Mogami

"Mogami is a frank, upbeat, energetic, and tomboyish girl. Due to having collided three times in her historic service, she's also commonly portrayed as quite clumsy, and too eager to watch where's she's going. Although all three collisions were with three different ships, collisions with Mikuma are most commonly portrayed, as she is a sister-ship, and artists tend to keep sisters in their own cliques. Because of her short hair, boyish tone and the fact she wears shorts, she is often portrayed as the target of rumors of being a boy, or outright portrayed as one." From http://kancolle.wikia.c...
