Karate Master Isekai

After losing a fight with a runaway truck, a karateka (karate practitioner) 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! ___ **Note:** The title, Karate Baka Isekai, is a parody of the manga [Karate Master (Karate Baka Ichidai)](https://mangadex.org/title/165763bd-5346-4d64-b957-383d97aa23ae). It doesn't mean he's an idiot. * Original WN: [Kakuyomu](https://kakuyomu.jp/works/1177354054884503755)
