After Queen Mirellia Melromarc's death, Trash conducts Melty's coronation as the popular new queen. After the ceremony, Naofumi's party congratulates Melty. Naofumi teases her about her new responsibility so Melty retaliates makes him an archduke to his dismay. Upon hearing this, Trash proudly approves and reminds them that as an archduke, the two of them are technically engaged. Both Naofumi and Melty try to refuse but their pleas land on deaf ears and their engagement remains

Chapter One: Talk of Love
Naofumi heads back to his village after the coronation ceremony and on the way he meets Ren and Eclair. Naofumi and Ren discuss what they want to do when they defeat the waves. Ren hasn't decided whether he wants to stay or go back to his world since he's now made relationships that he values deeply - including Eclair. However, Eclair seems oblivious to his affections and doesn't seem to be ready for a romantic relationship. Naofumi encourages Ren while Ren and Eclair teleport to the Melromarc's castle.

Chapter Two: Limit Break
Heading further into the village, Naofumi meets up with Ethnobalt who had recently crossed over from his world. According to Ethnobalt, they have three days before they can cross over again. Naofumi plans to take advantage of this time to level up and prepare. The first thing on his agenda is to use Gaelion's new knowledge as Dragon Emperor to break the level-100 limit for their party. Everyone who was ready got the level breaking ceremony including Sadeena, Shildina, Raph-chan, and Raph-chan II. After the ceremony, Naofumi went training in the ocean with Sadeena, Shildina, Ruft, Raph-chan II, and Ethnobalt. Sadeena and Shildina both test out their massively improved abilities and Ruft reaches the level 40 limit. Back on land, Ruft receives a special class-up from Raph-chan and is sent to learn leadership with Melty. Using the experience-rich seabed, Naofumi and Ethnobalt train the remaining 3 days until Ethnobalt reaches about level 100 and Naofumi reaches level 150. Finally, Naofumi heads over to Erhard's shop to upgrade his equipment to be compatible with Ethnobalt's world.

Chapter Three: Party Selection
The day before Naofumi leaves to Ethnobalt's world, he and the other Legendary Heroes meet up and discuss who should be on the rescue party. According to the shield, he can bring multiple people along but are limited by the number of legendary heroes. Filo and Rishia were selected since they previously went to that world and their levels would only be reset to what they were over there. Itsuki, S'yne, and Raph-chan volunteer and are accepted into the party. Sadeena is allowed to come while her sister was eventually convinced to stay to protect the village. The rest plan to stay at the village.
