As Naofumi, Raphtalia, and Filo continue mopping up the beasts and healing all the villagers, they come across a nobleborn-looking girl among a pack of lesser filolials (which Filo thinks look tasty, the cannibalistic little imp). The girl, who introduces herself as “Melty”, falls in love with the far larger and talking filolial, and the two become fast friends.
That night, she comes to Naofumi’s inn, requesting an escort back to the capital. As she’s nobleborn, Naofumi assumes he’ll get a handsome reward for returning her to safety, and so accepts.
But one of the queen’s spies is watching. While there’s more to Melty than meets the eye, she ends up loving riding in the Filo-drawn carriage, and at night strips down so she can sleep within Filo’s dense, thick, luxuriously soft feathers (great Foley work on those feathers).
When they reach the capital, Filo escorts Melty home, while Naofumi and Raph make a beeline to the cathedral, where they meet a particularly haughty and patronizing Pope.
He (or rather one of his nuns) tries to sell Naofumi a bottle of crude holy water for the exorbitant price of one gold coin, but his HUD detects its cheapness, and he ends up with a bottle of the pure stuff. So mission accomplished: Raphtalia should be good as new in no time.
Unfortunately, since they’re in the capital, Naofumi is naturally uneasy about anyone approaching him. When a young, flustered guard does so, he and Raphtalia run away, eventually splitting up to lose him.
In the process, Motoyasu and Malty find Naofumi, and challenge him to yet another duel, since Motoyasu has fallen in love with the girl with angel wings following Naofumi around. He assumes she’s another slave and demands he free her.
This results in a huge dust-up, in which the many city bystanders not only have to dodge Motoyasu’s deadly attacks (he causes quite a bit of collateral damage, the bastard) but end up fighting each other over whether it’s cool for the two heroes to go at it in such a crowded public space.
Ultimately it’s Melty who breaks up the fight, and in the process reveals she’s not only Malty’s younger sister, but heir to the throne, as Malty is a problem child deemed unworthy to succeed the king.
She seems poised to join Naofumi’s party…right up until Naofumi tells her to get lost. He presumes that anyone related to Malty and the king cannot be trusted, and is trying to lull him into a false sense of security so she can stab in the back later.
There’s absolutely no evidence or indication Melty’s intentions are anything other than earnest and good, but I guess Malty did quite the number on Naofumi. There’s really no one he trusts other than Raph and Filo…which could well end up being detrimental to him.
