Renegade in a Zombieland RAZ

In a world where people with powers known as demigods existed, there were academies to raise such children. These academies were called the Pantheons. Hades, one of the strongest demigods and a playboy ended up getting on the bad side of his Pantheon's 7 beauties who each represented one of the seven deadly sins.
One day while on the toilet, he is killed by a large attack from the 7 beauties.
He didnt even notice that it was an attack and thought there was just a pretty color show, until he leaves the toilet and finds out that he is in a world filled with zombies. Now he is trying to find a way back home, while making a few messes here and there in the new world.
