The Hidden Lord Next Door

Gustavo Sanz is the heir of the god of war. He gives up that identity, comes down from the mountain disguised as a food delivery man to see ordinary life for himself, and marries into the Castillo family as a live-in son-in-law, where he is treated with contempt. When his martial art is finally complete he fights the demon lords of the four marches, holds the border of the country, and builds a record of his own. The Castillos, who worship money and despise the poor, cut him off entirely. The Gil family, who have influence and use it, push people around. Gustavo answers them with an iron hand, punishing the ones who deserve it and standing in front of the ones who cannot defend themselves.
