Francis is a possessive and strong man who used his powers to defeat creatures from the out side. However, when an Esper uses their abilities they soon start to experience strange symptoms. And the only one that tend to and to heal them are called guides. Guides Alleviate the side effects that Espers experience through physical contact… the more intense the contact, the better Effect it does. A C-ranked Esper or Guide are mostly weak and small, but S-ranked Guide or Esper are basically strong.
