Sushi is just fish on top of rice ... I mean the basis of it isn't wrong but the pro sushi chefs around the world would balk at the idea of just simply saying that you can just put fish on top of rice. Supposedly sushi chefs go through years to master the rice. They say the rice is the most important part even, because if you can't get the right ratio of vinegar, sugar, salt and the proper timing and technique for it, then the sushi will taste mediocre at best. So, no. You can't just fucking slap raw fish on top of rice and say you got sushi down and it's passable as sushi.
Anyways, looks like the prince and princess are both gunning for Fran. That's interesting lol. And it seems like the mangaka is trying to make that old royal advisor looking guy, Selido, seem like the one who's been putting the hits on the prince and princess.
