@Balhok No, it's gotta match up. The Cake MC became Mary Antoinette because of the infamous "let them eat cake line". The sushi chef has to reincarnate as a historical figure with an extremely stretched link to something about fish.
This is promising, I want to see what will happen.
I'm interested in the implications of her setting, if she tries to change history and succeeds, will this new timeline be considered a parallel world?
Would this then fall into the isekai category?
Edit: Also, in this scenario. Would she still know how to speak in Japanese? If by chance, she meets a Japanese person, would she just knows how to converse with them?
