Karneval

The Circus is a government agency made up of men and women with supernatural powers and the young Nai is on a journey in search of Karoku, a man who abruptly disappeared from his life. The only clue Nai has is Karoku's Circus ID bracelet.

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.

While under Circus's protection, a curious fact comes to light 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 their trip to Rainbow Forest, Gareki asks to drop by Karasuna, where they run into an old acquaintance of his. From this enounter, Nai and Yogi learn more about Gareki's past.

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

With Yotaka gone, Gareki and Tsubame are left to pick up the pieces and make sense of what has happened.
