Not afraid of things and speaks her mind clearly, so she might be seen as a selfish person. However, she cares deeply about her friends. She uses rapiers well because she fences. She learns Water magic. The tallest of the three Magic Knights (by a little). Umi has long light blue hair and blue eyes. Her school uniform consists of a blue skirt over black tights (which she thankfully loses when she gets her armor) and a blue jacket with an orange tie. She also has blue boots. She's short-tempered and she over reacts to anything strange or unpleasent. She has trouble dealing with strange things ("This lake is too weird! From now on you're known as the 'Weird Lake Eteruna'!!") She constantly fights with Mokona (as much as you can fight with someone who has a one word vocabulary). Somewhat clueless when it comes to men. The Ooba no Shoujo.
Umi is my favorite(next to mokona). I like her antics and her charm. I also like her temper...it's so much like my own.
