azaka
Take a good bit of Akiha, reduce the Ojou-sama quality, and turn up the attitude a fair bit more, and you mostly have Azaka. She's a hell of a hardworking person and she will be the sort of person who will fight tooth and claw for her friends. She's not the sort of type who would let people get hurt willingly, nor will she allow others to just do as they please if she thinks it's wrong. She also lives a more or less daily struggle due to her origin of "Taboo," which forces her to stray from the norms of society, and struggle with such conflicts that arise out of it, such has having a desire for her own brother. All in all, though, someone who may not be super-powerful, but who is very loyal.
3. Tohsaka Rin
An incredibly powerful magus for her time, and yet someone who is very much a self-sufficient woman and mostly raised herself since the age of six or seven. Forced to live two lives, in a way, due to her lineage, she almost never lets anyone get close to her and figure out her true abilities as a magus, because if they found that out it could be dangerous. She is a rare sort of person who tries to act like an Ojou-sama but fails rather miserably at it, being incredibly prone to dumb mistakes and constantly screwing up, but she is a very loyal, stubborn personality, and a very calculating mind, being highly effective in even the hairiest situations when given adequate time to prepare.
4. Yumizuka Satsuki
Sacchin. Everyone loves Sacchin. After Akiha, Sacchin is probably who I like second most out of the characters that actually have somewhat major roles in the plot of Tsukihime. (This may change if Choice #5 becomes a player, but we'll get to her next.) Sacchin is the sort of girl who really got very bad luck, but she's also the kind of person most people would like to have as a friend, someone who would make them feel nice and welcomed, and not being particularly mean or cruel to anybody. Probably the most popular "non-route" heroine (although I'm sure the Illya fans would disagree) so let's hope that the girl gets her route in the Tsukihime remake - and of course, considering all that happens to her, I'd say that she should at least get laid by the person who she wants to screw.
5. Altrouge Brunestud
I'll be honest... Altrouge absolutely intrigues the hell out of me. I have a hell of a lot of theories going on in my head about just who she is, what she stands for, and so on. I think there is a lot of the Black Princess that we really don't know about, hiding under that cold surface and veneer. The one thing I can say about her, is that there is definitely more to her than meets the eye, and of course, like all of Gaia's weapons, she is rather beautiful. The fact that she is half True Ancestor and half Dead Apostle means that her life is probably even more of a struggle than Akiha's - simultaneously having to deal with the fact that she is supposed to be protecting the planet and yet she is also dependent on humans for food, which would make a story with her very, very interesting, wouldn't you say?
6. Ryougi Mana
Probably a surprising choice, but Mana actually reminds me *A LOT* of how I was as a kid. Incredibly intelligent, well beyond her physical age. Well-read and loves to read. "Precocious" would be a good word to describe her. Mana is the sort of person who will not judge you for your appearance, your background, your past... none of that would matter very much to her. What would matter is your character, who you are and what you believe in. Despite this, she's not stupid, either - she'll be able to tell when you're trying to use her, and she'd get quite mad if treated just like a child. Clearly a case of someone having an old soul, a soul they feel is older than their physical body - something I can agree with, as to this day, I feel "mentally" 5-10 years older in terms of how I think of the world, as opposed to those in my age group.
