To enter Heaven you do not necessarily have to believe in God or follow all his rules. When a person die they will be judged and you are let into Heaven if you pass one of their requirements, if not you will be send back to Earth to start a new life. Dying a heroic death is one of those requirement that would get you into Heaven. That is what one human learned when he died saving a child from being run over.

He was let into Heaven but he wasn't happy. Heaven is very strict, something as simple as a lie can get you into trouble and you'll have to go through a very hard training. You see, when you enter Heaven you enter as an Angel. And as an Angel you have to be trained to protect every living thing on Earth from the Demons.

You will be taught that Demons are evil and needs to be destroyed or they will corrupt you and everything they touch. Once an Angel is corrupted they are stripped of their wings and their soul is sent back to Earth. A soul that is too corrupted will risk being turned into a Demon and restarting a soul's life would cleanse it.

If you fail even one of the training you will be sent back to Earth to start a new life.

Training is hard but not impossible and when you pass all the training you will be sent to Earth to watch over the souls of every living thing.

There are more souls than Angels so they have to work overtime to keep the balance of good and evil from tipping over to the evil side.

So here he is, on Earth watching over the souls that are going on their everyday lives.

He has short, messy black hair, brown eyes, wearing the standard white uniform robe that all Angel wears and his pure white wings sit comfortable on his back. He no longer need to wear glasses and he is also the fittest he has ever been thanks to the training he was put through.

He has never left his country when he was alive and now that he is an Angel he would see as much as he can without leaving where he is stationed.

His job is to make sure that no Demons try to corrupt any of the souls but it also mean he is unable to stop murders, robbery or any crimes committed by a soul, sure he can try to use his powers to reach out to the goodness in one's soul but that doesn't always work. All he can do for the criminals and their victims is to get their soul to be reborn before a demon can get their hands on it and place a healing spell on the survivors so that they may heal from the traumatic event.
