 The anime 's title was inspired by the principle purpose of the Nameless : to suffer in battle for the goals of others . A <unk> attached to the project during development was " The Road to <unk> " , which referenced the <unk> Tank Museum in Moscow . The game 's main theme was how the characters regained their sense of self when stripped of their names and identities , along with general themes focused on war and its consequences . While making the anime , the production team were told by Sega to make it as realistic as possible , with the consequence that the team did extensive research into aspects such as what happened when vehicles like tanks were overturned or damaged . Due to it being along the same timeline as the original game and its television anime adaptation , the cast of Valkyria Chronicles could make appearances , which pleased the team . The opening theme , " <unk> ( Light ) <unk> " ( <unk> @-@ <unk> ) , was sung by Japanese singer <unk> . The ending theme , " <unk> the Flowers of Light Will Bloom " ( <unk> , <unk> <unk> <unk> no <unk> ) , was sung by <unk> <unk> . Both songs ' lyrics were written by their respective artists .
