He was on his way to buy some beer to celebrate his acceptance as a civil servant when he was suddenly isekai’d by truck-kun.

After being adopted by the Su family for so many years, Su Yan had always been grateful to them for raising her.

Within the walls of her family, she was filial, kind, and did everything she could to please her family. Outside those walls, she and her fiancé, Huo Nan, were on par with each other. They were an immortal couple that was respected by all. She loved Huo Nan to the core and even gave up her kidney for him.

This continued until the real daughter of the Su family, Su Qian, returned. Huo Nan betrayed Su Yan and climbed into Su Qian’s bed. He even allowed Su Qian to wantonly frame her and disfigure her!.

Su Qian even slandered Su Yan for seducing her fiancé. The Su family believed her and insulted Su Yan with the most unpleasant words in the world. However, they forgot that before Su Qian returned, Huo Nan was Su Yan’s rightful fiancé!

After she was killed, Su Yan was reborn to her 18th birthday and started her crazy path of revenge. Step one, inherit assets worth billions; step two, kick the scumbag to his death; step three, personally slice her white lotus of a younger sister.

In this life, all she wanted was to live an ordinary life with her blind and lame husband. After all, this man continued to help her willingly in her past life even though she rejected him countless times while her dearest husband betrayed her so ruthlessly!

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.
