The Vertexes (バーテックス; Bātekkusu) are a malevolent lifeform, created by the gods of heaven during the Anno Domini era for the purpose of exterminating mortal life. They've succeeded in destroying much of the world, apart from the Shikoku island of Japan which was protected from certain destruction by the Shinju-sama, a coglomeration of gods that sided with humanity during the humanity-Vertex war. In order to further continue protecting the remnants of humanity from certain extinction, Shinju-sama borrowed chunks of their divine powers to young girls, which will eventually become known as Heroes.

Additionally, Vertex can form Starclusters, such as the Leo Starcluster (レオ・スタークラスター; Reo Sutākurasutā). These Starclusters gain the abilities and apperance of the Vertex they're made out of.
Vertexes were created as cleansers with the purpose of passing down divine judgement upon humanity. They first appeared on Earth during 2015 AD, and have continued to attack it even 300+ years after.
