Kaiko sareta Ankoku Heishi (30-dai) no Slow na Second Life

Dariel spends more than 30 years as a loyal soldier in the Demon King’s army despite being unable to use magic. The moment Bashbarza inherits one of the Four Heavenly Generals’ positions, he fires Dariel as useless, leaving him without the only home or purpose he has ever known.

After rescuing a human woman named Marika from a monster, Dariel is welcomed into her village and discovers a truth that overturns his life: he lacks demon magic because he is actually human. More than that, his human abilities are extraordinarily powerful. Dariel finally finds a quiet life and people who value him, but he cannot stay outside the human-demon conflict forever, especially when his knowledge of both sides and his newfound strength begin drawing the past directly toward his new home.
