The anime 's title was inspired by the principle purpose of the Nameless : to suffer in battle for the goals of others . A subtitle attached to the project during development was " The Road to Kubinka " , which referenced the Kubinka 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 was 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 was 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 , " Akari ( Light ) -Tomoshibi- " ( 灯 @-@ TOMOSHIBI- ) , was sung by Japanese singer Faylan . The ending theme , " Someday the Flowers of Light Will Bloom " ( いつか咲く光の花 , Itsuka Saku Hikari no Hana ) , was sung by Minami Kuribayashi . Both songs ' lyrics was written by their respective artists .
