@Panino But the manga also readily ignores a lot of problems she might run into. Like, where's she getting all the free labor to chop those farms for mushrooms? To clear that part of the forest and keep it cleared? You telling me those farmers don't have enough work? And even if you have that covered, where do you get all the mushrooms in the first place? Getting a patch like that sounds to me like it'd take years and good fortune (again, bad weather, parasites, etc can easily ruin your crops even when you do everything right); it's not like you can put 1 mushroom somewhere and if the conditions are good a year later you have a forest of the freaking things ... or maybe I'm wrong about that. But we cultivated some mushrooms for a while (field mushrooms; it was more "for fun") and it certainly wasn't like this ^^
@Aichan A lot of that is romantized and idealized though. It's true you got those crazy nutcases where people kill themselves just to show their loyalty and so on, but specifically in the Sengoku period you also have everyone betray everyone else left and right, violating agreements and alliances whenever it suited them, going against established codes of conducts, and just generally being backstabbing opportunists. Personally I'd have a hard time coming up with a war/wars that involves
less "honorable" protagonists than the Sengoku period in terms of pure loyalty to the sides chosen.
Doesn't mean it was a good idea to "besmirch someone's honor", but let's be honest, they were as much about power and survival as people always are, overall.
