in the case of yukiatsu, dressing like her was a way to get back at jintan for "his menma" and the fact that he never got over his feelings for her. we see with anaru she lets people change her (evident with her changing her clothes to go out), so maybe menma had an effect on her and how she looked.

Obito took the alias of Tobi, and acted like the swirled-face, goofy Zetsu, by acting the same way, having that notorious swirled-mask, and, of course, bearing the same name. So, technically, no, they aren't.

Those developer notes do not mention Sigurd being related to Marth; heck, they don't mention Marth at all. The link made between the two series is that Jugdral takes place long before Akaneia (and that the Falchion, Aura tome, and Jugdral holy weapons are all somehow Dragonstones, what?).
