I'm just going to say you are right for now. I've believed Juggernaut Drive is the power of the Heavenly Dragons until now. That's what almost every volume until now has implied. I shouldn't go questioning that until it is clearly stated. Plus, the choice of words can make a huge difference. Power and ability can be totally different despite being interchangeable a lot of the time. So i am just going to wait till we got a proper, full translation out. Not a quick summary where the person might not be choosing their words carefully.

Thanks for putting in the time to answering my question.
