Main Characters

 * Heidi (ハイジ)


 * 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 Barschheit (バルシュハイト) 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.


 * Chitose Toriiooji (鳥居大路千歳（トリーオージ チトセ）)


 * She is an university student and the part-time assistant of the young scientist Heidi. She follows her instructor by joining the UN organization, White Joker, as his official assistant.


 * Killed (キルド)


 * The mysterious figure who introduces the existance of Eureka to Heidi. He is a member of the dark organization, Mavro. Additionally, he is also an Eureka-compatible individual who possesses the Mendelian Peas.


 * Equipment and Abilities:
 * Mendelian Peas: Being an Eureka-compatible individual, possesses one of the Eurekas called the Mendelian Peas. Through this particular Eureka, Killed is bestowed with the ability to manipulate humans' genes. Killed had already made various kinds of mutated creature while using the power of the Peas which he called his creation as "puppets".


 * 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. Normally, the user presses the pod to make a Pea to come out, subsequently eating it, feeding it to a previously modified creature, or throw it at a target's mouth, forcefully affecting it.


 * Anise
