Jinto, who has finished his training, also joins her crew as a supply officer. They are attached to the imperial fleet assigned to defend the strategically important Laptic Gate from a force 15 times larger than their own. And to make things more worrisome, not only is their commanding officer the younger sister of the third baron Febdash, the admiral of their fleet and his chief-of-staff are from the Bebaus family notoriously known for their "Spectacular Insanity".

On the way, Jinto encounters his friend Dorin Ku and is informed that a military war game will be held in the Hyde star system. Martine, the system's capital, refuses to surrender to the Abh Empire. Count Jinto negotiates with the Martinese government and seeks terms of surrender. At last, at the cost of the planet's autonomy and exile of the Count, Martine joins the Empire.

The main characters have returned to the Imperial fleet and Lafiel is now captain of a new ship, the assault frigate Flicaubh. Lafiel's younger brother Duhiel enlists in the navy and is dispatched to a battleship. The so far neutral Hania Federation unexpectedly offers to join the Abh Empire and Empress Ramaj accepts. While Jinto and Lafiel are returning to the Imperial capital, Lakfakalle, the Hania Federation fleet suddenly attack the Abh Empire and advances towards the capital.

Unable to recall the fleets in time to mount a defense, the empire prepares to abandon its capital for the first time in its history. The empress leads the small fleet available to meet the enemy in a desperate attempt to buy time for the civilians and crucial production structures to be evacuated. Meanwhile, Lafiel and Jinto are assigned to an old cruiser and tasked with transporting the Memorial Stones, markers etched with the name of every person who has ever died for the empire and important cultural artifacts. At the same time Duhiel is trapped behind enemy lines, and his superiors must get him back to Imperial territory.
* Banner of the Stars VI "Thunder of the Empire" (星界の戦旗VI 帝国の雷鳴) (Seikai no Senki VI "Teikoku no Raimei") (2018)
The war got stagnant for a long decade after the fall of Lakfakalle. Now the Empire is split in two, and both parts of it are undermanned and have problems with proper supplies. Both the Alliance and the Empire are slowly building their forces to break the stalemate which has occurred after the fall of Lakfakalle. Finally, the Empire is ready to initiate the operation "Thunder", launching their attack at People's Sovereign Union of Planets in order to reunite the shards of Imperial controlled space and, if possible, annex the territory and secure the resources of the Union. Lafiel, the Crown Princess, and, as required by the title, the Admiral of the Fleet, is ordered to complete this operation using the forces she helped to train and amass on her previous assignment during past decade. She has to handle the lack of supplies and not quite experienced crews while taking over a whole star nation, all while being overlooked by one of the Imperial Elders and tempted to go beyond the operational orders.

### Anime

Among fans, Banner of the Stars is a title used to describe all anime except Crest of the Stars (which Hiroyuki Morioka has said was not intended as the main idea of the story, but just an introduction to how Jinto and Lafiel met). Two TV series and an OVA have been released adapting the first three books. Bandai Entertainment released Banner of the Stars I and II seasons in North America in 2003, and in 2013 Funimation re-licensed the series and released them along with (subtitled-only) Banner of the Stars III in a 2018 DVD compilation. On December 25, 2019, Banner of the Stars along with Crest of The Stars was released on Blu-ray in Japan.

### Radio drama

FM Osaka broadcast radio drama adaptations of Banner of the Stars novels and they were later released on CDs. The latest episode, Banner of the Stars IV, was broadcast in 2006, but has not been released on a CD.

### Manga

One-volume manga adaptations of the Banner of the Stars and Banner of the Stars II anime series have been released by Dengeki Comics on October 27, 2001 and July 27, 2002, drawn by Toshihiro Ono and Wasoh Miyakoshi respectively, after they were serialized in Monthly Comic Dengeki Daioh magazine in 2001 and 2002. The manga volumes were released in English by Tokyopop on August 3 and October 12, 2004 under the names Seikai Trilogy, Vol. 2: Banner of the Stars: The Shape of Bonds and Seikai Trilogy, Vol. 3: Banner of the Stars II: Protecting the Precious. These volumes were referred to by Tokyopop as the second and third parts of the Seikai Trilogy. This was because at the time of publishing, only three anime series were adapted from Hiroyuki Morioka's works, and Banner of the Stars III was yet to be made. Crest of the Stars was considered the first part of the trilogy.

### Video game

The Banner of the Stars series was adaptated into a Japanese video game for Windows. Named after the series, Gainax released it on September 26, 2003. It is a member of the wargame genre, featuring interactions with some characters from the novels in-between the battles. A port for the PlayStation 2 console was released on April 21, 2005.
