Yuri Ajin Books in Order

Betrayed and killed by someone he loved, an underground fighting champion awakens as a boy named Kai in another world. Martial cultivation offers him a new path to power, but survival demands that he learn its unfamiliar rules.

A disastrous expedition leaves the Fallen Star Sect reeling, while a tragedy at the imperial palace threatens civil war. Kai travels east, seeking recovery, strength, and a place beyond the spreading turmoil.

After losing the family and home he had found, Kai pursues answers and revenge. His journey leads through an ancient city toward Alkea's capital, where his sister Julie and a powerful sect offer new possibilities.

The opening of the Indestructible Tower turns celebration after the Great Tournament into slaughter. Kai escapes with five others into an unfamiliar world, where he must continue cultivating his powers while searching for a way home.

Five years have passed as Kai advances within the Cloud Abode and earns a place on its First List. His pursuit of greater strength now carries him into another journey, with fresh challenges beyond his earlier achievements.

Passing through the Gates of the Ecumene leaves Kai injured and isolated in an unfamiliar world. Surrounded by strange dangers, he searches for other humans while confronting a harsher path toward mastery of his abilities.

Having escaped slavery and recovered from his injuries, Kai reaches the Cloud Abode with his companions. Among elite warriors, the group must prove its worth in a struggle where failure carries consequences far beyond wounded pride.

War and the hunt for ancient treasures bring rival peoples into conflict, while Kyros the Soul Thief faces formidable competition. As another world opens, Kai pursues an old promise and the truth behind a divine legacy.

Control of Avlaim gives Kai responsibilities that personal strength alone cannot fulfill. Building an organization and rescuing friends draw the attention of powerful factions, forcing his Temple to confront enemies beyond its fragile regional foothold.

Kai survives a brush with death in the Trials World but loses part of himself in the process. Recovering what was taken forces him to reconsider leadership, as raw power and determination no longer guarantee control.

Reunited with friends and recovering his memories, Kai hopes to leave the Trial Worlds and reach Julie. The collapse of three worlds instead unleashes ancient powers, drawing his Temple into a struggle over a changing order.

With the Temple ascendant, Kai hunts the Manticores and seeks control of Bellum. Yet the purpose of the Trial Worlds is nearing fulfillment, and their masters face a final ordeal in the Heavenly Exaltation Pagoda.

Kai's return to Sanctum brings urgent complications instead of respite. With the Ecumene's overlords confronting the invading New Army of Truth, he must choose where to stand and prepare for a conflict that threatens everything around him.

The Temple and its empire emerge into the Ecumene after leaving their dimension behind. Kai draws closer to Julie, but establishing their place means confronting the Otrey Corporation and the revived forces of an old enemy.

A new Great War tears through the galaxy as an ancient struggle approaches its climax. With once overwhelming powers reaching their limits, survival depends on uncovering deeper secrets of cultivation before the Ecumene's strongest competitors claim victory.
