From the way that the translations are having them talk, if they are their kids then it seems like the kids hate Issei or all of their parents for some reason and want to kill either Issei or all them.

And another kids said that mother Asia would be saved. So they want to save Asia from something.

And one had a dragon wing and an angel wing which could mean that it is Issei and Irina's child. And they are praying to another god.
