Introduction

In world of devils, fallen angels and angels' existence as majority of humans did not know the supernatural were keep secret besides the church knew their existences. These supernatural beings almost forgotten three certain creatures created by God and each of three creatures rule their own domain of Earth itself.  Ruling over oceans, the lands and the skies of planet earth then first one know as Leviathan being a large sea serpent in most describes of it. God saw Leviathan's nature grew into clever, poisonous and a possible threat against the human species or all life of earth in the future. Response to the problem at hand God imprisonment Leviathan but, it seems like the creature gave birth to offspring before being capture and putting it into a prison held in. Leviathan's originally prison was not known among the first angels and was not mean to hold one individual beast, since God changed his mind after seeing Behemoth the second out of the three was eating everything its path on ground and nothing can satisfy its hunger. Know to being a gigantic beast of the land and mixture of both reptile/mammal for appearance wise to the poor sap that survive the tale of being chase by the massive land being. God soon put the gluttonous creature into temporarily prison before making a decision soon solve a future problem both Behemoth and Leviathan is putting Ziz the final one of three primordial supernatural creatures with them in a single prison.

 Ziz the featherily beast where people hard know about it due rare occur of seeing it flying among the skies. Scrips of a certain book says it protect against the storms of south, but roughly the same monstrous size of the Leviathan while the book says it head reach the very sky and ankles on the earth. God plan was simply to have Ziz to act as somewhat warden on the two and final prison house of the Behemoth and Leviathan was ironically a sacred gear due the concept of building it. Being guarded by high-ranking arch angels of heaven and chains around the sacred gear with multiple locks on it. Magic Seals were place around the sacred gear to prevent anybody entering area of it upon the person have the skill and power to defeat the arch angels.

The years to come and somewhere in the scared gear it seems were talking to each other as over the years in this imprisonment all three creatures were just getting tired of being held in place and want to get out of it while they made an alliance each other. "How many years has this imprisonment been? "A voice grunted sounded rough belonging to creature with horns appearance could say maybe hybrid of mammal and reptile creature as this was Behemoth then a voice answered, " It been over two centuries for you, and do not you remembered we are stuck here for internally". "Yes, but I am getting tired of being here! "Behemoth growled at the voice belonging to a griffin like bird and voice of the creature was muscular it was Ziz as he replied, "Yeah I am but not only getting tired of this too?". There was large barrier separating of two as but they can see each other through it and both they were getting close to barrier but for Ziz he have fly down little bit meet Behemoth because he was ironically place on top to watch Behemoth and Leviathan then there was an giggle and two of them look at creature is an gigantic size of Ziz also with some wings on it and slightly also voice of the creature was genuine and look serpent as it said "calm calm down boys you getting angry of over just topic we stuck on and I may have solution our problem "."Which that is ?"Behemoth and Ziz asked same time to the creature was the Leviathan and she has clever smile on her face then she answered "that is escaping from this imprisonment maybe with an plan I made ". "Tell me this plan than the others will work our escape?" Behemoth says over the years he and her was try escape this imprisonment before they made alliance with Ziz then Ziz added "and how the plan will be different the others "."Well I figure it out that one of these seals holding us and one of them can move our imprisonment that maybe help us escape "Leviathan answered as she looked at them and she was place next to Behemoth as she has small body of water she is in which is lake that to give her little room then Behemoth replied "Good and which seal is holding ".And which seal is can move our imprisonment "Ziz asked as Leviathan pointed at seal was on barrier and she answered "well figure out that seal is either one can help us escape or holding us but we need use our strength against "."So you don't know it could be the one holding us or help us escape "Behemoth says and Ziz replied "you know our strength is limited by this imprisonment "."I know but we could combine our strength to break it just me " Leviathan answered as she looked at them and both of them look each other then Ziz said "let's do "."Yeah and hope this plan works "Behemoth reply as all three then gets ready to attack the steal on the barrier then Behemoth goes leap at it as Leviathan goes lunged at it and Ziz dive bomb at the seal once they made contact at the seal there was brightly cover whole area meanwhile outside of the sacred gear which is was in glass box with some seals on it as an angel in armor was going check on the condition of the sacred gear is and four angels were guarding around the glass box on an stand .The angel stop walking to it as noticed slowly blinding light was growing inside of glass box and four angels was guarding the sacred gear when the light start to hit seals and seals were start to breaking as glass box was also breaking too then four angels was guarding the scared gear quickly back away from it and angel in armor says "quickly seal it off before they escape ".As five angels use their magic to make holy light barriers around it and soon three angels come in to help as the light was keep growing inside of scared gear as all three primordial was still on the seal and keeping use their combine strength on seal then they noticed it was breaking behind the brightly light and Leviathan said "keep on using our strength!!!"."I am escaping from this place and I am not losing here !"Behemoth yelled at him, Ziz and Leviathan keep on using their strength on seal as the seal was getting close breaking it when it finally breaks there was huge explosion as throws them backwards and outside the light cover the room then all holy light barriers around the scared gear begin explode as angel in armor have to cover his eyes while the holy light barriers exploded which cause chain reaction to others around close to one's was around the scared gear and blast everyone back.

Smoke comes from explosions the sacred gear was large heavy armored gauntlet with different symbols on it and begins to launch off like an rocket as angel in armor open his eyes was on ground from the blast to see sacred armor was going up to ceil quickly the breaking through it with two items follow close behind it then angel armor in armor was slowly getting up as watching the sacred armor fly off somewhere and he said "we need tell Michael about this ".Once the sacred gear was up in the sky the two items was closely behind it combine with it and those two items were an double bladed spear and metal bow now also back inside of scared gear Leviathan and Behemoth were on ground as Ziz was at the ceiling it's seem the light blast them backwards while they open their eyes slowly to see the barrier has been gone and voice said "pick an person ".As giant screen appeared filled with names and has different color dots on it then Leviathan slowly gets up to see names as Behemoth follow behind her but getting up taken him little bit more and Ziz was slowly recovering from the blast as Leviathan look at names on screen and she stopped looking at screen. "Mm pick a person heh? Well this will be hard "Leviathan said as she looked at the last name on the screen as Y/N L/N and she tried to figure out what this then she got a feeling and Behemoth asked "why do we need to pick a person ?"."I don't know but I got a feeling to choose this person and maybe will help us "Leviathan answered as she goes tap on the name is Y/N L/N and as Ziz dive downs because he remember the talk he have in past to someone then he shouted "wait!!!".As the screen disappeared and Leviathan also Behemoth back move away little as Ziz goes land on ground then Behemoth and Leviathan look at him as Behemoth says "too late she already choose an name from this "."Why you choose name before I fully recover !"Ziz replied as he look at the Leviathan as she her clever smile slowly emerges and she respond "Why ?because I feel this person I choose will help us and relax. We need to fully recover from the blast of the seal we broke "."I agree "Behemoth says as he goes lay down and Ziz just sighs back outside of the sacred gear begins turn an specific direction and it goes to that direction from the light on back of the sacred gear as it was shooting the light backwards like an missile heading towards it target then and two angels was guarding the an shelter which once hold the sacred gear saw the light from the skies and the angel in armor was coming out of the shelter saw the light as thinking it was scared gear ."Go after that light because they are escaping from here !"Angel in armor says as the two angels nodded and go after light but soon lost in clouds because scared was becoming smaller for an reason and the two angels come back to tell the angel armor also other angels they lost them then back to the sacred gear was going certain hospital before specific mother was about give birth to an baby and the sacred gear size now to where hardly no one can see it once the scared gear goes into the mother. As it quickly goes into the baby and after few minutes of the pain giving birth to an child was over while how the scared gear get inside of baby by the magic around that is harmless and leave no wounds it just phase through then inside of scared gear notice that start to change and Leviathan's lake becomes alone while the land of Behemoth was becoming an large island and there was some clouds up top where Ziz is ,as outside of the scared the nurse wrapped the baby in clothing. "Here he is "Nurse said as she hands her the baby and she saw baby while guy comes inside of the held his wife saw the woman on the bed then he walks towards her, and he said, "he got your eyes and what you going to name him?".
