Mei and Kii watching over Dolly and Kouzaku during the Jailbreak Trial.

Mei and Kii were tasked by Shokuhou with watching over Dolly as she and Kouzaku Mitori were participating in the Jailbreak Trial, given orders beforehand and their memories to be altered afterwards. Having unsubtly aided the two during the event, they were approached and thanked by Kouzaku during post-trial festival. While their programmed duty prevented them from asking about the girl who resembles Misaka Mikoto, they were still very curious about her identity and hoped that Kouzaku might let something slip, even if they would forget it, to no avail.[8]

Wild Speed

Mei using Wild Speed to reach top speed without acceleration.

Mei's esper ability is Wild Speed (捨象加速ワイルドスピード Shashō Kasoku (Wairudo Supīdo)?, lit. "Abstract Acceleration"), which allows her to instantly reach top speed without the process of acceleration. As a result, she can move fast and every other action packs more of a punch. It is hard on her body, but her flexible muscles can redirect the force.[1] As a student of Tokiwadai Middle School, it can be presumed to be at Level 3 or 4.
