Following the devastating war between the democratic Solar Alliance and the tyrannical New Empire, the galaxy was split into two zones separated by the Neutral Rim, a buffer between the two states.

Weakened by war, the New Empire collapsed from within in the Compact Revolution. A figure known only as VENICZAR ARCADIUS led the people against their Imperial oppressors. Following the New Empire’s fall, Arcadius mysteriously vanished from public view.

Soon after, another entity claiming to be Arcadius returned and declared the formation of PACT. With the vast production base of the former New Empire, PACT invaded the Neutral Rim with the intent of striking the Solar Alliance.

Arcadius sought the hand of the Ryuvian princess for reasons unknown, but was thwarted by Captain Shields of the Cera Space Force.

He was further thwarted at the battle of Far Port, when Cullen’s blunder lead to the destruction of the PACT invasion fleet by a much smaller Alliance vanguard fleet.

What was envisioned by PACT leaders as a glorious invasion into the heart of Alliance space instead became a bloody foreign campaign fought in the undeveloped Neutral Rim.

With the Alliance Fleet approaching PACT space and their initial military goals now in tatters, VENICZAR FONTANA betrayed Arcadius in the Battle of Helion and took control of PACT.

Now unmasked, the truth of the entity claiming to be Veniczar Arcadius came to light…

The self styled Sharr of Ryuvia, and officially it’s Queen.

She was formerly arranged by her father to wed Veniczar Arcadius in exchange for a non-aggression treaty from PACT, but managed to escape and later thwart the ceremony with the help of Kayto Shields.

Recently, she manifested incredible super powers in times of peril due to mutated engineered genes from the ancient Ryuvian era. Her awakening continues to become more and more powerful with each use. But her powers also bring a different personality unlike her usual cheerful and energetic self…

She has an unrequited love for the captain. However, the captain’s growing relationship with her best friend Chigara has prevented Asaga from pursuing her interest.

The Sunrider’s executive officer.

Strict, professional, and cold, Commander Ava Crescentia runs the ship with military discipline, despite the crew’s de facto position as privateers. She is a master organizer and can cut through paperwork and PACT hostiles alike.

Her inflexibility to the rules makes her unpopular with the crew, but she is the commander the Sunrider needs. She may confide to the captain that she is a poor leader, but in reality, she is the one truly in charge of the ship’s day to day operations.

She shared a relationship with the captain in her childhood, but has long abandoned any desire to rekindle their romance. Completely devoted to the safety of the crew and the liberation of Cera, she is willing to do whatever it takes to win the war.

Voiced byYomogi Kasumi


The Sunrider’s chief engineer.

She is a seemingly genius scientist who can perform feats of engineering which would be considered impossible by most standards. However, Chigara only nervously laughs and waves away any accolade whenever she pulls off a scientific miracle.

Her home world was one of the scientific centers of the galaxy, but was completely destroyed by a micro black hole in the Diode Catastrophe. The catastrophe was believed by experts to be an scientific experiment gone wrong, but Chigara maintains it was the work of sabotage.

Voiced byMurasaki Nina


The acting medical officer on board the Sunrider. Her medical credentials seem questionable, but seeing how the Sunrider had to leave port without a doctor, she’s the best the Sunrider has. Has a few screws loose in her head, and prone to forgetting things.

She appeared from seemingly out of nowhere and directed the Sunrider to one of the biggest discoveries of lost technology in the galaxy’s history. Despite being capable of missing the broadside of a battleship due to her weakness to motion sickness, Claude possesses a military grade ryder, called Bianca, with an unconventional electronic warfare suite. Where she acquired such a ryder remains a mystery. The captain has long suspected Claude of having ulterior motives for joining the ship, but she quickly waves away his attention with a strategic grope to his bottom.

Subject ofTeasing
Voiced byHaruna Ren


A mercenary who really has no interest in the captain at all. Really, why would you think she’d be interested in a loser like him.

She grew up in the rough parts of the galaxy and has a pragmatic approach to life. On the exterior, she is a confident and cold mercenary who can complete kill contracts without a second thought, but internally, she holds occasional regrets between jobs.

She has a rivalry turned begrudging friendship with the Alliance liaison officer Kryska Stares. While Icari correctly suspected Kryska’s divided loyalty upon Kryska’s first arrival to the ship, the two have since learned to trust each other.

Her ryder's name is the Phoenix and it specializes in close range combat.

The Alliance liaison officer on board the Sunrider.

Ostensibly there to coordinate efforts between the Sunrider and the Alliance Combined Fleet, Lieutenant Kryska Stares was viewed by the Sunrider’s crew as nothing more than an Alliance spy. Despite poor first impressions, Kryska gradually won the ship’s acceptance.

She has both boyish looks and personality, and is patriotic to the Alliance to the point of naivety. She views the Alliance Navy as a force of good in the galaxy and believes it can bring progress and democracy to the less civilized parts of the galaxy. She is proud of her rank in the Alliance and is a disciplined soldier who obeys military command without question.

She pilots a ryder called Paladin.

Voiced byNakase Hina


A cold and silent sniper from the ancient Ryuvian era.

She comes from a timeline two thousand years prior to the Neutral Rim War, when the Holy Ryuvian Empire stretched across the galaxy and the Infinite Emperor reigned from the star palace as a god. However, her time was one of strife, as her father, the crown prince, assassinated the Infinite Emperor, and placed the blame upon his half brother, Crow Harbor. The assassination sparked a civil war which threatened to destroy the Empire, unless drastic measures were taken. Sola, a child born from the former crown prince’s affair with a peasant girl, was kidnapped and impressed into service on board the Holy Empire’s ultimate weapon, the Sharr’Lac.

In the decisive battle against Crow Harbor’s fleet, the Sharr’Lac’s ultimate weapon was activated at the supposed cost of Sola’s life, and destroyed everything within a half light year radius.

Somehow, Sola then woke up two thousand years in the future and shortly afterwards joined the Sunrider’s crew.

Pilots the Seraphim, a Ryuvian ryder.

Enigmatic, serious and driven, Alice was the first Prototype whom the original Arcadius allowed into PACT's ranks after she ended up stranded in PACT space escaping from Diode during the events of the Diode Catastrophe, six years prior to the Alliance-PACT War.

She identified herself as being the Prototype who was responsible for taking up Arcadius' name, yet also denotes that she was simply the "last" person to claim it, showing she does not consider the other Prototypes who serve as "Arcadius" to be more then extensions of herself.

A feared space pirate, Cosette’s name is reviled through most of civilized space. She entered the life of crime starting at birth and now assumes control of much of the galaxy’s marauding pirate gangs. Despite her infamy, she is a folk hero among the poor for her brazen attacks on the richest nations in the galaxy. However, her brutal methods of retaining power and her merciless attacks on civilian vessels make her an unquestionable villain to most of civilized society.

She pilots a ryder call the Havoc.

Lynn was one of the many Prototypes that fought at the Second Battle of Helion and was ultimately overpowered and defeated by the awakened Sharr of Ryuvia, Asaga di Ryuvia. Out of all her "sisters", Lynn was the only Prototype to survive Asaga's wrath and was soon after taken captive by the Sunrider for interrogation, where she proceeded to begin sowing the seeds of distrust among the crew.

Dark and secretive, Fontana serves as the director of PACT’s secret weapons research. While ambitious, Fontana has proven himself loyal to Veniczar Arcadius. Fontana may be the second most powerful man in PACT, and is viewed as Arcadius’ right hand man. He also commands a fleet of PACT’s most technologically advanced ships, and is a ruthless villain who cannot be underestimated.
