Itogami, Meiga

絃神冥駕

He is a prisoner who managed to escape alongside six others, including Aya Tokoyogi, when the seal on the Prison barrier was broken. All the prisoners then agreed to help Aya find Natsuki Minamiya and kill her so that they would be completely free. However, he was the only other criminal smart enough to avoid searching for her, having deduced that since Aya Tokoyogi had acquired all of Natsuki Minamiya's memories and time, she had become the key to the prison barrier. He claimed that all the other prisoners were now searching for no reason. Furthermore, he stated that he would not spoil her plan because it would also benefit him. He also noticed that Asagi could be the priestess of Cain.
