In the blink of an eye, thirty thousand bewildered Japanese gamers are whisked from their everyday lives into the world of the popular MMORPG, Elder Tale, after the game's latest update—unable to log out. Among them is the socially awkward college student Shiroe, whose confusion and shock lasts only a moment as, a veteran of the game, he immediately sets out to explore the limits of his new reality. Shiroe must learn to live in this new world, leading others and negotiating with the NPC natives in order to bring stability to the virtual city of Akihabara. He is joined by his unfortunate friend Naotsugu, having logged in for the first time in years only to find himself trapped, and Akatsuki, a petite but fierce assassin who labels Shiroe as her master. A tale of fantasy, adventure, and politics, Log Horizon explores the elements of gaming through the eyes of a master strategist who attempts to make the best of a puzzling situation.

For young witches everywhere, the world-renowned witch Shiny Chariot reigns as the most revered and celebrated role model. But as the girls age, so do their opinions of her—now just the mention of Chariot would get a witch labeled a child. However, undeterred in her blind admiration for Chariot, ordinary girl Atsuko Kagari enrolls into Luna Nova Magical Academy, hoping to someday become just as mesmerizing as her idol. However, the witch academy isn't all the fun and games Atsuko thought it would be: boring lectures, strict teachers, and students who mock Chariot plague the campus. Coupled with her own ineptness in magic, she's seen as little more than a rebel student. But when a chance finally presents itself to prove herself to her peers and teachers, she takes it, and now it's up to her to stop a rampaging dragon before it flattens the entire academy.
