Non-legacy Omni units does not need Legend Stone to evolve.

Sirius was Legacy unit, I mean he's one of the older unit that received Omni form (like Elza, Alice or Zelnite in the future), yes of course Legacy units does requires a Legend Stone. xD

Yes that's it. I summoned like crazy before, even using my saved-up Gems and Summon Tickets (from Brave Point ones). Although it was 3-gem cost but the rates actually pretty bad, I suppose it was because of Azurai and Zelnite made me blindly summon for them without calculating first. :(
