Teogonia Episode 6

Humans are forced into an endless war in hostile borderlands against demi-humans bent on stealing their lands and their gods. While defending his tribe, a young man named Kai suffers a life-threatening injury that gives him memories of a previous life. Unless you're a protector, it's like playing life at full speed. After learning more, Kai gains a new perspective on the unfair "set of rules" that controls his environment. One thing is certain: life is a constant struggle for survival for humans who have no god to act as their protector. Thus begins the epic tale of a young man ascending into a vast world of magic, blood, and mystery. (Source: J-Novel Club)
