Arixie (Aria Blaze x Trixie Lulamoon) doesn’t really seem like a popular ship to me. And I don’t blame you for that. I still ship Aria Blaze with Sunset Shimmer, etc. and Trixie with either Adagio Dazzle, Twilight or Starlight. But I think doing some edits with this ship would give it a little bit of love. Besides I saw my friend bigpurplemuppet99 do a fan art and made a stamp of the ship using a screencap from Rainbow Rocks.
