A Peaceful dungeon
Amidst stories of breathless survival and bloodshed, this work carves out a sanctuary of quiet respite.
The protagonist, Yuki, was once a human from Earth before unexpectedly reincarnating as a black-haired, demon-winged Demon Lord.
With the Demon Eye in his right eye and a deep connection to the dungeon core, he takes up the mantle of protecting his domain.
Initially, Yuki pours all his energy into bolstering defenses against a violent world teeming with colossal monsters.
Yet, he gradually discovers an unexpectedly tranquil life alongside non-human companions.
Management and Family
The author weaves a domain-building system around the convenient resource of Dungeon Points.
Utilizing his Demon Lord of Creativity skill, Yuki infuses materials with mana to craft weapons and items.
Even as he reinforces his stronghold, he transforms it into a haven of peace for his eclectic family.
The presence of Lefisios—a sweet-toothed supreme dragon in the guise of a young girl—infuses their daily routine with vibrant life.
She is joined by the young vampire Iluna, the Hero Nell of the human kingdom, and their maid Leila.
This home is rounded out by the slime Shii, the Fenrir Fluffrir, and the beastgirl Lew, all sharing a sincere bond.
