Raphtalia insists to get another slave seal as a symbol of faith to Naofumi. While there, Naofumi buys a Filolial egg which later hatches into a small bird and named it Filo. Similar to demi-humans, Filolials grows quickly as it levels up. During their visit to Lute Village, Naofumi was alarmed to see Motoyasu and Malty imposing heavy taxes to the villagers. Naofumi tries to interfere but the Queen’s envoys suddenly appear and gave Malty a message. Disturbed by the message, Malty challenges Naofumi to a race where the winner acquires the village. Despite Malty’s guards using magic to cheat for advantage, Naofumi and Filo still manage to win against Motoyasu and his dragon. As a reward, Malty and Motoyasu left and the villagers offer them a carriage and Trader’s Pass. The next day, they woke up surprised to find Filo transformed into a little girl with wings.
After defeating the Wave of Catastrophe, a celebration was held at the castle for the four heroes. Myne told Motoyasu that Raphtalia was a slave, which leads to Motoyasu challenging Naofumi into a duel for Raphtalia’s freedom. Naofumi refuses the challenge but the King demanded the duel to take place. Raphtalia tries to explain but she was immediately seized by the King’s guards. Even though Naofumi was 22 levels behind, he still manages to have an edge against the Spear Hero. As he was about to strike the final blow, wind magic from Myne trips Naofumi into losing the fight. While they were removing Raphtalia’s slave seal, Naofumi realises that everything was set up and his burning hatred for it unlocks the “Cursed Series”. Raphtalia slaps Motoyasu for assuming she needed saving and runs toward the defeated Naofumi to calm him down and defuse the “Cursed Series”. Itsuki and Ren call out Myne and the King for allowing such cheating. The following morning, Naofumi’s confidence was restored knowing Raphtalia would always be on his side.
