Sayaka Yumi is a chick from Mazinger Z who was Koji Kabuto's gf. She was kind of brash and tough but still pretty hot. She piloted a couple chick robots that fired missiles out of their DD's and wernt as cool or tough as Mazinger Z (but a lot of guys with a robot-fetish loved em). She's a nice girl who cares for others bit can have a temper (like if Asuka from Evangelion wasn't totally awful. Srs. I hate her! She's awful! She didn't get enough beatings as a kid!) She also was in the 2nd and 3rd OAV's of CB Chara Go Nagai World
