It's likely an intended mystery on both ends.

The Demon of Gluttony also knew of H&G and mentioned them to Banica before her death, though this extended knowledge about "becoming" the MotG and needing (or at least perceiving a need for) H&G to do so was not included in the light novel.

On the other end, we don't understand what exactly the "Soul of Adam" entails, whether it be literal reincarnation or just Gammon's suggestion of a wish/will Adam had somehow before (or possibly after) his death.

It's quite possible Irina told Banica during one of their numerous encounters, though that would add more questions to the subject.

We may get more details in the heavily hinted Five the Pierrot installment, since Lemy is supposed to have some sort of interaction with Banica by the time he's dead.
