The Black Cat Hero and the Minister of Sloth — Reforming the World via Remote Work to Protect My Peaceful Slumber
"This world is a legacy system running on an unpatched OS. I'm just here to install the stability updates."
When Kazuya, a former systems engineer and corporate slave, was summoned to another world along with his entire house, he didn't ask for a legendary sword. He asked for Fiber-Optic Internet.
Armed with the collective wisdom of the entire world via the Internet, there is now virtually nothing he doesn't know. He has zero interest in "grand adventures." He’d rather stay inside his magically-transported home, drink ice-cold cola, and solve the Kingdom’s greatest crises via remote work. By treating every disaster—from collapsing infrastructure to "ancient curses"—as a series of logical bugs, he optimizes a world that relies far too much on fickle magic using modern systems thinking.
While he "works" from the comfort of his sofa, his black cat Tama—who is secretly the Legendary Savior, Tarmane—is busy "deleting" any hardware threats (monsters) that dare disturb her owner’s Wi-Fi signal.
The people call him a "Transcendent Sage." The Knights call his instructions "Divine Logic." In reality, he’s just a lazy optimizer who knows that in any world, information is the ultimate weapon.
An intellectual Isekai comedy where the greatest miracles aren't performed with wands, but with a perfectly executed patch.

**Note from the Author:**
This is the official English version of an original Japanese web novel, currently on going in Japan. While the English release is currently several dozen chapters behind the Japanese original, new episodes will be published here sequentially as the translation is finalized.
If you're tired of mindless action and want a "Rational Isekai" where problems are solved through logic, engineering, and data-driven strategy, this story is for you. Experience the intellectual catharsis of a modern engineer "debugging" a fantasy world—all from the comfort of his sofa.
Updates will be frequent as I work to catch up with the latest Japanese release!
