Main Characters



 * He is a young scientist that was able to awaken the power of his mysterious Black Apple. To find out about his unknown past, Heidi joins the White Joker organization alongside his assistant Chitose Toriiooji. He is called by Nacht, his older brother, and the only person that Heidi recalls from his past's memories.


 * Equipment and Abilities:
 * Newtonian Apple: Being an Eureka adapter, Heidi is able to use these items, and the one of them that's in his possession is the Newtonian Apple, which grants him access over the ability to manipulate gravity.


 * Gravity Manipulation: When the Apple has its juice drank by an adapter, it grants them the knowledge about the Universal Gravitation, that consists in the principle that every point mass attracts every other point mass. The powers obtained when it's eaten by an adapter are therefore related to this law, as the user can control attraction forces and their several aspects in a certain area and between the bodies contained therein. As gravitational force is a physical quantity that depends on the masses and distance between bodies, and these aren't changed by the user when using his powers, it can be assumed that their nature consist in the abrupt alteration of the Gravitational constant in the area affected.

 * Genetic Mutation: It is implied that the Peas can grant an adapter the knowledge about genetics mainly surrounding the theory of Mendelian Inheritance. The power obtained when one of these Pea is swallowed, therefore, relates to this science, as the user can genetically mutate the genetic code of the eater's cells instantaneously.
