Recognized by My Ex After Being Reborn - Chapter 27 - : 027 Are they really not familiar?

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.

Crossing into a different world and impersonating the Lord of a city, a city encompassing five hundred miles, an elder sister having celestial beauty, and double digit number of lovers.

Tasked to revive a perilous family, Lanling, a third year university student, felt an overbearing pressure on his shoulders.

Hosting the Demon Star in his body, he can directly devour other people’s force and make it his own, he crossed through with a sole mission: To Utterly Destroy This World!

From being the Lord of Tianshui City, becoming the Queen’s husband, to being the World Destroying Demonic Emperor, he became the King of the entire world.
