Abyssal Demon 'Aston' was an extremely ambitious devil.
He had spent hundreds of years meticulously planning and taking advantage of every opportunity to prove himself. Eventually, he pushed aside his superior and successfully advanced into a powerful Abyssal Demon.
Although he had reached the top of the devil's ruling class, Aston was not satisfied. His next goal was to become a Duke of Hell, a unique 'Singular Devil', which might take more than a thousand years, but Aston didn't care; he had time.
Beyond that, Aston yearned to become an Archduke of Devil, ruling any one of the eight planes of the Nine Hells and spreading his fame throughout the Multiverse, making all living creatures tremble before him.
And finally...
Each time he thought of such a possibility, Aston would shudder with excitement. The forbidden thought of absolute power lingered in his mind, unable to be banished.
