Before she knew it, Fena was on a small boat floating right in the middle of the Pacific Ocean! Escorted by the Otto and Salman who had aided her in her escape, she reaches a lone island surrounded by mist, Goblin Island.

After escaping their pursuers, Fena and the crew head towards Libar-Oberstein where the stone was manufactured. Fena, who had been frustrated from causing Yukimaru to be injured, pleads for her friends to teach her how to fight.

Now that they have unraveled the mystery of the coordinates, Fena and Yukimaru have managed to locate the location of Eden. In order to face the mystery her father left behind and the mystery of herself, Fena reaches Eden.

The crew reach the place filled with hidden treasure, but the British Navy appears and attacks the samurai. Yukimaru and Fena, who had ventured into the far depths, come face to face with Abel who had chased them down.
