Due to the fact, they were brought up from forbidden couples, the father being a half demon, and the mother as a regular human being.

Now there are organizations in other dimensions wanting the Manticore monster implanted in Hito's soul, and the angel essense(energy) found in his sister. on the contrary, the parents Dante and Ezria Vladins are on the assassination list, and the two kids have to find a way to avoid being captured by the Kros-Trigates clan.

Their soul purpose is stealing, and controlling the power sources in order to keep their lord alive by feeding him the essense from the Mystical monsters and Viruses.
