The phrase refers to a narrative trope commonly found within Japanese light novels and web novels (often adapted into manga or anime). It describes a scenario where the protagonist is reincarnated or transported into the world of an otome game (a dating simulation game typically targeted at a female audience), but not as the main character or a love interest. Instead, the protagonist finds themself in the role of a “mob character” a minor, often insignificant, background figure who is not crucial to the main storyline.
This trope offers several narrative advantages. It allows for exploration of the game world from a unique perspective, highlighting the complexities and nuances often overlooked when focusing solely on the central characters and romantic relationships. The perceived insignificance of the “mob” role can provide a canvas for unexpected actions and consequences, as the protagonists actions, even small ones, can disrupt the intended narrative flow of the game. Historically, this framework provides a contrast to the traditional power fantasy of being the central figure, offering a more self-aware and sometimes satirical take on the isekai (another world) genre.
