Personality
Umi is logical, kind and down to earth but is very lazy. She is a third year student at Kawai High School, and is one of the so called 'founding members' of the Defense Club. Umi is very sharp minded displaying more leader ship capabilities when the team needs it the most. She is very detailed, always day dreaming and wondering about things that aren't so important. Even though she is laid back and hates to move around, she is an amazing athlete. Umi is also a very lucky person gradually geting high marks for tests she doesn't study for.
