Alciel

Once known as Alciel, the most brilliant tactician in all of Maou's demon forces, he served as the Dark Lord Satan's most trusted confidant. After retreating to modern-day Japan, he assumed the human identity of Shirō Ashiya and voluntarily took on the role of full-time housekeeper. While the Demon King works part-time shifts, Alciel manages every household chore with iron-fisted financial discipline, stretching every yen to its absolute limit within their cramped six-tatami apartment. A former warlord of the underworld, now a surprisingly formidable domestic manager.
