I'm not entirely sure as there are many novels with this kind of theme. Generally, in 'isekai' (another world) type novels with cheat skills, the protagonist is often transported to a different world and has some special ability or skill that gives them an advantage, like super strength or magic powers, which they use to navigate this new world.
I don't know specifically since there are many novels with this title or similar concepts. But usually, there is a protagonist who is the one with the cheat skill and gets transported to the isekai world. There might also be side characters like friends or mentors that the protagonist meets in the new world.
In 'isekai cheat skill light novel', it gives a sense of wish - fulfillment. People often daydream about having extraordinary abilities in a different world. The novels let them live vicariously through the characters. Also, the unique skills often lead to unexpected and exciting plot twists. For example, a character with the ability to control time can change the course of battles or relationships in the isekai world, which keeps the readers hooked.
One popular one is 'That Time I Got Reincarnated as a Slime'. In this light novel, the protagonist gains unique skills in his isekai adventure. Another is 'Overlord', where the main character has overpowered abilities. There's also 'No Game No Life' which features the siblings with incredible skills in a game - like isekai world.
One characteristic is the overpowered abilities of the protagonist. They usually have a skill or ability that is far beyond normal, like instant magic mastery or superhuman strength. Another is the exploration of a new world. It could be a medieval - like fantasy world or a high - tech sci - fi world. Also, there's often a sense of the protagonist being an outsider who has to adapt and use their cheat skill to thrive.
The 'isekai de cheat skill otakudesu' light novel is probably centered around the concept of an otaku finding themselves in an isekai. The 'cheat skill' is a crucial element. It could be something like super strength, the ability to instantly learn magic, or having an all - seeing eye. This skill would then drive the plot as the character uses it to overcome difficulties in the new world. They might meet different races, discover ancient secrets, and ultimately strive to reach a certain goal, perhaps to return to their original world or to become the most powerful in the isekai.
I'm not sure specifically as I haven't read the light novel in detail. But typically in such isekai light novels, there is a protagonist who is the otaku with the cheat skill. There could also be side characters like a female lead who might be a princess or a powerful mage in the isekai world, and a mentor - like figure who helps the protagonist understand and use their cheat skill better.
Yes, it is quite popular. Isekai, which means 'another world' in Japanese, has been a booming genre. And the concept of having a cheat skill in this other world makes for very exciting and engaging stories.

Well, 'tondemo skill isekai novel' might follow the common isekai tropes. The main character could use their 'tondemo skill' to navigate the challenges of the isekai world. For example, they might use it to fight monsters, make friends with strange creatures, or solve the mysteries of this new realm. Since it's an isekai novel, there's also a good chance that the story involves the character's growth and adaptation to this different world with the help of their unique skill.
Often, there is a big contrast between the skills from the original world and the challenges in the isekai world. For example, in 'Overlord', the protagonist's gaming skills are put to the test in a much more complex and unpredictable real - like fantasy world. The skills might seem overpowered at first but as the story progresses, new challenges emerge that require creative use of those skills.
