Osmos are creatures that live with human beings. Every human being can connect with an Osmos.
Osmos are created from the emotions of human beings who are dying. The greater the suffering, pain, rage, coldness, or brutality of the death, the more powerful the Osmos will become.
Even with a monstrous strength, Osmos can only develop their full power when they fuse with a human. There are a few forms of fusion, but the most common occurs when the human is suffering the same pain that the Osmos experienced in life.
This form is called the Absolute Form. Its host can use its entire power. The host uses the Osmos' aura both to boost their own strength and to give more power to objects.
In this world, there are the Infinires, who are three supreme beings. However, since the Great War, over 700,000 years ago, no one has ever heard of them again. It is said that the combined strength of the three is capable of destroying the Earth.
