There's no mention of them being siblings in any of the official profiles I've looked at, English or Japanese.

However, watching through the English cutscenes of NiGHTS: Journey of Dreams, I found one instance of Reala calling NiGHTS "sibling". I've no idea if the Japanese version is the same. So that can be put back in.

But I've found absolutely nothing on Jackle being a "sibling", which is what caught my eye in the first place, since he's just an ordinary Level-2 Nightmaren boss character.
