Devilgan? Not sure what to think about that, or the clan's seeming to think they have a more powerful dojutsu than Sharingan. Unless of course hellfire > Amaterasu and whatever the genjutsu is > Tsukuyomi/Izanagi/Izanami.

Also, just a note: Shadow Clone Jutsu by itself is a B-Rank, so a Fire Release shadow clone would be at least B to A Rank, not C. :gray
