Sun and Moon’s Will

"… Heaven's Stealer!"

Those two mildly spoken words resounded like thunder in Ace's mind as he had never expected to hear them from anyone other than the system. Maybe that's why he was so shocked, or it was just that his biggest secret had been seen through by this mysterious voice like it was nothing. 

Ace always thought that no one would be able to tell his true origin and what kind of status he represents. But now, the realization stuck with him hard. He always had this strange thought deep in his heart, which he never paid attention to, but it was always there. 

It was now become quite clear that he wasn't the first Heaven's Stealer. There were others like him who had walked on the same path that he was walking. But just how many were before him, what were their endings, and how they met their ends? 

But one thing was abundantly clear; since he was the current Heaven's Stealer, the one before him was no longer in this world.
