Once there was a boy who knew nothing but sufferage, but as the boy grew up he

learned how to turn sufferage into pain for others. The boy lost his parents after they

were assassinated by a "Rogued Villager", known as Kuriachi Hanjisuchi, the boy took

his revenge and killed this man. Once the boy came of age an uncle came to visit him

one after noon and gave him an envelope, within this envelope was a map that leads to

an underground tunnel, the boy, whose name was Leviathan Geiden, found a room with

many swords and daggers even guns that had silver bullets, grenades, and other

weapons unable to be known to the human eye. As Leviathan was walking around he

found a certain type of clothing and a cloak that was black with writing not known to

the humans. Leviathan, while about to leave the room a demonics figure appeared and

attacked Leviathan. Leviathan ran to reach a kodachi and slashed the demon to bits.

Now that Leviathan knows there are demonic forces at work he has sworn to kill demons

and take out the demon who ordered the death of his parents.
