"Cough, cough. There are still too many unknowns regarding what appeared in Seiya's body, so it's hard for me to make a judgment.
But based on the current situation, the Sacred Gear within Seiya definitely isn't the Blood of Omnipotence, but a more powerful Sacred Gear—possibly even a God-Slaying Tool.
