The world is abuzz as centuries of hostilities between sorcerers and Angelic Knights have been brought to a screeching halt by the now-widespread knowledge of the relationship between Chastille and Barbatos—disregarding whether they admit to actually being in one. Meanwhile, Zagan begins his research into how to destroy the Sacred Swords so that he can free the seraphs sealed within them. At the same time, faced with various challenges like Marchosios’s scheming and the demons’ arrival, he plays his next hand: to begin negotiations with the oldest living Archdemon, Forneus. And who better for the job of dealing with an idiosyncratic Archdemon than the brand-new couple, Shax and Kuroka?

After easily repelling the armored assailant who coveted the power of an Archdemon, Zagan finds she is actually a little girl, and a dragon! As punishment for attacking him, Zagan orders the little dragon to... help Nephy with her chores? Meanwhile, Chastille finds herself in trouble for refusing to take part in Zagan's subjugation. A new Archangel arrives in town, rumored to be after the apostate Chastille's life and looking to crown Zagan as his 500th kill.

A month of peaceful days have passed since Bifrons's hectic evening ball. Having gained many new followers, Zagan's castle is now bustling with activity. After everyone has settled in, Nephy asks Zagan if she can visit her old home to find information on high elves. As such, the group heads off to the northern holy lands, to the hidden elven village, but somebody is already there awaiting their arrival...

It's a kind of magic! Love and sorcery continue taking root in more ways than one as Zagan is faced with Angelic Knights, snarky friends, and... a council of Archdemons?! Can he manage to get Nephy through Magic 101 and achieve his own goals? Or is their relationship as doomed to fail as Zagan's attempts at domesticity?

It's Lonely at the Top! Upon inheriting the Sigil of the Archdemon, Zagan suddenly thrusts Nephy away from his side. The distance between them was gradually shrinking, so why the sudden change? And who's this guy attacking the local tavern? The one pulling the strings behind the curtains finally reveals themself and chaos ensues as the truth begins unravelling.

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.

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!

The world is abuzz as centuries of hostilities between sorcerers and Angelic Knights are brought to a screeching halt by the now-widespread knowledge of the Chastille and Barbatos's relationship--regardless of whether they admit to actually being in one.

After months of relative peace and quiet, things aren't looking good for our heroes. It appears that Bifrons's plans are finally coming to fruition. Not only has Nephteros been possessed by Azazel, but thanks to that, Alshiera has vowed to kill her. Gremory has gone missing, and Kimaris has disappeared in search of her. Everything Zagan loves and cherishes is at stake. An army of ten thousand resurrected heroes looms in the distance--it is time for an all-out battle between Zagan and Shere Khan. And most importantly, Nephy wants all of this resolved in just three days so she can still throw Zagan a surprise birthday party. Join the ever awkward Zagan as he is forced to protect those he loves in volume thirteen of An Archdemon's Dilemma: How to Love Your Elf Bride!

Zagan and Nephy's clumsy cohabitation continues!
