Disclaimer I don't own Familiar of zero or soul nomad would be kinda cool if I did though

She had done it she had showed all would think to use her as their weapon in their petty little wars. Dead, every single person dead oh they put up such a pathetic final offense on her but they were nothing compared to her power after all she had the master of death on her side even with World Eaters with them they paled in comparison to her. The look in their eyes as they slowly realized how hopeless their struggle was, she had shown them why she was called the Devour Lord as she consumed the souls of the fallen. In the end only her and Gig remained, Gig her companion through her rampage across the land, it was he who showed her that her family simply wished to use her to fight the World Eaters, it was he who gave her the power to fight against all who opposed her, but in the end she was so hungry, so very hungry and there were no more souls to consume but his the hunger was madding and despite his pleas she devoured him. The power she had gained was unimaginable but she was alone now there was no one for her to eat she had gained so much power but there was nothing to kill nothing to destroy. Then they arrived the gods of the world Haephnes and Drazil they had spouted nonsense how she was reasonability now that she had gained powers that rivaled a god but she didn't care all that mattered was that there were people that she could kill people to consume. They had merged their power to try to defeat her but it was useless they still fell to her blade the world began to decay and die without the gods to maintain them.

She sat in the ruins of her castle as she watches everything slowly die around her the trees look sickly nothing grows animals perish she didn't care. Nothing there was nothing for her in this land she was alone.

"My servant that exist somewhere in this vast universe"

She looked up that was a human voice she heard she stood her onyx blade in hand as her empty eyes scanned the area around her could some pathetic human have survived her genocide?

"My divine, beautiful, wise, powerful servant"

Divine? Heh she was as far from divine as you could get, beautiful? She was called such by many in her army and occasionally Gig even if he wouldn't admit it, wise? Maybe but powerful she was certainly powerful however she was no one's servant no one's tool and she would kill any who dared to use her in such a manner.

"I wish from the bottom of my heart and add to my guidance and appear"

A green like portal appeared in front of her and she thought about whether or not to enter it but there was nothing for her here nothing to eat nothing to kill so she stepped into the portal.

Louise coughed as she waited for the smoke to clear from her summon attempt the familiars around her began to shake in fear Tabithas dragon attempting to drag her away in fact many of the familiars her trying to drag their masters away.

"What could possibly be scaring them so baldly is it the familiar I summoned?" Once the smoke cleared she could she what exactly has been scaring everything.

It was a young girl maybe 14 or 15 years old she wore sandals and white pants that reached a little bit past her knees she didn't wear a shirt only armor like bra of sorts. She had red gauntlets on her hand s with a green sleeve reaching to her shoulders she had a green shoulder pad s an onyx blade in her right hand. Her face could be considered quite beautiful by many, blood red hair streaked with silver reached to her shoulder and covered her left eye from view her right eye was a freshly spilled blood red and looked empty and devoid of much emotion she had a light tan from that you would expect from someone who spent much time outdoors. However it was her presence that terrified Louise it screamed death and despair and many people had collapsed around her already it was like standing in the presence of death itself.

Professor Colbert was a soldier he was used to death and having worked under Karin the heavy wind was not easily intimated but this girl was terrifying him she looked fragile like she could barely swing the blade she carried but something told him that Louise should bind her as a familiar imminently or else the girl would kill them all.

The girl raised her blade and pointed at Colbert before saying something in a strange language he quickly cast a spell that would let them understand her. "Where am I?" her tone was empty and lacked the usual emotion that a voice usually carried "you are at the Tristanian Academy of Magic miss …?"

"…..Revya" was the girl now known as Revyas response

"Ah well then Miss Revya you have been summoned as a familiar by the young Miss Valliere" Colbert explained in a calm manner but was still prepared to cast his spells in case the girl attacks

"Familiar?" Revya tilted her slightly while she waited for Colbert to explain.

"A familiar is a creature that is summoned and bound to mage in order to assist them in any way possible" Revya grip on her blade tighten and the explanation.

"Bound? As in enslaved I have been called forth to be a slave to the girl here" Revya's onyx blade began to be enveloped in her dark energy she will not be enslaved she refuses to be used by someone. Kill…yes that's what she will do she will kill them all there no match for her she's killed gods after all what's a few little mages to her.

"heh very well little mage try, try and bind me to you " Revya charged at Louise with every intent to kill her until a fireball crashed into her knocking her to the side . She glanced to the left and noticed Colbert had his staff pointed at her .

"You shall not harm my students" The man was serious he really thought he could stop her, The Devourlord from killing anyone who annoyed her.

"hahahaHAHAHA you think you can stop me little mage your nothing but maggots to be crushed under me I will enjoy watching the hope in your eyes fade as I kill you students in front of you" Revyas voice which usually lacked emotion was now filled with a sort of madness and joy that she feels when in battle. As she raised her blade now completely coated in her dark energy as a sadistic smile slowly formed she was going to enjoy killing every single thing on this world starting with the girl who thinks she can enslave her.

So yeah had Louise summon Devourlord Revya just for the lolz don't know how exactly Louise will get close enough to bind her as a familiar but I do have an idea for how to curb her genocide instincts . Her appearance is a slight mix of her with Gigs hair color mixed in as well as Gigs personality slightly merging with hers due to the whole consuming him thing she did. I have a feeling she might be too powerful to be used in this series when you considered that she did kill 2 FREAKING GODS but I suppose I could come up with something if I continued this.
