"Relagh you are to go to earth to save the humans," said god.
" yes, I will," said Relagh a war angel
so as he descended to fight the demon's army he left behind his only son, Percy, who was half-demon and half-angel.
so the council of angels decided that Percy was to be trained in the way of the angels, as a result of that decision Percy was sent to the angel military school, where he faced a lot of problems due to the fact he was half-demon half-angel.
Will he discover why his father sided with the demon?
