Kurayami No Nakade Hikari's
Prologues

Before the human race came two different races. The first race is the race of light in which justice and goodness are held in high esteem without knowing color, rank, or age. They keep the western part of the earth, while the race that keeps the eastern part of the earth is kept by a race of darkness which is filled with cruelty, and evil becomes a striking thing here. Thirsty cruelty is common for them. One day the light race made a barrier for both races because they were unhappy with their habits, because they were saddened by their habits. But the darkness race did not like the barrier made by the light race therefore they rebelled and wanted to attack, and destroy the barrier as well as the light race. The great war began after destroying the barrier created by the race of light, they were exhausted which made the creator angry. They were cast out of the earth, they were exiled in a different light race in heaven while the dark race was placed in hell. They are known as angels and demons. After the great war it damaged the earth heavily and had to recover and it took a long time the process was better known as the ice phase/ice age. After the ice age was finished created the first man on earth that caused more and more people on earth and humans were growing ever more stupid now start to show identity that knows that humans can be more come forward. The dark era began to disappear the destruction caused by the devil began to disappear human like animals who do not know what" who live in a destroyed world even though the human kingdom can stand. although demons and humans are far from one-dimensional but still the demons want to seize the earth where they say "humans are weak beings who are easily lied to and weak in all things especially with kindness". The demons began their action to conquer the earth, the first step is to make something impossible to do that is a link between the worlds yes it is a portal but they can not do it because it can only be done with material that is impossible to obtain that is golden water (heaven) that only exists in heaven as the name of the water itself. The demons had thought how to get it. They gave up, not long came two angels who approached them and instead they were enemies very far away. they thought the angel had come to attack them but instead made a pact to the demons "if you want to make that link then make me your king I bring something important to you" but because they hate the angels so much and they think what to do if they can kill the two angels, they immediately attacked the angel without thinking, but the results are not the same as they think an angel is very strong to make the 3 strongest demons died in his hand to see the power of the angel great they did not dare to fight him and make the angel their leader. One of the angels became the demon king/ruler of darkness, while the other became the accomplice of the king turned out they were a pair of sister. The demon lord also made a portal between earth and hell.

at that time the portal liaison was active and the demons were happy without a second thought they went straight into the portal when they came they saw a village and they carried out their destruction plan war was not spared.human war against the devil.where the war is not alone humans they are helped by the angels, the, that is by giving strength to a human who makes the war a big war draw occurs for 5 years known as the day of the heaven. in the end both sides agreed not to fight again because it took a lot of casualties, namely from humans and from the devil itself. the two sides sent in a portal guard force of five each, known as the Guardians. but still there are demons who disguise themselves as ordinary humans and live on earth they are not the messenger of the king but the brother of the king who wants to rule the earth alone without being with his brother. Who can change this fate the destiny of destruction.
