Juggernaut Drive

I asked Azazel-sensei this. Before Vali left, he tried to do something. Though Albion also tried to restrain him from doing it…

“Ah, that was the [Juggernaut Drive].”

“Is it something above even the Balance Breaker?”

“No, there exists nothing above Balance Breaker. The ultimate and final form of Sacred Gears is the Balance Breaker. However, there are several things inside Sacred Gear that have a magical being sealed in them. A peculiar restraint is applied on those ones. Your Boosted Gear and Vali’s Divine Dividing are examples of that.”

I see. Mine and his Sacred Gears are the type whose power comes from having a magical being—in other words, a dragon - sealed inside it.

“Those ones are strongly restrained, taking out power while in that state and making sure that the host can use it. In the case of the Sacred Gears of the Sekiryuutei and the Hakuryuukou, forcing that restraint to temporarily release and unleashing the sealed power is the [Juggernaut Drive]. It temporarily gives one power rivalling that of God, but the risk is also huge. It greatly shaves off one’s lifespan. And it also makes one lose their sense of reason.”
