Okay, i've got a question i hope someone can answer me.

I thought Juggernaut Drive was suppose to give the user of Boosted Gear/Divine Dividing the full power of the Heavenly Dragon sealed inside.

Yet here we have it say that Cardinal Crimson Promotion and the Emperio Juggernaut OverDrive unleashes Issei and Vali's 'full potential at once.' Since these two versions are basically perfected Juggernaut Drive, that implies all these are in fact the inherent potential of Vali and Issei being forcefully brought out. Albion apparently has come to the conclusion that the God of the Bible didn't destroy their power, but sealed it. That means he believed their power was entirely gone before now, which lends credit to the idea that Juggernaut Drive isn't the power of the Heavenly Dragons but that of the user.

So was i just wrong this entire time? Is Juggernaut Drive the power of the Heavenly Dragons or the max potential power of Issei and Vali?
