Karvia Kurlsevni

The Empress of the Demon Empire, which boasts the largest military power of the four nations on Helvetia. With vast magical energy, she is considered to be the strongest Demon in recent history, having been the one that defeated the goddess in the war.

Cold and ruthless, she rules as a tyrant with overwhelming power, executing anyone she doesn't like or agree with. Due to this, she has become known as the Dark "Empress."

Having waited for the chaos following the battle against the goddess to settle down, she took advantage of the momentary peace to advance her plans to take over all of Helvetia, starting an all-out war among demonkind.
