Vermilio

ヴァミリオ

She is one of the Four Heavenly Kings of the Empire. She was ordered to manage the tournament held to inaugurate the next Demon Lord. She is very wary of Helck since he is a human and hates being referred to as Vamirio-chan.
She looks grumpy but is actually a good girl; while being hotheaded, she is also cautious and has very expressive reactions. She calls others and herself stupid and has a hard time trusting newcomers because she cares about the well-being of the Demon Kingdom and its civilians.
She can use fire and summoning magic and excels at fighting several enemies simultaneously.
