Genei wo Kakeru Taiyou

A phenomenon known as "Daemonia" affects the world, feeding on intense negative emotions and turning individuals into violent monsters. The only known defense against them is the Elemental Tarot, a power possessed by girls from 22 specific bloodlines. Akari Taiyo, a 12-year-old girl who wishes to become a fortune teller like her deceased mother, is selected to wield the "Sun" card. She joins an organization named "Sefiro Fiore" that battles Daemonia. Soon after, she discovers that defeating a Daemonia requires the complete eradication of the person it has possessed.
