"A knight has something he must protect." An era in which samurai piloted armed horses, traversed the universe, and spent their days engaged in battle. Fourteen years ago, in the Kingdom of Grieve, where the protagonist Chizuru lives, an internal conflict erupted between the "First Prince's faction" and the "Elders' faction" while the king was away. The conflict subsided with the king's return, but it was ultimately attributed to the First Prince's rebellion and ended in victory for the "Elders' faction." Chizuru's father, a knight who belonged to the "First Prince's faction," was forced to commit seppuku (ritual suicide) for his involvement in the rebellion . Chizuru joined the King's Royal Guard to uncover the truth about her father's death and seek revenge, but she gave up on her revenge and, disgusted by the reality of the Royal Guard and the world of knights, which was different from her ideals, she was considering leaving. Around this time, Chizuru was assigned to look after Eiks Rocca, a troublemaker who had joined the Royal Guard, and a new life within the Royal Guard began for her.

From Infinity Studios: Sometimes in life, we have to stop what we’re doing to ask ourselves, “Why does such and such have to be like this?” The world of Katsuo Nakane’s Hurrah Sailor, deals with this question, as Konika, Ichino, Mareta, Shoya, and Ensign Kurie find themselves stranded on a planet whose inhabitants have developed virtually no technology at all. The Two United Empires and the Federation Kingdom have been at war for centuries and entire galaxies have been turned into war zones. With neither side ever achieving a decisive victory, the conflict has been dragging on so long that both sides have even forgotten the reason why the war originally started. But now, for Konika of the Federation Kingdom, and the others from the United Empire, they must put aside their differences to find a way off the planet together. During this process, they find that perhaps there are no differences between them, and some of them begin to wonder if they wouldn’t be better off not returning to the war.
