Maybe it's the plot twists. Most common isekai stories follow a predictable pattern. If this one has unexpected turns, like the protagonist not getting the usual overpowered abilities right away or having to face moral dilemmas that are not common in the genre, that would make it stand out.
The writing style could be what sets it apart. A lot of isekai novels have a rather basic style. But if this one uses more vivid descriptions, unique metaphors, and has a better flow, it can feel very different. For example, instead of just saying 'he entered the forest', it could describe the forest in great detail, the sounds, the smells, and the feeling of unease as the character steps in.
Well, it could be the character development. In some isekai novels, characters are just one - dimensional. But if this one has complex, evolving characters, that's a big plus. Also, the world - building might be more intricate than the common isekai. Instead of the typical medieval - like setting, it could have a blend of different eras or cultures.
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 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.
One unique aspect could be the way the protagonist is transported. Instead of the usual death - and - reincarnation or magic portal, it could be something really different like being pulled into a painting or a song. Another thing could be the world - building. If it has a really strange and unique world, not just the typical fantasy stuff, like a world made of living crystals or where emotions are physical entities.
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.
Reverse isekai novels are unique because they flip the typical isekai formula. Instead of a character from our world going to a fantasy world, it's the other way around. This creates interesting scenarios where characters from magical or otherworldly places have to adapt to our modern, often mundane world. For example, in 'The Devil is a Part - Timer!', the Devil King has to deal with getting a job at a fast - food joint in Tokyo.
In 'isekai maou shera novel', the way the protagonist interacts with the new world could be different. Instead of following the typical tropes, like quickly becoming a hero, the character might struggle in a more complex and unique way. They could have to deal with the cultural differences in the new world in a more in - depth manner, which is not always the case in other isekai novels.
One element could be the setting. For example, instead of the typical fantasy world, it could be set in a post - apocalyptic isekai world where the protagonist has to deal with both the new world's magic and the remnants of a destroyed civilization. Another aspect could be the protagonist's unique ability. Most isekai protagonists have common powers like magic or super strength, but if the protagonist has an ability that's not often seen, like the power to control time in a very limited and strange way, it would make the story less common. Also, the way the story deals with the concept of 'returning' can be different. In a common isekai, the protagonist may not think about returning at all, but if the whole plot revolves around the protagonist's struggle between staying in the new world and finding a way back to the old one, it would stand out.
The unique thing about a different love story is its deviation from the common love story tropes. It doesn't follow the usual boy - meets - girl, they - fall - in - love - immediately pattern.
The lyrics and the melody combination give it a distinct charm. The way the song expresses emotions is quite different from others.
