Fridge Brilliance

 * Why is Yukari the main character of the manga, and Miho the main character of the anime? Part of Yukari's character is that she's very withdrawn because nobody else likes tanks the way that she does (until the tankery club starts up).  Internal monologue is all well and good for written works, but the slightly more social Miho makes an easier way to introduce the characters (especially since, like the audience, she's new to Oarai, so we get to meet her classmates for the first time along with her).
