Anyway I'm going to like this character... A crime-fighting magical girl. :D
Els here is acting as the announcer in the DSAA Inter-Middle fighting tournament that's going on in ViVid. She's a Barrier Mage like Yuuno, but as the other fighters have proven, she's not nearly as capable with her binds as he is.
She should learn about being a Rule Master from Freed (Fairy Tail).
A prominent binding and chain-magic user who wield a restriction type device "Punisher". Her battle style`s skills gained her a nick-name "Rule Master", her battle style oriented on seizing enemy`s movements and force him to give up. School president use the same techniques in the school to restrain students.
