Leaving behind his homeland, Zinkenstill, Gran continues his journey with the other skyfaring crew members, hoping to reach the Island of the Astrals.

Gran and the others are on the run from the Erste Empire, when out of the blue, the Empire proposes peace talks, and the crew heads to the Albion Citadel for the negotiations.

Gran and his crew are acquitted, thanks to the Erste Empire's pardon. But the morning after the banquet, they wake up to find Katalina gone, having left behind only a letter.

Due to a past incident, Katalina feels indebted to Vira and wants to provide her support after the many years of pressure and loneliness Vira has endured as Lord Commander.

Releasing the primal beast Luminiera's power, Vira attacks Gran and the others. When she sees Vira in berserk mode, Katalina is consumed with guilt. And so she makes up her mind to face up to Vira's feelings, to make up for the past.

After leaving Albion, the Grandcypher lands on an island shrouded in thick mist, notorious for being inescapable.

Lyria, Io, and Orchis have been swallowed by Celeste. Left behind, Gran and the others search for a way to save them, along with a ghost girl, Ferry, whom they met in the village.

Celeste is being manipulated by someone. Someone who has forced the primal to attack the village and devour its undead residents. Gran takes the chance to leap into Celeste to rescue Lyria, Io, and Orchis.

Gran and the others head to Golonzo Island, known as the mecca of shipbuilding, in order to repair the damaged Grandcypher.

Under the command of Pommern, the imperial army takes Gran and Lyria away. Meanwhile, Noa is held captive in a research lab as he suffers from the effects of dark essence.

Gran and Lyria escape from the empire's garrison and are reunited with Rackam and the others. Noa tries to resurrect the Grandcypher that had been damaged by the empire's strike, but finds himself too weak to provide sufficient power. He suggests they ask Mithra, the primal beast of promises on Golonzo, to help them.

The Black Knight, trapped by her own past, is set on attaining Lyria's power, but Gran vows adamantly to protect Lyria. Their unwavering beliefs clash, neither willing to bend.

Djeeta and the crew head to an ancient castle after hearing rumors about the Wish Egg, a fairy tale treasure said to grant any wish.

Far away on a remote island, Gran steps into the ring for an exhibition match of ritual proportion. Once a year, top fighters from around the island must gather together for a duel to appease the gods, and anything less than victory could spell grave disaster for the locals. After grinding through some grueling training to master the art of wrestling, Gran enters his match as the mysterious masked fighter, the Masked Cypher. / Djeeta is just an ordinary student at St. Albion Girls' Academy, who one day, while spending some time in the animal shed, finds herself smitten with her upper classman. That upperclassman's name is Katalina, who is renowned for both her wit and beauty. Even as Djeeta shrinks back from Katalina's majesty, the two gradually grow closer. Unbeknownst to them, however, not everyone is excited for their newfound affection.
