Imagine that you were Greed. You were given the gift of being loved by the spirits and being able to use all their powers to their fullest potential. In that same world, the vast majority of the population are only talented in one or two spirit powers.
Demons are the only beings in that world that are capable to wield immense power. Now later on you become a Hero. Some one that the Goddess herself has chosen to fight against these demons.
You alone have enormous power. Power to rival the strongest countries. Power that is equivalent to the elementary forces of mother nature.
People will fear you. Despise you. Want to use you. Control you.
Very few will want to be standing next to someone who can end the world if they so choose.
You will be alone. Yet what if one day, after seeing people's fear and worship gazes, you see someone who makes your heart beat in the first time in forever? That they make you smile. That they make the pain that you went through all worth it?
If you find that special someone you would want to protect them. To guard them against your enemies. You would do everything in your power to make them smile at you because to you they are a miracle. They are your liferaft amidst the stormy waves
What I like most about this novel so far is that we learn that he once had a dream about being a hero. However since he had been an assassin who murdered heroes amongst other things, he felt that he no longer had the right to relive his life as a hero. It is interesting that while he may not see himself as a hero, many flock to his side (dispite trying to get rid of them... lol)
