Drifting towards Rebellion

When Shimazu Toyohisa awoke it was not a world of fantasy he was in. It was Japan...over 400 years after the Battle of Sekigahara. His homeland has been enslaved, and now he finds himself working with the thought-dead Demon King of the Sixth Heaven and a hero from the Genpei War. Then a certain Britannian prince joins the fray. This world was destined for more than chaos.
