Шіморенджяку Йоко

The sweet, short and pink- haired Yoko is used mainly as the comedic character in the series.

She is very fond of sweets and junk food, gets rather nasty when she's drunk, and has a pet bat (Chi-chan) who bites people who are either scary or just new to him. Her bat serves as the team's mascot. Yoko is known for having an annoying high voice (in the dub anyway) and is prone to small fits of immaturity and child like behavior.

Yoko is the least experienced pilot and is nowhere near as good as Mitaka or Miyuki, as Kengamine Kouji once stated "Yoko is the kind of pilot who got her license out of a cereal box."
