Beyblade Burst Competitive Combos List & Public Discussion [TENTATIVE]

Guys, I just saw this video. I don't understand Japanese or whatever language this video uses. Is it a video about how to launch and also to 'awaken' volcanic drivers?

Saw this just now too:

Is it just another way of awakening the volcanic' drivers? It looks like it to me because in the 1st launch, it is aggressive, then in the 2nd and 3rd test launches (not real life 2nd and 3rd test launch. I mean 2nd and 3rd test launch that he shows) it is calmer. Can anyone translate the text shown in the last 2 battles?
