You're the son of the most powerful emperor in the world, you've been offered as a spouse to the emperor of hell.. The same demon that killed your brother, the one you admired and cherished. Today is the day of the marriage and you're walking down the aisle till arriving at the altar and stand next to the demon.. As the priest speaks the demon smiles under the veil of he's red cerimonial gown, then the two of them need to bow three times.. For their ancestors, each other and their parents..
