Ruch (ルフ Rufu?) is a character from Valkyria Chronicles 4. Edinburgh Navy sergeant, and tracker of the Centurion. As a prodigy who skipped grades to graduation at Navy Training School, she is familiar with the latest technology, and joins the fleet after her abilities were recognized.
Ruch does not talk to anyone much, perhaps because of serious and level-headed character, or strong tone of voice, but is close with Mary.
