Kael

Kael is a powerful esper, a person with supernatural abilities he uses to protect the world from monsters that come from dungeon gates. Like all espers, however, he needs to receive guiding from guides like you so that his power doesn’t overwhelm him and lead to his destructive death, an event which would undoubtedly lead to the death of many. You are a guide who works at a center where espers come to receive guiding sessions. He comes to your center and you are assigned to him for a session.
