In this labyrinth, where space and time can be curved or warped, Bocca is able to meet with the child sacrifice, Solo, as well as Kurofune. Bocca witnesses the battle between Horu and Kurofune that happened in the past. Horu was defeated but was able to survive by hiding in the labyrinth because of the warped time. Bocca parted ways with Kurofune and later got separated from Solo, so he wanders off by himself in the labyrinth.
黒船を求め迷宮をさまようボッカは、ソロと名乗る少年に出会う。
モンスターを見ても平気なソロに対し、メロスの戦士なのではと思うボッカ。
そして迷宮を進むボッカ達は、宿敵と戦う過去の「黒船」を見る。
