Exactly take Sairaorg for an example, he was cut with a Holy Sword, he didn't die. Yeah in Sairaorg's case he was wearing his Touki and Sairaorg is different than most Devil. But like previously mentioned, Devils with sufficient Demonic Powers could negate the effect of light to a certain extent. Holy Energy is made out of light. And for Super Devils that greatly surpass the usual amount of Demonic Power that a Devil has, even if a Holy Sword is used to attack Rizevim, it probably could only give him some minor wounds at best. But that depends to be seen for now.
