Welcome to Demon School! Iruma-kun!

Cordelia Seaborne is a demon siren from the Netherworld. Cordelia has a beautiful singing voice, but there's one thing about her that some may might know, she has stage fright. Cordelia freezes stiff whenever she goes on stage, so her family helps her step by step to conquer her fear, and so far, she can handle a small crowd. When the school year has started, she meets her childhood friend, Asmodeus Alice. He was excited to give an opening speech at orientation, but he wasn't able to due to the sudden appearance of a new student, and his name is Iruma Suzuki. And he's the grandson of the principal, Sullivan. Cordelia has grown curious about Iruma, especially since he's the principal's grandson, but he never had any children of his own

Cordelia will experience a lot of crazy and fun adventures, some will be dangerous or random. All that Cordelia knows is that, her life is gonna a fun one to remember
