So, first of all, NO SPOILERS WILL BE SPOILERED, ALL OF THEM MAY BE SPOILED
And I am shocked, I say, shocked.
Fate Zero was a full-scale war between consenting, informed adults. A great deal of effort has been spent in acquiring intelligence on the opposing factions. Most participants are experienced fighters, have a reason why they desperately need to win, or otherwise give off the feeling that they know what they're doing. Even Weaver is college-aged, and knows what he's getting into. The big exception is the Ryunosuke/Gilles De Rays pair, who are the deadliest joke characters ever fictioned since The Joker.
However, Tohsaka Rin seems to have gotten into this war mostly by accident. That's the first surprise.
The second surprise is that the story is told from her perspective. In fact, given the way the game opens, one would be forgiven for thinking it's an Otome Game where Rin and her rival from the archery club compete for the coolest boys (amusingly enough, one ends up feeling rather skeptical of what merchandise is available).
Then Archer shows up. I had thought Rin was a Tsun Dere, but she's a million years to early to compete with this bittersweet jackass.
So far, I'm amazed by the writing, and how Nasu makes the characters likeable and attaching.
Then we get to school. Why does she go to school in the middle of a war, can't she take a sick leave? It's only a week or two, isn't it?
Well, I guess we must be thankful for that, because right after the final period the story takes a quick dive into creepyville.
So me and my servant Archer here, we looked at each other. And we said
Jokes aside, someone was trying to dissolve the student body, by dissolving the student's bodies, and using their souls to feed their servant.
Way to merrily jump over the Moral Event Horizon before even being introduced, Scumbag Magus.
And Tohsaka Rin and Archer get to show off their mettle in both power and mind, as they intelligently, proudly, and fiercely battle the Lancer who came to kill them.
