Common isekai stories typically follow a set formula. There's the sudden transfer to a different world, often accompanied by a truck-kun moment (where the character is hit by a truck and wakes up in another world). Then, there's the discovery of new powers or skills, making friends or allies, and usually a grand quest to save the new world or achieve something great.
Well, a common isekai novel usually has a few typical elements. For example, the protagonist is often transported from our normal world to a fantasy world, either by being reincarnated or some kind of magical accident. There's often a system in place that gives the protagonist special abilities or quests to complete. Also, there's usually a power - up journey where the main character gets stronger over time.
One common theme is the idea of starting anew. The protagonist often gets transported to a different world where they can leave behind their old problems or limitations. For example, in many isekai stories, a character who was a loser in their original world becomes a hero in the new one. Another theme is exploration. The new world in isekai fiction is full of unknowns, like strange creatures, new magic systems, and different cultures. Also, power - up is a big theme. The main character usually gains special abilities or powers during their adventures in the isekai world.
A big trope is the 'fish out of water' situation. The character from the real world has to adapt to the strange rules and customs of the isekai world. Also, there's the 'chosen one' trope. The protagonist is somehow destined to save the isekai world or fulfill a great prophecy. And let's not forget the 'gaining levels' or 'power progression' trope, where the character gets stronger as they complete tasks or defeat enemies.
One reason could be the marketing. Maybe it didn't get as much promotion as other popular isekai novels. Without proper marketing, it's hard for a book to reach a wide audience, even if it has good content.
Betrayal is a very common theme. Usually, the protagonist is betrayed in their original world or in the isekai world they are transported to, which then triggers their desire for revenge.
One common theme is the fish - out - of - water experience. The main character is suddenly in a new world and has to adapt, which often leads to interesting romantic encounters. For example, they might be confused by the different social norms regarding courtship in the isekai world. Another theme is the power of love to change destinies. In many novels, the character's love for someone else gives them the motivation to overcome obstacles in the new world.
Well, in a generic isekai novel, the idea of starting from scratch is quite common. The protagonist has to adapt to a new society with different rules, cultures and languages. For example, they might have to learn how to use magic if it exists in that world. Also, the concept of a 'chosen one' is often there. They are seen as the key to solving some big problems in the new world, like defeating an evil lord or saving the world from a great disaster.
Power. Usually, the main character, as a maou, has some form of great power, whether it's physical strength, magic, or strategic intelligence. This power is often used to overcome challenges in the new isekai world.
One common theme is the fish - out - of - water situation. The main character is transported to a new world, often with different cultures and social norms, and has to adapt while falling in love. Another theme is the power - up or growth. As they navigate the new world, they gain abilities which play into their romantic relationships. For example, in many novels, the female lead might start as an ordinary girl but become a powerful mage or something, and that affects how she is seen by her love interest.
