Karneval

Nai is on a journey in search of Karoku, a man who abruptly disappeared from his life. All he has to go on is Karoku's bracelet, a form of ID for members of Circus - a government agency made up of men and women with supernatural powers.

Nai now 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.

Now under Circus's protection, a curious fact is uncovered regarding Nai's true identity. With that clue in hand, Nai, Gareki, and several members of Circus pay a visit to where they believe Nai came from.

After going to Rainbow Forest, Gareki asks to stop by Karasuna. There they run into an old acquaintance of his from whom Nai and Yogi learn more about Gareki's past.

Yotaka has become a Varuga and Yogi fights him, telling Gareki and Nai to return to Karasuna. Gareki feels very conflicted about his past with Yotaka and Tsubame, and what has happened to them now.

Gareki and Tsubame are left to pick up the pieces and make sense of what has happened now that Yotaka is gone.
