Summary
Being finished at the castle, Naofumi and Raphtalia head to the slave trader's tent to get Raphtalia's slave crest reapplied. Seeing Raphtalia's development under Naofumi, the slave trader offers to buy her back but Naofumi declines. On the way out they see a monster egg gatcha game and Naofumi decides to buy one. While doing his usual business in Castle Town, Naofumi is thanked by the Medicine Shop Owner and the Magic Shop Owner since Naofumi saved their families at Riyute Village during the wave. They give him gifts to help him on his travels.

While in Riyute Village, the gatcha egg hatched and Naofumi names the filolial Filo. While levelling up in the area, Filo grows incredibly rapidly and could be ridden within a day of being hatched. During that time Motoyasu and Malty show up at Riyute Village. They declare Motoyasu the new lord and lays extremely heavy taxes. Naofumi apposes them and, with the help of the ninja-like shadows, is eventually challenged to a race with Motoyasu for the village. During the race, Motoyasu's side cheats but Naofumi is able to win thanks to Filo's incredible power. The village then awards Naofumi a carriage a bill of passage to help his peddling operation.

One morning, Naofumi wakes up to find "Filo" missing and a young naked girl taking Filo's place. He finds out from the slave trader the the young girl is Filo which turns out to be a filolial queen which has transformation abilities.
