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.

The cousin that Jing Huan has been closest to since he was a child was labelled as “the other woman” in a certain popular online game: only after devoting herself did she know that the other party was a jerk with a girlfriend.

After several days of being bullied online by people in the game, his cousin went abroad in a fit of anger and sorrow.

Jing Huan couldn’t take this lying down; he decided to take revenge for his cousin using the same method as that guy – buy a character in game and kill that slag guy thousands of times online.

With his strength and skill as the Great God when the game was first launched, wouldn’t he be able to kill that guy and force him to quit the server in minutes?!

He went online, eager to fight, but made a discovery after conducting a round of investigations — this slag guy was the number one DPS server-wide, number one on the expert ranking list, number one on the wealth ranking list, number one on the popularity ranking list, and number one on the fame ranking list.

Conclusion: Can’t screw him over.

Jing Huan felt despondent. He was just about to give up when he personally witnessed his dormmate’s online relationship end right after meeting each other in real life. The other party had sent fake photos and changed their voice, and had even cheated him of his money, triggering his dormmate so much that he was almost admitted to a hospital.

Jing Huan felt enlightened as a sudden realisation dawned on him. After comforting his roommate, he moved the high-priced voice changer back to his rented house overnight.
