Biography:
Back in the ancient ages before existence, there lived a lonely god. He was jealous of how everyone else around him has a significant other. Out of spite, he created a world and put a lonely man there to make him feel what it's like to be alone. However, the yin-yang man was happy being single. Out of spite, the lonely god separated him into two, a white male yang half and a black female yin half, both only having one eye. Through trials and tribulations, the yin and yang halves work together until they reunite into one again. The lonely god was angry and for a while, became the sun to his world before abandoning it. However, the world he made then reached to an equally bitter lonely goddess. The lonely goddess went to the lonely god and became significant others to each other, removing the bitterness in them. The moment they became the sun for their world, the world containing the yin-yang man went haywire and got sent to another universe.
The yin-yang man's world soon merged spiritually with the world it got sent to. As for the yin-yang man, he lay collapsed until a group of kids found him. With the help of many parents, the yin-yang man got help and soon, established his own identity as a man named Opus Seth. Afterwards, he decided to travel around the world, looking for answers for any questions he fascinates himself in. With the ability to separate and unite himself at will, he will live an answering life.
