Some of the translations Vulpini posted are wrong, didn't even mention's Bolt's abilities for his technique. Although I'm not surprised at that one, honestly.
The stats seem to be wrong too, one of her's says Genjutsu and it's ranked with four stars. Meaning she probably has the affinity like Sakura, but I can't be too sure. Instead in the OP it's based on evasive, melee, and something else? lol...
To answer your question, the technique comes from the video game I think? She channels lightning into her weapons and throws them. However most of the abilities for each of them never made a real appearance in the Manga, even some are from the Novels (and like I mentioned video games). I don't really know how to approach this because we've never seen seen such disorder. If someone could translate them fully, we'd be able to pick at it a bit cleaner.
IDK.
