Karate Master Isekai

After losing a fight with a runaway truck, a karateka is transmigrated to another world, one full of swords and sorcery straight out of fantasy books. The goddess who sent him there offers him a superpowered cheat skill to assist him in his upcoming heroics⸺but naturally, he turns her down. After all, he already possesses the only technique he needs: karate! No matter what manner of otherworldly foe he may face, be they a minotaur, a gigantic steelclad knight, or a wicked sorcerer, none of them will discourage him from walking his own path in the way of the empty hand!

The karateka lives by a seemingly simple maxim: “Don’t worry. Believe in karate.” But in a world of powerful magic and monsters, how far can karate really take you? Our hero’s faith in his martial art is put to its ultimate test in the face of Javid the Hexblade Hero, a planeswalker who’s eager to unleash his boundless magic upon the stratified society that never ceases to disappoint him. When Javid annihilates a monument to draw out the royalty, it seems like only the karateka might be capable of stopping him...but can skill alone defeat a man capable of felling an obelisk with a single spell? Will the karateka finally unlock his cheat skill to level the playing field? Or can the way of the empty hand overcome even the might of sorcery?

Now an adventurer alongside Princess Wilma, the karate master takes on any fight his guild gives him, including an all-out brawl against a hundred goblins and their gigantic champion. Not everyone appreciates the work he does, though—after he handles a slew of arrests, the Orc Mafia marks him for death! Seeking to make an example out of the karate master, the Mafia take one of his fellow adventurers hostage and force him to duel a towering, flame-clad ifrit in a crowded stadium to save her. Can the karateka thwart this fiery public execution? Or will our hero’s journey end in ashes?

After the karateka defeats the Orc Mafia’s summoner and his fearsome Ifrit, an assassin comes to claim his head: an elf warrior wielding a martial art known as High Elf Magic Jujutsu! And yet, it doesn’t seem like our hero’s would-be assassin is truly out for blood... Will the karate master survive and learn his foe’s true motivations? Or will he succumb to his nimble opponent’s joint locks and air blades in their clash of refined techniques?
