I'm guessing E.N.D's curse is hell fire; in some fictional verses hell fire acts as a portal to hell (sends whatever it destroys into hell) such a portal would be a hole in space-time and therefore exempt from changes to ordinary space time such as age seal. But as we all know hiro is to stupid to even state how any of the powers work and by extension their potential capabilities, uses, strengths and weaknesses.
