I don't watch Oriental cartoons but I used to love watching 80s John Hughes teenage HS films in the early 2010s and I came to the conclusion that if incel-type characters were ever featured in these films... they were the loner kid somewhere out-of-focus in the background. Not the camera friendly, mainstream approved, TV ugly 'weirdo loner' who is an actual (side) character in the plot of the story.
Our stories will not be told by outsiders. Period.
And if indeed they do start making 'serious' incel themed movies or comics - then they will not represent us entirely accurately because the script writers, producers and directors don't viscerally understand what it is like. Or would want to represent it without condemning it, framing it. They will never go deeper than the outside, inherently progressive perspective.
This is life as a marginalized minority. We are living it.
Incels will have to start creating their own art to tell their stories. It already happens via memes and innovative, viral neologisms that are spreading to the mainstream - but there will also have to be longer form, higher production value (true effort posting) short stories, novels and movies that will exist outside of the mainstream framing of 'reality'. Houellebecq told the proto-incel story for his generation, the boomer/genX crowd, it is unclear who is doing it for the millennial/zoomer cohorts who grew up online post 2000.
