Gareki comes face-to-face with the silver-haired Yogi in the darkened halls of the ship. Despite his attempts to get to the bottom of Silver Yogi's enigmatic words and to discover the truth behind this personality, Gareki is instead drawn into a dangerous game...

Faced with an impossible decision, Nai chooses to follow the other Karoku to the headquarters of the evil organization, Kafka. Upon arrival, the members attempt to extract new secrets about Incuna from the depths of Nai’s memory. Meanwhile, in a frantic attempt to find Nai, Gareki accesses Dr. Akari’s computer to track down confidential information…but get more than he bargained for! Circus’s secrets might finally be revealed…!

At Yanari's party, Nai and the crew deepen their friendships and experience the warmth that comes of supporting and encouraging one another. Upon their return to the 2nd Ship, Gareki is summoned to meet with a stranger, who has come aboard disguised as a tree...?! But back at Chronomé Academy, Kafka launches an attack, sending a swarm of Varuga to lay siege to the prestigious school. And when Tsubame attempts to protect her friends...she ends up a hostage herself! With Gareki back on board the 2nd Ship, who will come to her rescue?!

As the war for Alcia stretches from the depths of the Abyss to the Wall of Paradise, Licht and Tokikaze meet on the field of battle. The two brothers have been trapped by their love and hate for three hundred years, and their unleashed bloodlust rocks the very heavens. A word from Hina could be all that is needed to decide the match, but will she meet the same tragic end as her mother...?

Gareki's return to Chronomé proves to be short-lived, as a proposal from The Doctor leads him to begin studying at the Research Tower. Meanwhile, an unusual application of Jiki's powers on a captive Varuga provides Circus with a promising yet troubling lead on the recent outbreak of attacks. And with the appearance of a white bird, Nai falls into a deep sleep and somehow communicates with an unknown and mysterious entity...
