Having come a long way since his disinheritance, Arcus is introduced to his very own servant: Noah Ingvayne, the “winter wunderkind,” brought in not only to aid with Arcus’s invention, but also to help him further his magic and combat studies. Speaking of the aethometer, it’s time to introduce it to the Guildmaster... Meanwhile, Lecia’s father takes her to a party thrown by one Cau Gaston as preparation to take up the mantle of heir to the Raytheft house. Troubling rumors surround the party’s host, but surely Lecia is too young to have to worry about them...right? With dark dealings threatening his sister’s safety, it’s up to Arcus to face one of the most powerful nobles in the land.

Cursed with a naturally low supply of aether, Arcus Raytheft is disinherited and shunned by his family. Things start to change when he experiences another man’s life through a dream—a dream that shows him marvelous technological wonders that don’t exist in his world. Armed with this new knowledge, Arcus sets about showing his parents that they were wrong about him. Surely an arsenal of mind-blowing spells will be enough to convince them you don’t need aether to succeed?

Arcus is still leveraging his otherworldly scientific knowledge to improve his magic. On hearing news that Lecia, his beloved sister, had been kidnapped, Arcus set off to rescue her, only to be thrown into the Holy Tower. There, he runs into an old friend...or rather, enemy. They say no one can escape the Tower, but if he doesn’t, there’s no telling what might happen to Lecia...

The Raythefts are an old, minor noble house defined by magical talent and martial service. When six-year-old Arcus Raytheft, firstborn son to the family, proves disappointingly inept at magic, he is stripped of his inheritance and written off by his parents. His adoptive sister Lecia still adores him, but as the new heir, she is forbidden to interact with anyone who might drag her down. But when one inheritance is lost, fate arranges another: Arcus remembers another life, in a world where science prevails and magic belongs to the realm of fiction. Suddenly endowed with the life experience of a grown man and pressed to find a purpose as his family turns against him, Arcus resolves to find a way to break the laws of magic and Raytheft tradition over his knee!

Drawing on knowledge gained from his dream of a second life in another world, Arcus created the aethometer: a device that measures the essence of all magic. Now, he is finally ready to present his revolutionary invention to his nation’s premier magicians and military leaders. With the circle of trust containing the device’s earthshaking implications cast wider, how will the aethometer move to change Arcus’ fate and the fate of the world itself? Others within the gentry are keeping a close eye on Arcus after his decisive actions on the marquess’ estate. Whether they are friend or foe remains to be seen—but subtle machinations rarely remain so for long when Arcus is involved.

After a war of twists and turns and a brief convalescence, Arcus is finally ready to return to Lainur’s capital. There he’ll meet Ceylan’s father, King Crosellode, and be rewarded for his valiant efforts—although he’s not the only one due for an audience with the king. While rumors about Arcus continue to spread, the Empire evaluates its own part in the war. Will the nation remain a sleeping lion, or begin plotting its next move? And what of the cryptic quest to seek out an emerald on Chain’s behalf, which Arcus received in a dream? Without any clues as to what it might mean, he hardly knows where to begin. But one thing’s for sure: he’s going to be busy for a long while yet.

It’s hard being a modern magician in another world! While his best friend Reiji sets off on a quest to subjugate the Demon Lord, Suimei is fighting off palace intrigue and departing on a journey of his own—one he hopes will help him find a way back home. First stop? The local branch of the adventurer’s guild where new challenges and allies await. But when he’s put to the test, can he rise to the occasion without blowing his cover?

Arcus came to Rustinell to top up on supplies; that’s still on his to-do list, but he has averted a plot to kill the crown prince of Lainur! The prince declares war on the treasonous Porque Nadar—and orders Arcus to fight by his side. Arcus never meant to get involved, but a monarch’s word is law. After all he’s been through, Arcus might be prepared for open warfare; regardless, there’s no place more dangerous to stand than in the shadow of the boy who would be king. Especially when you consider the royal family’s track record with close friends...

Want to learn about databases without the tedium? With its unique combination of Japanese-style comics and serious educational content, The Manga Guide to Databases is just the book for you. Princess Ruruna is stressed out. With the king and queen away, she has to manage the Kingdom of Kod's humongous fruit-selling empire. Overseas departments, scads of inventory, conflicting prices, and so many customers! It's all such a confusing mess. But a mysterious book and a helpful fairy promise to solve her organizational problems—with the practical magic of databases. In The Manga Guide to Databases, Tico the fairy teaches the Princess how to simplify her data management. We follow along as they design a relational database, understand the entity-relationship model, perform basic database operations, and delve into more advanced topics. Once the Princess is familiar with transactions and basic SQL statements, she can keep her data timely and accurate for the entire kingdom. Finally, Tico explains ways to make the database more efficient and secure, and they discuss methods for concurrency and replication. Examples and exercises (with answer keys) help you learn, and an appendix of frequently used SQL statements gives the tools you need to create and maintain full-featured databases. (Of course, it wouldn't be a royal kingdom without some drama, so read on to find out who gets the girl—the arrogant prince or the humble servant.) This EduManga book is a translation of a bestselling series in Japan, co-published with Ohmsha, Ltd., of Tokyo, Japan.
