Haruka Armitage

Haruka is a headstrong and impulsive Meister Otome, known as the Topaz of the Jewel Isles. Early in the story Haruka is a role model for Arika Yumemiya, and tells her that an Otome needs "Strength, beauty and guts" before hurtling a spaceship away bare handed. She was classmates with Shizuru and there are hints in the series of a rivalry between the two. Her element is the same ball and chain mace weapon of her My-HiME manga counterpart, and her Element attack is called Dynamite Crusher. Her master is the President of Aries, and her best friend, Yukino Chrysant. (Source: Wikipedia)
