Miyuki Otonashi (音無 美雪?) is a biologist working for the Otonashi MiyukiU.N. in the 2004 Godzilla film, Godzilla: Final Wars. She is one of the members of the Gotengo's crew after the mutants fall to the Xiliens.
Miyuki is very defensive of her position as a female contributor to science, making many demeaning comments about Shinichi Ozaki when he teases her about it. She is one of the scientists who identifies the Xilien M-base in Gigan's tissue, and does much research on it. She was not meant to be a crew member aboard the Gotengo, but she briefly becomes the pilot after the real pilot is injured, and Ozaki has not yet arrived. She seems to have a very detailed knowledge of M-base.
Based on her first few scenes, one could draw the conclusion that she is a cynical person with little compassion to those who do not match her intellectually, but later on it is shown that she cares about the well being of her team and the Earth.
