Plot
Dariel is a non-magical soldier serving the demon army as an aide to the demon lord Bashvaza until he is fired by him. Having nowhere to go, Dariel sets out into the world when he saves a human girl Marika, and is invited to her village. When Marika got him registered into the Adventurer Guild, Dariel discovered that he is actually human with an extraordinary talent in swordsmanship compared to the Hero. While things become worse in the demon army due to Dariel's absence, Dariel gets used to life among humans but is conflicted with his demon upbringing, as humans and demon society have been at war for centuries.
