For me, 'That Time I Got Reincarnated as a Slime' stands out. The world-building and plot development are really engaging. Also, the characters have a lot of depth.
Isekai manhwa refers to Korean comics where characters find themselves in otherworldly or parallel dimensions. It's a popular genre that offers exciting and imaginative storylines. Sometimes the characters gain special powers or have to overcome various challenges in these strange new worlds.
Isekai cooking manhwa stands out because it takes the familiar concept of cooking and places it in an otherworldly setting. The storylines often involve the protagonist using their cooking skills to solve problems or make friends. The detailed illustrations of the cooking processes and the imaginative food creations are what make it special.
No, they're not the same. Manga comes from Japan and has its own unique style and storytelling techniques. Manhwa is from Korea and has distinct characteristics too.
Well, it's a bit hard to pinpoint exactly which was the very first one. But some early examples could include 'El-Hazard: The Magnificent World', which had elements of the isekai genre.
