For a Normal Sacred Gear - User relationship this would be true....but that is NOT the case for Sairaorg. He was neither born with Regulus Nemea nor did he Steal the Sacred Gear like Raynare did it with Asias Sacred Gear. He Made Regulus, who manifastated himself after his Host was killed, and made him his Pawn !

Like I said because of his high Affinity to Lions he can use Regulus in a way like a Sacred Gear, but is it not like a Normal Sacred Gear  to User Relationship. Thats why I dont think he can reach Abyss Side.

Maybe Ishibumi proofs me wrong, but until he did that .....
