In an isekai novel like 'ore dake fuguu skill no isekai novel', the special skill of the main character is likely what makes it stand out. In many isekai stories, the skill gives the protagonist an edge in a strange new world. It could be a combat - related skill, like super strength or the ability to use powerful magic. Or it could be a more unusual skill, such as the ability to communicate with animals or manipulate time. This unique skill then drives the plot forward as the character has to learn to use it effectively, face challenges related to it, and often, keep it a secret from those who might misuse it. So, if this novel has a really creative and well - developed skill for its protagonist, it would be very special indeed.
