Extraction: Black Water that Changes the Ways of the World

Yuuma Toutetsu's Spell Card. She extracts the power of crude oil in this attack. There were once two theories regarding the origin of oil. One that said its origin lay in organic life, while the other said it lay in inorganic gas produced by the Earth. Eventually, the organic life theory gained wide support, with the formation of kerogen being seen as a critical step in oil's production. The theory states that the remains of creatures from long ago amassed underwater, where they carbonized. Then, due to the Earth's heat and pressure, they transformed into oil. In that sense, oil is nothing more than a concentrated solution of the dead's resentment and vengeful thoughts.
