The Deadly Seven - Devil Dance

Once upon a time seven warrior entered to the homeland of a god to steal it's power. The god did catch them and punished them according to their sins. They got the power, but as a curse, that power is controlled by the demons of their sins. They have inhuman abilities, stronger body, great life-force, but has a short lifespan in human-form, and all the power and immortality but uncontrollable demon-self in demon-form. If they want the whole thing, they have to collect the other parts from the others.

The story is about - like the title suggests - seven people who fight against every other creature, each other, but mostly themselves. Their adventures are full of humor and irony, but sometimes grief and sadness. It's a fight for their future in both inside and outside. Hardships bring them closer or pull them apart.
The world of the story is a place where the three main religions of our world don't exist but gods do. The huge events of history went another way sometimes.
