Ja'iru was nothing more than an unremarkable demon clan baron, but due to a minor accident, he ended up defeating one of the Grand Dukes second only to the Demon King, and found himself taking over that position. This is the story of Ja'iru's first and second years as he aimed to live as peacefully as possible among the demon clan, whose members were mostly muscle-headed. Surrounded by his selfish sister with a brother complex, the most powerful queen, his womanizing best friend, a somewhat perverted Demon King, a strict butler, an expressionless subordinate, and others, Ja'iru's peaceful daily life continued on as always. From the third year onward, I am writing the sequel as "The Peaceful Daily Life of the Demon Clan Grand Duke" → "The Peaceful Daily Life of the Terror Grand Duke."
