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?

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.

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.

Traveling to another world, either by accident, magic summoning, death, cruel twist of fate, on a research assignment, or just on vacation, means dealing with a whole lot of change all at once. In this compilation, the authors of the SAKKA KEIHAN writing circle explore the ins and outs of what to expect when you’ve been transported to another plane of existence. Six different short stories cover the authors’ ruminations on how to get by in these other worlds, whether you’re headed over voluntarily or finding yourself just trying to survive. You’ll probably want to bring a towel; things are going to get slimy. Don’t think it’ll save you from a fireball, however.

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.

Shinichi Sotoyama might just be the world's most average high schooler. That is, until he finds himself summoned by the Blue Demon King to a fantasy world-just like his favorite RPG games! Except this Demon King is pathetically begging at his feet, lamenting the arrival of some "heroes"...who apparently, have infinite lives and respawn over and over again?! Unlike his hysterical summoner, Shinichi coolly takes on the challenge of fending off these pesky heroes, literally shaking hands with the devil. But the demon clan is about to find out that his twisted mind is darker than the worst of them!
