The 'isekai guns light novel' often has a sense of adventure. The main character, being in a new world, has to explore and survive. Guns can be a tool for that. They can also be a source of mystery. Sometimes, the guns may not work as expected in the new world due to different rules of magic or physics. This forces the character to adapt and find new ways to use the guns or other means of defense and offense. Also, these novels usually have a lot of world - building. The new world needs to be described in detail, and the role of guns within that world is an important part of the overall setting.
The unique feature is the combination of modern weapon concepts (guns) with a fantasy isekai setting. It creates a contrast between the familiar and the otherworldly. For example, in 'GATE: Thus the JSDF Fought There!', the JSDF's guns are a huge advantage in a world of swords and magic. This can lead to interesting power dynamics and plot developments.
There is also 'So I'm a Spider, So What?'. While it may not be as gun - heavy as the others, it does have an isekai theme. In the story, the main character, a spider, has to deal with various threats in the new world. There are some instances where gun - like magical attacks or devices are involved, making it an interesting addition to the isekai light novel genre.
One popular 'isekai with guns' light novel is 'GATE: Thus the JSDF Fought There!'. It features modern military elements, including guns, being introduced to a fantasy world. Another is 'So I'm a Spider, So What?'. The protagonist uses her wits and some rather unique abilities which can be related to a form of 'gun - like' strategic thinking in the isekai world. There's also 'Overlord', where the main character has access to various items and powers that can be seen as analogous to guns in terms of combat dominance in the new world he's transported to.
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.
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.
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 example, the answer to the question about the manga characters of the big gun in the DNF might vary according to personal preference. However, if you like games like Dungeon Fighter Online (DnD), you might be interested in the following characters:
