Hohoho hahahahaha there was a Sultan who had like +2000 wives and like 10000 children - the sons served as his personal guard. But since we are on mythologies here then know this: Krishna the 9th avatar of Vishnu had 16108 wives and had 10 children with each of them. Oh and he could sleep with all of his wives at the same time.

So no Issei has a long way to go to the biggest harem ever.
