After being transported to another world, Naoki finds himself in the midst of a deadly conflict between humans and elves; with humans enslaving elves for money, and elves killing humans in retaliation.

A mysterious deity commands him to join the Knights of the Sacred Flame--a human extremist group waging war against the elves. A fated encounter with the Elf Princess leaves him traumatized, yet compels him to lend her his aid.

Will Naoki join the humans or will he go against the grain and fight for what's right.
