Demongodol requires you to send 1 of your monster and paying 2 gauge to call. I'm assuming when you call Demongodol, you can put Succubus to the drop zone. Succubus then activates her soulguard and she remains in the field, however Demongodol's cost becomes paid due to Succubus supposedly going to the drop zone.

In other words Succubus' soul can be used to be a payment for Demongodol's "Put a monster on your field into the drop zone" clause. Or at least thats what I understand.
