Ep. 17: Naoki rastreia Moress até um portal de santuário e desafia Serra para um duelo de cartas de alto risco.

17

While in the city with Shingo, Naoki spots Moress and manages to track him down, seeing the butler use a gateway like the one Gaillard and Kourin previously used. Naoki tells Kai and his friends about his discovery, and despite it possibly being a trap, the group decides to use the portal anyway. They find and activate the gateway, which transports the team to a sanctuary separate from Earth. Kai and his friends are shortly confronted by Serra and Moress, with the former telling them that Aichi is sealed here and that defeating the Quatre Knights will lift the seal. Serra also informs them that whoever loses in a cardfight held within the sanctuary will also lose their memories regarding Aichi. Naoki decides to fight against Serra, who is now using a Granblue deck. In the middle of the fight, Serra reveals his family history and practices. His family would ruthlessly cut off any kin who loses in a cardfight, and Serra himself has done so, which has shaped him into becoming the cold-hearted person he is now. Although afraid to lose his memories about Aichi, Naoki regains his confidence and prepares to go on the offensive. (Source: Wikipedia)
