Maou Dante

Different theme but there are some similarity. However when I watched them I felt Shinji and Ryo's action where similar also their fathers in some ways. The ending in Maou Dante is almost same as NGE: The End of Evangelion. Some of the romance may be same too.
As NGE use mechas/Angels, Maou Dante also have some kind of huge alien/monsters or "Demons".
