Zagan’s group travels to Nephy’s old home, the hidden elven village in the northern holy lands, to learn the secrets of the high elves. Upon their arrival, however, they get trapped in a time-distorting barrier and Nephy gets transformed into an adorable little girl. Who would do such a thing?! And exactly what is their objective?! Zagan is unsure what to do, as Nephy has reverted to a time from before she knew suffering. He’s forced to ask himself—does he have any right to restore her when she’d be happier living inside the barrier as an innocent child forever?

On to the honeymoon! Zagan has decided to introduce Nephy to Orias both as a means to cheer her up from her anxieties of healing Kuroka's eyes, as well as to gain more information on Archdemon Shere Khan. However, Orias herself has vanished, leaving behind the message, "I'm going to retrieve Azazel's Staff." Thus, the two of them depart for the Holy Cut, the headquarters of the church, to chase after her. And in order to avoid any unnecessary suspicion, they decide to pose as a newlywed couple!

Zagan is feared by the masses as an evil sorcerer. Both socially awkward and foulmouthed, he spends his days studying sorcery while beating down any trespassers within his domain. One day he's invited to a dark auction, and what he finds there is an elven slave girl of peerless beauty, Nephy. Having fallen in love at first sight, Zagan uses up his entire fortune to purchase her, but being a poor conversationalist, he has no idea how to properly interact with her. Thus, the awkward cohabitation of a sorcerer who has no idea how to convey his love and his slave who yearns for her master but has no idea how to appeal to him begins.

Nephy learns of Zagan’s impending birthday from Alshiera, which is information that Zagan himself doesn’t even know. Seeing this as an opportunity, Nephy leads the charge in putting together a surprise party for him, but with her past experiences being what they are, she has no idea how birthdays are celebrated. Meanwhile, Zagan also learns from Orias that Nephy’s birthday is coming within the month, and the two Archdemons decide to mark that day as Nephteros’s birthday as well. Much like Nephy, however, Zagan is ignorant of how birthdays work as he tries to plan a surprise for her. The entire castle is in a celebratory mood, but dark clouds loom over the horizon. Zagan knows of a terrible problem haunting Nephteros that has to be addressed before any sort of celebration is an option, and he still has no idea how to resolve it. What’s more, after a month of relative peace and quiet, Shere Khan and Bifrons finally make their move.

In order to thank Zagan for building the castle's grand bath, Lilith offers to use her powers to help Zagan and Nephy enjoy a date within their dreams. But will that really work out, considering their devastatingly poor sense of imagination? Meanwhile, the hunt for Shere Khan intensifies as more Archdemons reveal themselves and the looming threat Alshiera has been fighting draws ever closer.

With Chastille’s birthday quickly approaching, Barbatos is at his wits’ end and goes to his friend for advice. However, at the exact moment, the bewitching Archdemon Eligor appears to recruit him. Shortly thereafter, Chastille witnesses Barbatos spending time with a gorgeous woman and decides to secretly tail them. Tremendously misunderstanding what she sees, she can no longer suppress her own feelings. “That man is mine! Get your hands off him!” It’s finally time for Chastille and Barbatos to take center stage in this volume of Elf Bride!

The battle between Archdemons may be over, but Zagan still has plenty of problems at hand. He doesn’t have a birthday present for Nephy yet—and the special day is closing in fast! What’s more, now that the group knows of Shere Khan and Lisette Dantalian’s fates, they’re also determined to mend the relationship between Angelic Knights and sorcerers. Their solution? Leaving it all to an unrestrained Gremory! And most pressingly, hundreds of Shere Khan’s Nephilim survived the conflict. Since these resurrected heroes of the past can’t be left to roam, Zagan creates a town for them and decides that his beloved daughter Foll will be in charge! She’s extremely motivated to succeed at her first big job, but then a wounded girl with no memories appears out of nowhere...
