I'll straighten out everything that's twisted! Survive this fantasy world using modern technology—not combat or crafting!

Kai Kazami, a chiropractor exhausted from working nonstop solo shifts at his clinic, is accidentally summoned to another world when a spell goes disastrously wrong. There, humans and demi-humans are locked in constant conflict in a world of swords and magic. ...But who cares about that!? What is that creature!? You look kind of like a bird, but with those muscles, how are you even flying!? Wait, hold on—let me touch them for a second!! No legendary weapons. No combat abilities. No convenient tools or overpowered cheat skills. All he has are the chiropractic techniques he’s honed over the years—and an undying love for muscles. Now, armed with nothing but his own two hands, it’s time to loosen up this entire fantasy world!
