Rereading again and can confirm the Hero of the South is a GigaChad.
The man was a beast. Even fighting one of the seven sages is tough as hell so for him to fight all 7 of them and kill 3 in the process is incredible.
there's this quote i once heard that feels apropos to this situation. i think it was something like "the mark of a great society is when old men plant trees in whose shade they know they will never sit." hero of the south knew he wouldn't defeat the demon king or even get to see the peaceful world he helped create, but he still took out those sages of destruction to make it easier for himmel. he truly was a chad
