Grimoire

Grimoire is an Etherious, a demon created from the Books of Zeref over 400 years ago. He is among the most dangerous demons within the Eleven Demon Lords.His strength has made starved for a true battle capable of stretching him to his limits.He was among the demons who would frequently go out "Human Hunting" and performed some of the most atrocious human massacares in magical history.However he was among those who supported the leaving of the Tarturus Guild and is now part of the Thirteen Demon Lords who are charged with the protection of Demons from humans and to ensure Demon do not interfere with Human affairs.

Personality
Grimoire's personality can be said to be the polar opposite of Absalom's.Where Abasalom does not enjoy needless fighting Grimoire enjoys it more than anything,he enjoys fighting oppenent a ripping their body to shreds.This blood lust led to him being given the title Sanguine's Blade.He constantly looks for ways to surpass Absalom in power,in should not be mistaken Grimoire has nothing but respect and loyalty for Absalom but wishes only to surpass Grimoire physically and magically.

Grimoire is the most active of the Eleven Lords always taking it upon himself to find demons and discipline them such that they refrain from disrupting human life.How unbeknowest to the other Lords Grimoire has at times mercilessly killed several demons he has deemed "unsuitable" to continue life.Whilst most of these demons were among those who wanted to bring about the end of the human race a good number of these demons were innocent and simply were unfortunate enough to come across a fight hungry Grimoire who even as he beats the life out you will continue to complain about your lack of power.
