9. Blue Exorcist
Humans & demons are 2 sides of the same coin, as are Assiah and Gehenna, their respective worlds. The only way to travel between kingdoms is through possession, as in ghost stories. However, Satan, the ruler of Gehenna, cannot find a suitable host to possess and therefore remains a prisoner in his world. In a desperate attempt to conquer Assiah, he sends his son in his place, intending for her to eventually become a vessel capable of being possessed by the demon king.
Ao no Exorcist follows Rin Okumura, who appears to be an ordinary and somewhat troublesome teenager, until one day he is ambushed by demons.

Not wanting to join the king of Gehenna, Rin decides to start training to become an exorcist so she can fight to defend Assiah alongside his brother Yukio.

Confused by this unexpected turn of events, the hero refuses to ally himself with his enemy, claiming that the war waged by demons is tearing apart the nations of the south.

Furthermore, she explains that if the war were to end, the supplies sent by the Central Nations to aid the Southern Nations would cease, leaving hundreds of thousands of people starving. She thankfully offers the Hero a way to end the war as he brings hope not only to the Southern Nations but to the rest of the world as well, though she will need his help to make this come true.

But just when he begins to feel an unusual attraction for her, her territory is attacked, resulting in Fuyumi’s untimely death.

1. Hataraku Maou-sama! (The Devil Is a Part-Timer!)
The show/manga of the Devil is part-timer is by far most similar to the great Jahy will not be defeated. Bith anime have the same setup and character structure. Both the anime takes place in modern-day Japan, essentially Demon lords trying to rebuild their armies by doing a part-time job.

After being confronted by the hero Emilia and her companions, having killed Malacoda & Adramelech, Satan and Alciel escape the world of Ente Isla through a door to modern-day Tokyo, Japan.

One day, Satan, who now calls himself Sadao Maō, meets a girl who is actually Emilia in the form of Emi Yusa.
