Duke Ariabart Tytania takes his fleet into battle against the vastly outnumbered Eurian fleet commanded by Fan Hulic. But Hulic, a new officer with little experience, has a little surprise waiting for the Tytanian fleet…

Lord Ajman Tytania meets with his four dukes to review the Battle of Cerberus, and discuss the actions to take in wake of its outcome. His thoughts also turn to determining which of the dukes should succeed him as clan lord. Meanwhile, Fan Hulic finds his reception upon his return to Euria very different from what he had imagined.

Fan Hyulick arrives in Emmental, and is taken by Tytania forces to Alses Tytania, who offers him a position within Tytania. Fan accepts, but Lira rescues him from Alses's mansion, hoping he will join their resistance force and defeat Tytania.

Lira tries to seduce Fan so that he joins her resistance force, but is interrupted by Tytania forces who were informed of Fan's whereabouts by Lira's grandmother. Lira refuses to give in and helps Fan to escape, where he meets Miranda Casmier and joins her forces on a ship named "The Honest Old Man".

After the battle of Cerberus, Tytania is clearly not invincible like it appeared, so Turandia officials decide to rebel. Jouslain arrives in Turandia to resolve the issue before a battle broke out, but fails and after he leaves the Turandia princess is shot.

Turandia, unable to gather allies, rebels against Tytania alone. To make up for his loss in the battle of Cerberus, Ariabart commands and after a short battle squashes Turandia.

Fan and Miranda's group visit another resistive force, and watch them take over a Tytania fortress as part of a plan to defeat Tytania.

Zarlisch defeats the resistive force that took over the Tytanian fortress, and Elbing is forced to give Tytania their mines to prove their loyalty. The Elbing princess, Lydia, realises that this would be a disaster for her country, and instead sacrifices herself as a hostage of Tytania.

Lydia goes on an adventure around the Tytania mansion in order to talk to Ajman Tytania about her becoming a hostage to prove Elbing's loyalty, but in the end Jouslain passes on the message.

Euria collapses after an attempted rebellion, and Lira is kidnapped by Alses Tytania, after being betrayed by one of her comrades, to lure Fan out and capture him.

After learning of Lira's capture, Fan makes preparations to save her.

Fan Hyulick goes to Alses Tytania's mansion to rescue Lira Florenz, but Alses stops him from completing his mission. In order for Fan to escape, Lira attacks Alses, but dies in the process.

Alses tries to escape from Emmental, but before he reaches the safety of Idris' fleet, Fan Hyulick attacks his ship, killing Alses.
