Astral Pet Store (WN) - Chapter 1517 - Suppressing Ancestral Gods

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future.

However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.

Arnos enrolled in the Maou Academy established to find any students that might be the demon lord’s reincarnation, but his powers are too extraordinary that those in the academy couldn’t properly judge his powers, so he’s regarded as an “Inept student”. Being underestimated and avoided by most people there, he recruited a girl friendly to him, Misha, as his subordinate and comrade, and strives to climb to the top of the demon race hierarchy to one day reclaim his former title and status.

At the end of the dark 40,000 years, the enemies in the Milky Way launched their final offensive. When the end of the Era comes, the eternal war will come to an end. The human empire has now reached its destined final moment.

But the gear of fate does not end. The fate of the Milky Way will be determined by him and them as it was ten thousand years ago. What will happen at the end of this dark 40,000 years?

- Description from novelbuddy

For others it takes dying and reincarnating for them to get a system but what happens when you get one without dying?

Aron Michael is an average student set to graduate within a week, but he was expelled for a random reason. Due to that, he had heavy student debt and no diploma to help him earn the money to pay it back. But one day he got a system that called itself the [Advanced Tech System].

Follow the story to watch him develop from your average Joe to him being the owner of the largest company in the world.

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.
