He did this hundreds upon thousands of times, despite Eri's pain.Įri tried to escape and resist many times but to no avail and eventually accepted her fate as a prisoner. He did this by destroying Eri with his Quirk, collecting blood, and then repairing her. He manufactured them into bullets that are shot at a target and inject them with her blood. Through unknown means, he discovered that her blood had properties that suppress the bodies' ability to manifest 'Quirk Factor', inhibiting someone's Quirk.
