I'm the Heroic Knight of an Intergalactic Empire! (Manga) Vol. 3

Ever since she saw Count Banfield valiantly protect her home planet from space pirates, Emma Rodman has wanted to be a knight. She'd gladly give her life defending the innocent and protecting her lord's domain. Unfortunately, her final test at the knights' academy has earned her a D-ranking, the lowest of the low! What a disaster! Now she's relegated to a remote border planet, and her squad are a bunch of useless layabouts. Should she call it quits? Or will this isolation give her room to grow and shine?
