It is explicitly said that what came out of Eve was the Demons of Sin.

Considering that the Sin arc blew up before Eve's death it is very possible that they escaped. It's impossible for them not to have left. It's possible they hitched a ride on Levia and Behemo's dragon body and were a part of the two lights that fell down into Held's forest.
