A few weeks after his power surge, Sepphirothy managed to suppress 25% of Vergil's energy, creating a temporary valve to contain his uncontrolled growth. However, it was a fragile solution. Every day that Vergil spent without seeing her at night, his energy would completely restore itself. Or worse: it would exceed 115%, even with simple rest. ~His body, instead of stabilizing, returned to absolute pressure. An endless cycle, where resting was the same as overloading himself.
Worried, Sepphirothy suggested that he use the Blood Manipulation inherited from the Baal Clan to constantly increase his circulation during the time he was awake. The idea was simple: keep the energy flow active and, thus, better distribute the internal load. But the theory failed. Miserably.
