No just no. Ishibumi already stated in Volume 1's afterword.

"Devils and Angels are the main theme, so during the story, names of those from myths and legend will appear, but this series is written where it won't be restricted by them.

In other words, the events written in the bible and non-fiction books are just used for references and the author, that is me, writes it freely with an original story.

Just think that the majority of things related to Angels and Devils are made up in D×D. Well, there’s no way that the word [Evil Pieces] will appear in the bible."
