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.
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.
Isekai Quartet indeed has a manga. It offers a different perspective and sometimes delves deeper into the story compared to the anime. The manga can be a great companion to the animated version for fans wanting more of the Isekai Quartet world.
This is not a valid or advisable aspiration. Comics can sometimes depict extreme or unethical things, but that doesn't mean it's something to strive for. Look for careers that contribute positively to society instead.
I'd recommend checking out online manga libraries such as Comixology or Crunchyroll Manga. They often have a good selection of isekai titles. Also, some local libraries might have physical or digital copies you can access.
I wouldn't recommend pursuing such a path. Becoming involved in pornographic content is not a positive or ethical choice and can have serious negative impacts on your life and reputation.
Isekai manga is a genre where the main character gets transported to another world. It's different from others because of the focus on this world-jumping aspect and the adventures that follow.
For must-read isekai manga, 'Sword Art Online' is a great choice. It combines action, adventure, and a touch of romance. The virtual world it creates is both exciting and immersive.
