Suimei and two of his best friends find themselves mysteriously summoned to another world. There's a cute princess, magic galore, a Demon Lord that needs to be defeated, and a world that needs to be saved--the works! Too bad Suimei isn't interested. His friends are all too ready to play the parts of heroes, but Suimei just wants to get home. He has an advantage as a magician... but he's in for a rude awakening when he finds out what actually passes for magic in these parts.

Suimei finally strikes out on his own, but what is life going to be like for a modern magician in an old-fashioned Adventurer's Guild? And what of Reiji, Mizuki, and Titania? How will any of them handle their first encounter with a real demon?

Suimei has finally figured out a way to get home, but it’s too soon to celebrate. Suimei’s return to his own world is less of a homecoming and more of a pit stop on a much larger and much, much more dangerous journey. Suimei needs to amass as many allies and resources as he can if he has a prayer of defeating his nemesis once and for all... But that’s going to get a little tricky if he’s babysitting the entire time. The girls are in for a surprise in this world where science is king!

Suimei finally has his base set up, new housemate and all, and is primed to devote himself to his research in trying to find a way back home. But things are never that simple for our hard-luck anti-hero from another world. There's still a shadow on the loose in the city and an unfinished duel with a real hero to settle, but to make matters worse, someone new seems to have taken an interest in Suimei and his affairs. Meanwhile, Reiji and the others continue their own quest to save the world, which may take an unexpected turn.

Miyuki's classmate Shizuku Kitayama is on her way to study abroad. For magicians, this is normally impossible, since allowing the genes of someone who can use magic outside their home country's borders is tantamount to giving up national secrets. But it's allowed to happen in one case-exchange programs. And that's how Angelina has arrived in Japan from the USNA to study at First High. But it seems she's a part of something much bigger than a simple cultural exchange!

Once upon a time, in the not too distant past, a holy maiden was summoned. Not just any holy maiden—one hailing from modern Japan. But this story is not her story. This is the tale of the humble accountant, Kondou, who accompanied her and his trials and woes as he accounts in a new world... But no tale is complete without a love interest. And who better to play that role than the handsome knight captain Aresh? Will he begin a personal quest to save said bean counter—who toils around the clock—or is Kondou doomed to be married to his work evermore...?!

I had to accept that I wasn’t just Arthur Leywin anymore, and that I could no longer be limited by the circumstances of my birth. If I was going to escape, if I was going to go toe-to-toe with the most powerful beings in this world, I needed to push myself to my utmost limit...and then I needed to push even further. After nearly dying as a victim of his own strength, Arthur Leywin wakes to find himself far from the continent where he was born for the second time. Alone, broken, and with no way to tell his family he’s alive, Arthur must rebuild his strength to survive. As he ascends through an ancient dungeon filled with hostile beasts and devious trials, he discovers an ancient, absolute power - a power that will either ruin him or take him to new heights. But the dungeon won’t give up its knowledge easily. Before he can plunder its depths, Arthur must learn to untangle the threads of fate. He must band together with the unlikeliest of allies if he hopes to escape with his life.
