Chillin' in My 30s After Getting Fired From the Demon King's Army

Dariel, a grim warrior in the demon king's army who cannot wield magic, rises to the role of assistant to the Four Generals through sheer talent and energy. However, when the Four Generals are replaced, Dariel is dismissed from the army. Devastated, he arrives in a human village and discovers that his adventuring skills, once deemed useless to demons, have blossomed. "I was... human?" he wonders, deciding to spend his second life in this village, and requests begin pouring in. Trouble! False charge! Duel! With his natural skills and the adjusting power he honed in his former post, the former dark soldier solves them all!
