Pretty epic. But isn't Devasena Indra's daughter, not Vishnu's, or am I missing something?

Besides, unless it was some sort of blessing deal, where Kartikeya and Devasena blessed Ise's parents with Ise, its very unlikely. Volume 20 had a whole scene where the parents remember Ise's mother pregnancy with Ise and his birth from his mother, Ise's mother is his birth mother.
