The Four Heroes head to the island of Cal mira for a bit of level-grinding before the next Wave. Naofumi makes a new friend in the form of L'Arc and his companion Therese Alexandarite, but are they really what they appear to be?
Tropes for this episode include:
- Cassandra Truth: When Naofumi tells L'Arc and Therese who he is, they don't believe him, thinking that the Shield Hero is some Obviously Evil Card-Carrying Villain and that Naofumi is going by a conspicuous alias.
- Disproportionate Reward: Having been commissioned by Therese to make her an Accessory; Naofumi is left completely flummoxed when he sees Therese in tears at the completed work that she promptly hands him all of her money for it.
- Draw Aggro: Naofumi's "Hate Reaction" technique works as this.
- Foreshadowing: Naofumi's party can't help but notice that Therese's incantation is different from normal.
- Friendly Fireproof: Therese's fire spell destroys the penguin monsters without hurting Naofumi.
- I Resemble That Remark!: When L'Arc describes what he had heard of the Shield Hero as a practitioner of "scams, blackmail, kidnapping... with powerful friends who will execute anyone he doesn't like", Naofumi remarks that that description as actually fairly accurate.
- Item Crafting: Naofumi manages to craft Raphtalia and Filo new weapons from a black bull monster. He later hand-crafts an accessory for Therese using her starfire crystal.
- Jerkass: The Three Heroes had left for the ship to Cal Mira early without Naofumi. They then occupy the entirety of the VIP rooms (including the captain's quarters) without the consideration of others.
- Meaningful Name: Therese Alexandrite draws mana reserve from crystals.
- Never Gets Drunk: Naofumi is absentmindedly eating a bowl of fruit at the bar, only for L'Arc and the bartender to try and get him to stop, pointing out that they make wine out of it. Thinking he has the same immunity (and not wanting to be upstaged by Naofumi), Motoyasu eats one too, only for him to start foaming at the mouth and collapse; nearly dying from alcohol poisoning as a result.
- No Listening Skills: While Naofumi tries to talk to the three heroes about their leveling systems, they are all too sea-sick to listen to him.
- Sinister Scythe: L'Arc's weapon.
- Translator Microbes: While Naofumi can understand Therese perfectly due to the translating properties of his shield, Therese has to use a spell for Raphtalia to understand her too.
- Wham Episode: There is a Dragon Hourglass in Cal Mira, and a wave is about to hit it within 2 days.
