Orochimaru's Wife

Orochimaru is one the greatest Sannin in the Shinobi World but after that war against Kaguya, Orichimaru's path was changed and what is most shocking there is that he already have a son who was team up with Boruto, Naruto's son. We are all wondering why or who is Orochimaru's wife but we should take note that Orochimaru has a lot of experiment, maybe his child is also one of his experiment but we cannot judge, Orochimaru changed after that war maybe she fell in love with one of his staffs or experiments as well (lol). Whoever the wife of this legendary sannin, would be a great and interesting that we need to wait to be published by the author of this anime.
