Strange beasts known as Demons who fell from hell that are hiding from the shadows are slowly causing people to kill themselves and commit crimes. One day, these beasts came out of the shadows and attacked humans. Ever since that day, the government is warned citizens to stay inside. However, one day, a girl was injected with “Shiu”, a magical ability that’s made to fight these beasts. Then, the same girl transformed into a Magical Girl and slayed the beast. Now, Magical Girls have been revealed to the public eye and they are now ordered to not only help people by day, but kill Demons at night.
