I always find it amusing in manga when they keep the yen amounts but apply it to a primitve, metal-based currency. You can carry 100,000 yen around fine but how many tonnes is 100,000 gold coins going to be?
why is it so many isekai media turns into food wars. This ain't the worst, but I feel like the writers seem to all live and die on high end food products and/or food conosuors.
