When the author describes a character’s appearance way too late and you have to quickly redesign the image you already have for them in your head:
This is why if you want people to know your character has long raven-black hair with red streaks and eyes like limpid tears, you need to make sure you say so in your first paragraph. Christ. Imagine someone thinking your character’s a prep.
“It wasn’t something I did arbitrarily. When I read Takahashi-sensei’s source material, I thought, ‘This character has that kind of personality so they might do this kind of thing.’ For example: Joey is the hot-blooded ‘big bro’ character -> He might like martial arts -> I suppose he likes wrestling -> I bet he likes Inoki -> The chin! That’s how it went.” — Takahiro Kagami, 2012.
