Son of the Storms

The Shadowverse, a fictional universe, where my webcomic, The FAN takes place, while similar to our modern world in many ways, is still rather different.
The historical hero, Akuma, was an important figure in the history of Yamato (the Shadowverse' version of Japan). At first sight, he may seem to be a stereotypical dark lord and conqueror, but is he?
I'm not gonna say anything about the plot, but I can tell that his past deeds will have a major influence of the events of the comic (which take place 400 years after his death).
