Rei Hoomaru

Rei is Ragyō Kiryūin's secretary at Revocs Corporation. Rei is a young, dark-skinned woman with a light purple hair styled in locs. She always shows a very serious and professional front, though at times she seems comfortable making personal remarks about Ragyō, even as her underling. She also shows no objection to her boss's questionable character, due to the fact that she was saved and given a name by her. Source: Kill la Kill Wikia
