Now that Nai knows Karoku's bracelet has something to do with Circus, he goes in search of answers, but he finds that his earlier brush with trouble is far from over.

Yotaka has become a Varuga. Meanwhile Gareki feels very conflicted about his past with Yotaka and Tsubame.

Yogi going berserk sends the bad guys running, but when Nai senses that something is wrong with him, Tsukumo turns back alone, only to run into trouble herself.

As Nai and Gareki make their way towards the mysterious rainbow to see if Karoku is there, the rest of Circus work to wrap up what they can of the raid on the Kafka facility.
