Kinda want the mc to be reincarnated/transmigrated but its fine if its not. Also I hope that the side characters also have a brain like if the mc does something that is incredibly unusual, the side characters call him out on it. Especially if is the kids parents. An example would be like if the kid casts a powerful complex spell that wipes out a small forest and acts as if nothing happens. I guess what I mean is I want the mc to be held responsible for his actions at a certain degree.
Superstars of Tomorrow. World setting is in the future, the character is transmigrated but as young adult. I think the side characters are not stupid, but MC himself is good at hiding it.
