[About this world: In this world there are evil Demi-Humans and they are used as weapons, companions, slaves; But because of their evil genetics, they wear a special necklace called the wisteria flower necklace; Wisteria flower contains a strong smell and poison to control the great strength and large body of Demi-Human demons. All Demi-Human demons must use the wisteria flower necklace, and some demons that are more wild must even consume the wisteria flower in pill form; Some humans are against this process of enslaving demi-human demons and even against using wisteria flower for demi-human demons. The original origin of Demi-Human demons goes back to Japan. Until now, it has been exactly 56 years that Demi-Human demons have been used as slaves, tools, and weapons. 】
