So if I'm understanding this story so far correctly, I'd venture to guess that heroes long ago in ancient times really deserved the name, cause those times actually involved great peril and a need for chosen champions to be given all the support they need to fight against w.e was happening back then. And now, with, to an extent, the perils being over, or not as big of a problem like some Demon King running rampart waging war on humanity or anything like a monster tide, came the easy times, and easy times created weak men, which will create hard times, and in this time being a hero stop being about acting like one and instead it turned into some prestigeous position for political reasons and those who become so are corrupt or they become corrupt after reaching that status, I also bet that the heroes existing now can't even hold a candle to the heroes that existed back in the day in this world. But mainly that, they are heroes in name only and the position, status, and influence is riddled with corruption and corrupt people attaining that title of hero instead of people who actually deserve it, and our MC here is probably the first in a long time to show up to actually attain the title and own it.
