Synopsis
The kingdom of Sforzando is under threat as demons begin to emerge, wreaking havoc and endangering the lives of the people.
This demonic invasion is linked to a weakening barrier that has long protected the human world from these creatures.
Queen Horn of Sforzando is the one maintaining this barrier, but her power is fading, making it vulnerable to the forces of Hell King Bass.
Bass seeks to break the barrier entirely, releasing Kestra (Orchestra), a powerful being currently trapped in the human world.
The anime seems to follow the struggle to protect the human world from the escalating demonic threat and the potential release of Kestra.
