Oh! Thatās right! Howās I forget about the human rule! Damn! lol
Ok, weāll do Coco then. Thatās another good one!
Miguel's great-grandfather was a wizard. He left the family to do...I dunno, wizard things, but never came back. Angry at the abandonment, his wife Imelda put a ban on magic in the Rivera household, and none of the subsequent generations have been trained in any way. This has led to a comedic number of accidental explosions, Transfigurations and other mishaps. (Miguel's cousin Abel still has feathers that they never figured out how to get rid of.)
Eventually, Miguel comes to believe that his ancestor was a famous wizard named Ernesto de la Cruz. He steals Ernesto's old wand (which turns out to have an anti-theft curse on it) and runs away to Hogwarts to learn magic by himself. While there, he befriends HƩctor, who is one of the school's ghosts.
I'm not sure about Miguel's house. Artsy types are generally Ravenclaw, but he's also sneaky and a little morally gray (see "cursed for grave-robbing"), so he could be the rare Good Slytherin.
