Although it's more of a comeback manga than an isekai, it follows many of the same themes and patterns. One day, a door suddenly opens on Earth, monsters are summoned, and certain people are transported to another world. Park Soo-ho is taken to a jungle planet where huge animals live and there is no human civilization at all. He survived there for hundreds of years, but only ten years had passed when he was suddenly teleported home.

It starts off as a typical hunter fantasy, but becomes more complex as you explore planets that are actually connected to Earth. Humans can use magic and science to seal and monitor the dungeons that appear, and will eventually be able to communicate with and visit other planets. These developments help set this comic apart from other similar comics.

Rather than one person being kicked out, the entire city of South Korea is transported to another dimension where it becomes part of the board game. The main character, Choi Yul, randomly receives extremely powerful items, through which he can obtain information about all scenarios that appear. Unfortunately, since you also steal rewards from other players, you have no choice but to become a public enemy that will lead them to success.

Like many other isekai, this manga is filled with fantasy archetypes and concepts, mostly magic items, demons, and technology. The sci-fi nature doesn't appear until after the first 40 chapters, when the city begins to integrate modern technology and magical resources to strengthen itself enough to survive a nuclear-level threat.

This cartoon stands out because it is both an otherworldly and a reverse otherworldly world. The protagonist is reborn as Leon Dragonia in another world and eventually becomes the King of Lionheart, blessed by the gods. When that world becomes overrun with monsters, he eventually returns to Earth through a door that usually releases the monsters. Leon soon becomes a world superpower due to his connection to the pantheon of gods.

Although the story is set in modern times, it still has some sci-fi elements. Because portals connect different dimensions, enemies aren't always monsters like orcs or goblins. Robot is one of the main antagonists of the short story and later becomes a supporting character, manipulating the media and stock market to support Leon.

Androids and drones are just some of the obstacles Jaehwan must overcome, and they will definitely appear again in later chapters, even if they only appear for brief moments at a time.

In isekai manga, it is common to get trapped in a novel. In this story, Hajin Kim receives a strange email and becomes trapped in the world of her own web novel. Now he must compete with the cadets to become a hero in the body of a background character. It should be a simple task for a writer, but an unknown editor is changing his story, causing new events and developments.

This comic is a great example of urban fantasy that depicts the integration of magic into modern society. The story takes place in the island city of CUBE, a high-tech metropolis that supports an academy of the same name to produce heroes. The Academy is where most technological achievements can be found, including creating holograms, simulations, and enhanced weapons.

One popular virtual technology present in many comics is the full-dive VR capsule, which allows people to experience the game as if it were real life. Jin Tae-kyung becomes trapped in a virtual world after using a game capsule as a bed. He wakes up in the martial arts world and becomes a young man from a prestigious family. The only way to log out is to complete certain objectives, and if he dies, his actual body dies too.

Since most of this story actually takes place in Wulin, there isn't much of a scientific or technical aspect to it other than the game system. However, there is a part where Jin Tae-kyung returns to the real world, so we can see more sci-fi elements. The comic is actually set in dungeons and hunters, which is an interesting contrast to the world of Wulin games.

What happens when science, martial arts, and magic all come together? Trinity Wonder is a cartoon that answers that question. A company's experiment creates a connection to another dimension, and martial artist Kang Woo-jin and wizard Emily come to Earth. With no way to return home, the pair must trust the company's owner, Sylvia, to repair the machine that connects the world. But there is more to the problem than meets the eye.

The comic does a good job of balancing three separate themes without complicating the story, with each theme having its own role to play. The setting is a future Earth, the main antagonist is the leader of a demonic sect, and the final boss is a giant dragon. Everything is seamlessly connected so you can stay focused on the entertaining story and fantastic action scenes.
