Karen

Karen is a Valkyrie and the former leader of the Bright Cross Disaster Prevention Foundation.

Appearance
Karen has straight, waist-length blue hair, skin that is almost transparently white, and curves that give her the perfectly-proportioned feminine beauty of a Greek sculpture. When acting as the announcer for the Bright Cross, she wears a bunny costume that is sparkling blue like a rainforest butterfly. When she reveals her true nature as a Valkyrie, she adds bird wing decorations behind her ears and a cloth around her hips. She also carries a gold cross-spear and a round one-handed shield.

When Karen returns after being killed, she instead wears a suit of blue divine armour that includes a miniskirt.

Background
As a Valkyrie, Karen had the duty of both fighting as a warrior for the goods and to descend to the lower world to marry human men. She would smile with her neighbours, seal away her power as an immortal, complete her housework with her own power and even pay taxes, all to remain with those she loved. However, she faced persecution from humans who considered her no different from other Archenemies. Armies were sent against the Valkyries, burning down their houses and killing their loved ones. Karen decided to become the Archenemy they saw her as and took revenge on the armies.

Karen tried to fill the hole opened in her heart. She tried again and again, finding a new man and trying to redo things, only for someone to cruelly intervene each time and cause her to take revenge again. Eventually someone else realised that humans would always be a problem, but if they could gather together and redirect those problematic aspects, they could prevent them from doing harm. Karen and others who thought this way thus created the Bright Cross.
