Coralie Planck

1

Coralie 6626 Planck is an Anti-Entropy member sent out on a Mars expedition alongside Erdős Helia of Schicksal. Coralie was born with dog body parts and her physical development stopped prematurely due to Honkai's influence. Einstein, Tesla and Welt played a guessing game to decide who would adopt Coralie. As Einstein being the winner, she was declared as her adoptive mother. Even though she prefers being referred as sister by Coralie, she feels lucky to be her guardian. In fact, she gave Coralie the last name of Emma Planck, a person so important to Einstein that fulfilled a role of a mother to her. When she turned 17 years old, Coralie achieved her doctoral degree, the same age Einstein did. At present, she's a member of the Mars exploration team along Erdős Helia.
