Chelsea Rorec チェルシー・ローレック

Chelsea is Ruri's bodyguard/tutor, and accompanies her when escaping from the Underground. Chelsea controls powers related to gravity, and has a personality to match. She is very dedicated to her task of protecting Ruri, and would gladly lay down her life - in fact she spends much of the early episodes bashing Rumina on the head for being too familiar with Ruri. Chelsea's gravity-power is very strong, and she is a tough opponent. She always argues with Rumina and always gets into a fight with each other, however she later respects him and developed feelings for him.
