Happy birthday Rowan. (late birthday, I mean. Sorry.
) Where's that Hisui doujin? j/k
1. Ryougi Shiki
She got my attention the moment I saw her for the first time in the first KnK movie. Her kimono+jacket combo is awesome. Her character development is well done(her two personalities, losing one, living on with the other, eventually wanting to live a normal life with Mikiya), and she's cute. What's even cuter about her is that she doesn't try to be attractive. She just has that charisma. She can own your ass for free with her powers to see death like Tohno/Nanaya Shiki can, but she has a very better control over hers. She's also my main in MBAA.
2.Tohsaka Rin
My favorite heroine from F/SN. While Saber and Sakura are also cool, there's something about Rin that gets to me. Mainly, it has to be that she plays hard to get. She gives an appearance of a 'perfect ojou-sama' type, but is actually clumsy. But she makes up for it with her skill in magic. Being the girl you get with in UBW, my favorite route(haven't finished HF yet, but I'm indifferent about that one anyway) also adds onto my reasons she is on my list. Rin IMHO is the one girl I can see Shirou being with work out the most. Also, she's so damn hot, like the magic she uses with her jewels.
3. Yumizuka Satsuki
Sacchin is another favorite mainly because she deserves better luck, but never gets it in Tsukihime. And also almost got a route. She's also fun to play as in MB, especially when one looks in her movelist in-game, her throwdown specials are named "Reach for the Dream" or something to that effect, and I think that's awesome. It really fits with her position in the storyline, a girl who had a thing for Shiki that was never resolved, became a powerful vampire who got killed off by the same guy she loved. Poor Sacchin, I'll always love you, because you deserve it and Shiki never could.
4. Emiya Shirou
Mr. "People die when they are killed", "I am the bone of my sword", and eternal house husband. He is on my list because he's a character I can connect with, mainly in relation to his "I'll put everyone else first before me" mentality. You can't blame him. His family and town he first lived in was burned down to the ground, with him being the only survivor. He gets rescued by Kiritsugu, learns he's a mage, wants to be a mage and save people like he did. But that goes too far, and behold we have Heroic Spirit Emiya, best known simply as Archer.
In F/SN, Archer detests Shirou mainly because Archer is Shirou from the future of Shirou still living with his 'contradiction' of an ideal after the 5th Holy Grail War, an unhappy man who is charged with cleaning up behind others' sins as a Counter Guardian. This goes to an extreme in the Unlimited Blade Works route, when is is revealed that Archer's main aspiration is to kill Shirou in order to not exist, but seeing at this point the two are completely different existances, Archer just wants to beat up the guy who believes in the ideals that made his life a living hell. This is why I like Shirou's character. Another example of a person fighting their own personal demons or in this case, the future version of himself that wants him dead.
I also like the Unlimited Blade Works reality marble he has. Why does everyone forget he has it too? Oh wait, that fucked up anime adaptation, that's why. GAR is mostly said to be invented by Archer, but Shirou is where he came from, so yeah. UBW is the result of Shirou living only as a figurative 'weapon' for others, being able to summon and use projected/traced copies of Noble Phantasms, which relates to him being called a 'hack of a magus'. Again, not his fault. He had a lot of Magic Circuits when he was younger. Kiritsugu just made sure he never activated them, leading to Shirou doing the dangerous makeshift method he used in the Fate route up till Tohsaka helps him out properly in Unlimited Blade Works. And then there's his relationship with Ilya, that asshole Matou Shinji and so on.
So, in short, Shirou is a interesting character with great skills, both on and off the battlefield. But that still won't save him from being the doormat to the rest of the entire cast of F/SN or probably even entire Nasuverse, via Dead Ends or just getting smashed on because he's Shirou. Poor Shirou...
5. Aoko Aozaki
Miss Blue herself, Aoko is on my list because of her personality, her rocking long red hair and her cute phrases when fighting in MB. "Yayayayayaya!!!" "Sugoi Sugoi!" indeed. Can't wait for Witch on the Holy Night so I can learn more about her backstory and why Touko hates her so much. How can she? Aoko is over 9000% independent, sexy, awesome woman.
She should be proud of her sister at least.
6. Hisui AND Kohaku
This was a hard one, so I chose both Hisui and Kohaku like how you can in MB. MINDGAMES, son.
Hisui is a cute, socially awkward and nice maid who's loyal to Shiki, who is fortunately respectful and grateful to her back. I also played as her in MBAC, but having trouble in AA. I wish I can help her learn how to cook...
Kohaku is a troubled, yandere, but oh so enjoyable to be around lady. I'm way behind on Tsukihime(still on Arc route, lol), but she is a very deep and interesting character. Plus, she's boss in half moon in MBAA. Evo 2010 grand finals: suddenly, H-Kohaku mirror matches everywhere!!!
Honorable mention: Caster(Medea), Rider(Medusa, F/SN), Ciel, Lancer(F/SN), Bazette
I also have a thing for Caster because of her backstory involving being cheated on, since then never trusting men until meeting Souchirou, who's very supportive of her. She falls in love with him later on, and so does Souchirou love Caster, but if mess with her the wrong way, prepared to get rocked by top-tier level magic with instant activation! She is also cute to me too, good enough to considered a MILF even, seeing as she wants to be a wife to Souchirou.
Rider is an awesome big sister type who I would love to be a little brother to. Her love for books like I love books and being naturally seductive get to me also.
She's nice if you're nice, even though she's Shinji's servant for a little while, she is a nice lady to Shirou at least.
Ciel is another honorable mention. Likes to eat curry, wears glasses, knows some kungfu, and things already mentioned by others are what keep me looking at danbooru hoping to see more of her.
Lancer for reasons already stated by everyone else. Homie deserved more screentime in F/SN.
Bazette is another awesome cute big sister type I would love to be a little brother too. Plus I like the female hand-to-hand fighter type. A LOT.
This was hard to do, I have a lot of favorites in Nasuverse...
