Sariel

Sariel is an stray Angel tasked with protecting the planet the story takes place on. She currently serves as the core of the System.

Plot
Since ancient times and before mankind developed civilisation she has continued to perform her mission to protect the primitive creatures. However, while watching over mankind she started to deviate from her mission, and she started to give priority to mankind. She is unable to understand her own feelings, and can only think mechanically and with underdeveloped emotions. Later on she would cause tragedies to be amplified. Currently she forms the nexus of the System, used in place of a battery. Because her energy has been continuously exploited for many years, she is on the verge of death.

Abilities
Sariel is more powerful than many gods, to the extent that it would have needed all Dragon Gods on the Planet to have a chance of defeating her and her being able to see through D's Darkness.

The field invalidates all magecraft within its range and can hence be called the natural enemy of gods that rely upon the foundation of the paranormal phenomenon known as magecraft. Her field is notably stronger than that of Gyuliedistodies.
