Beginning already feels rushed and lackluster, but im probably biased because its just another magic academy underdog mc that face slaps everyone with his overpowered abilities every chapter.
Maybe showing his face to them is his calling card for the dead? A simple message of even if you make it out I will hunt you down now that you have seen my face. Or an act to demoralize the as they see a child. And if its a cursed bloodline that mean his parents and his children would have magic as well? Cause if it randomly happens that is not a bloodline at all. (Unless they pulling something like the ancestor of commoners had a cursed blood that sometimes appeared or something.)
