Having finally dealt with Shere Khan, a party is held to celebrate both the victory and Zagan’s birthday. Spirits are high all around when Gremory, who has been starved of love power due to her mission, declares the start of the Kianoides love power general meeting. Participants are dragged in, willingly or otherwise, and must recount love stories both recent and old to provide the granny with her requisite dose of sugar. Prepare for the most densely packed volume of sweetness ever to be published for this series to date!

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.

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.

After accepting Lilith's request for a larger bath, Zagan begins the construction of a grand bath in his castle to reward the services of his subordinates and provide a place of relaxation for Nephy and the other girls. Life in the castle is as peaceful and noisy as ever. However, Bifrons' evil schemes are advancing toward them, and the mysteries of what Alshiera has been fighting against for so long slowly begin to unravel.

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!

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...
