Naofumi has been scarred by the injustices he has suffered throughout his time in this world. And since a large quantity of those injustices were perpetrated by the Melromarc royal family, he’s instinctively distrustful of any Melromarcs, even Melty, who has shown him nothing but kindness.
As a result, he turns Melty away, despite the fact the Queen sent her to him explicitly to reconcile and undo the harm the King and Malty have done to him. It’s in Naofumi’s best interests to actually trust Melty and allow her to help him, but he just can’t, due to his history and stewing resentment.
But as the next Wave approaches, Naofumi still manages to run into a bit of good karma, as three warriors and two mages whose families he saved in Lute Village offer to join his party and fight beside him. He’ll only trust them if they cough up 150 silver pieces; hardly chump change.
He’s not the only one stiffing people: the cathedral charges fifteen gold pieces per person for the “class upgrades” he, Raphtalia and Filo will require in order to continue efficiently leveling up. When he produces enough for just Raph to be upgraded, an elder sister steps in presenting a decree from the king prohibiting them from providing any upgrades at any price.
If only Naofumi had heard Melty out rather than turn her away, he might’ve found an easier way around the king’s decree. Instead, he has to seek an upgrade through the slave dealer, who doesn’t provide that service but does offer to relieve Naofumi of five gold pieces in exchange for wyvern talons for Filo’s feet.
Filo’s new talons, combined with Raphtalia’s sharp new sword, make quick work of a job request to defeat a monster in the capital’s sewers. That night, as Naofumi dresses Raph’s wounds with holy water, Raphtalia worries about Naofumi’s vow that once all of the Waves are dealt with, he’ll return to his world, leaving her and Filo alone. The discussion is sidetracked when Filo wakes up and accuses Raph of getting “lovey-dovey.”
The next day they head out, encountering a village whose scant inhabitants are starving to death thanks in no small part to the actions of the Bow Hero Kawasumi Itsuki. Once again, the supposed heroic actions of a hero who isn’t Naofumi has appalling side effects.
Naofumi gets to finally confront both Kawasumi for what he did to the starving village, and Amaki Ren for the plague he caused by slaying the dragon. For their part, neither of them stuck around those places long enough to witness the consequences of their actions, and while Ren believes Naofumi, Itsuki doesn’t.
Naofumi’s distrust for everybody that isn’t Raph or Filo is matched only by the other heros’ continued animosity towards him. It’s a vicious cycle, and so far only Ren has taken a logical approach resembling reconciliation. The other two seem like lost causes in terms of ever seeing Naofumi as anything other than bad news.
We’ll see if despite that there will be any improved collaboration between the four heroes when the second Wave appears, which it does by episode’s end. By this time, the five Lute villagers scounge together the silver for Naofumi, who gives them the accessory they thought they were buying without taking their silver.
He tells them instead to use the cash to buy better equipment. They’ll need it in the battles to come. Naofumi doesn’t even trust these people, who owe their lives and those of their families to his heroics. But maybe, in time, he can, and that will lead to him trusting others who mean him no harm, like Melty and her mother the Queen.
