My Life in Another World Is Dreadful

Having lost everything, having been saved by a friend thought lost to the memories of his past, having no choice but to embark into a foreign land to fight into a crusade that yet is not as it seems, the one known as Hum has but one purpose in this strange new world. To survive, and find peace with his ghosts, with the reality he is surrounded by, and perhaps who knows, even get his revenge while on the way through the Republic of Valvia, who is not a Republic, and whose crusade against heretics might in truth hide a darker secret.
What is honor? What is right, or wrong? Does it even matter when you're but a simple man holding a sword and a shield amidst many others? With powerful Xiuzhe achieving abilities beyond the ken of humans, and Gods snuffing those powers out within sight of their priests, everything is interwoven into yet another series of clashes.
Not just for supremacy or conquest, but for the very right to exist.
