Takamura Yui

Takamura Yui is one of the main characters appearing in all versions of Muv-Luv Alternative Total Eclipse. In all her appearances, she is introduced as a strict and no-nonsense eishi of the Empire of Japan's Imperial Royal Guard. However, her fixation on all military-related things, and her own strict code of honor, works against her when it comes to getting acquainted with new faces, as well as matters of emotion. ~~Taken from http://muvluv.wikia.com/wiki/Takamura_Yui
