Yumi Ishiyama

Yumi is a main character from Code Lyoko and one of Nico D's 5th favorite character!

Appearance
Yumi likes wearing black, and all her clothes (and her hair) are that color. Basically its the american goth look, black sweater, black pants, and black boots.

In Season 4, she wears a dark gray blouse, gray pants, and the same boots as in season 1-3

Personality
Aside from her complicated romance with Ulrich, one of Yumi's other main character focuses is her parents' rather unstable marriage, which has proven to be a major strain on her from time to time. Her father and mother can often be heard bickering in the background whenever an episode takes a focus on her home, and at one point, her father even left the house and shortly resided with a friend of from work. This is shown to have had a major strain on Yumi as she struggled to understand why her parents were arguing in the first place.

Although it is often dismissed, she is seen to have a small attraction to William which is often seen at many points in the series. Despite this, Yumi claims he is nothing more than just a friend. These feelings are never ventured, however, rather than just a minor attraction.
