Nadia Naofumi is taken out for drinks by the mysterious woman, Nadia, when they are ambushed by several of their competitors who forfeited, who they easily deal with. Naofumi and his party restock on items at the local shop, where he gets acquainted with the famous merchant who runs it. With all the fighters forfeiting, the finals are set for Naofumi's team against Nadia. Using her lightning magic, she proves to be difficult for them to fight, even moreso when she transforms, revealing herself to be a killer whale demi-human. However, Raphtalia recognizes her, calling her "Sadeena", which causes her to stop and recognize both Raphtalia and Naofumi. Realizing his intentions to win the prize money to free the Lurolona slaves, which she was also doing, Sadeena throws the fight. But then, the sponsors stop Naofumi from winning, forcing them and Sadeena to team up against a new challenger, the mysterious "Murder Clown", who commands several puppets. Raphtalia and Filo fight it head on, while Naofumi and Sadeena cast a choral spell, granting Raphtalia an increase in power. She seemingly defeats the clown, but they escape using a dummy at the last moment. Murder Clown gives Naofumi vague warnings about the future before disappearing. The sponsors once again attempt to prevent Naofumi from winning his earnings, but the slave and shop merchants intervene, revealing his identity and backing them up. Meanwhile, Fohl picks up medicine which he takes to his gravely injured sister, Alto.
