To be generous: Sairaorg CAN become Superdevil Level.

BUT he cannot do it with a new Evolution of his Sacred Gear. He can do it with Hard training. This will than enhanced by his Sacredf Gear. Since "Regulus Nemea" is NOT his Sacred Gear...connected to his Soul... he cannot reach a Abyss Side BB in theory. But he don´t need to....he had show already that his will and his Body is all he need...he only will need a little longer^^
