Renka Ephilty

Renka Ephilty (＝エフェルティ) is a maid serving Resanerié Sadis Dialine, as well as a student and debate representative of a School Garden school.

Appearance
While acting as a servant to Resanerié Sadis Dialine, Renka wears a maid uniform. She also has hard plastic extensions in her hair.

Background
Initially Renka was apparently an ordinary girl, but would come into the service of Resanerié Sadis Dialine, along with Tougyo Kea, Sanki Ai and Shitatsuzumi Yoshiko, with Renka acting as Resanerié's maid. The five attended separate schools in School Garden and became the debate representative for their respective schools.

On the day of the entrance exams, she and the other debate representatives supported Resanerié as she executed her plot to take School Garden into the skies and make it independent from Academy City under her control.

Abilities
Renka's ability is Level 3 Fly Racing, which allows her to control hard plastics (such as extensions in her hair and wires keeping the shape of her maid uniform) to form giant ground effect wings, allowing her to glide forward at high speeds. Although the ability is apparently inefficient and has various problems, she can utilize it very quickly, moving from a standstill to a high speed glide less than a meter off the ground with a single step. Her maximum gliding speed is 1100km/h.
