Y'all don't seem to realize this is a flashback chapter. Bonito, the one that got eaten, is the first fish she ever ate in Chapter 1. And that prophet kid's altered design has been there since Chapter 1 as well.
@Radicool21
not just the recipes, nakajima was also wandering around with Era's friends all the time, but he was the only one who never said a word within the group. and just stayed in the background
Era woudnt go to his funeral because he wasn't friends with her like Bonito was (shown by him stealing her bra), she wouldn't eat her first fish and develop her guilty hunger
