Are Yamato people fundamentally incapable of surviving without rice?
This seems to be a recurring theme in isekai series... The protagonist goes on a fuckin quest for rice and soy sauce.
Yeah okay, I'd be a bit peeved if I had to go without bread for a long time... but that is because bread is convenient. If I had some sort of suitable alternative like tasty leaves or something, I'd be fine. But this... this is ridiculous.
