Thanks for the invitation! I am in hell and have just become a demon king

After traveling through the world of Demon High School and wandering around in it for a thousand years, when Chen Eliog became the fifth demon king of the underworld, he received an invitation from a dimensional chat girl.

Out of boredom, Chen Eliog chose [Accept].

Cang Yue: Welcome newcomer! I am the strongest fighter among all the girls, let me know!

Esdeath: The person above is talking nonsense! I am the strongest fighter among all the girls, let me know!

Yukinoshita Yukino: Hello newcomer! As an ordinary person, I am trembling between two big guys!

Shinomiya Kaguya: +1!

Chen Eliog: "Thank you for the invitation! I am in hell and have just become a demon king: I have official business to attend to, so I will hide for the time being."
