As far as i can tell, it was simply assumed to be a Kiba power. It's not a retcon if it was fanon all along. The Manga makes no real mention of it's power, just that it's imbued with lightning, making it the sharpest blade. Seems to me it's functionally similar to the Five Element Fan, in that it's imbued with an automatic nature transformation and can either use the user's chakra or (for master-wielders) gather energy from the environment.

Also, i'd forgotten how Raiga used it. He constantly channels lightning from the sky. Makes sense that in this boruto episode, it's inner power since we don't see her charge the blades even once. Raiga did it basically every other jutsu, if not every jutsu. He also didn't use any handsigns. Ncduru wrote: It's been a fucking minute since I've watched the Raiga arc... Naruto killed him by Rasengan? Naruto did a 300 on him and kicked him off a giant cliff. Raiga killed himself mid-flight to avoid the moral repercussions.
