The Adventure of Sin Cos Tan

What would happen if a God, a demon, and a human made love to each other?

This story tells of 3 twins named Sintri, Gonocos, and Tan Metri who go on an adventure together to find their biological parents after what happened to their orphanage. Because all this time, the three of them just lived comfortably in an orphanage with other children.

There is only one clue they find after the incident that happened to the orphanage. The three of them managed to solve the mystery by becoming members of an adventurer's guild. They hope to find the figure of their parents soon.

Many obstacles stand in the way of each of the three twins' adventures. Even so, the three of them also found many friends and foes that made them grow even more. This made the three twins seem to have high hopes for meeting their parents.

Will these 3 twins succeed in knowing and finding the figure of their biological parents? Could it be that the three of them are children created from the relationship of God, Devil, and Human figures?
