I think the uniqueness of 'jinsei reset button light novel' lies in its exploration of the 'what - ifs' in life. While other light novels often deal with the present situation of the characters in a new or existing world, this one gives the protagonist the power to go back and change things. This can lead to a different kind of character growth compared to traditional light novels. For instance, the protagonist may not just grow stronger physically or gain new skills like in some action - based light novels, but rather grow in terms of wisdom and understanding of life's choices. It also has the potential to create a more immersive world - building as the resetting of life could change the world around the character in various ways, which is not a common trope in light novels.

Its use of Japanese mythology. Tokyo Ravens light novel stands out because it dives deep into Japanese mythology. This gives it a rich and unique flavor compared to other light novels that might not explore such cultural aspects.
