it's derivative in premise, but different enough to succeed and co-exist with dxd to the point of me and a lot of other people not really caring about the similarities.

i used to write off shinmai as a poor mans dxd until i got into it to give it a fair opinion, and even though i still prefer dxd, shinmai is quite good as well and has noticeable differences that set it apart from dxd.
