Do outfits provide stat bonuses?

So outfit choice is a pure look decision. There is no defensive set, no hidden bonus stitched into a rare piece, and nothing to hold back for later. Whatever you think looks best on your character is also the correct choice mechanically, because every option performs identically.

That matters most if you came looking for where the numbers live. In Aniimo they sit on the creatures, not on the human. Each Aniimo brings its own physical traversal ability while twining, and those are what change how you move through the world: sprinting, climbing vertical walls, swimming, diving, gliding, flying, and burrowing underground. Team power works the same way. Prismana Turbo has an exclusive Dark-type support skill that feeds Dark damage support to the rest of the team. Nothing your character is wearing touches any of that.

So when you plan a run, plan around which Aniimo you are carrying. The wardrobe is not part of the build.

Premium outfits and pre-order bundles

Premium outfits are gender-locked, with distinct designs for male and female characters. A design you like may not exist for the character you made, and since the outfit does nothing for your stats, that limit costs you appearance only.

Pre-order bundles and extended editions are a separate matter. Those provide starting items and bonuses, which is real early-game material rather than decoration. Keep the two apart in your head: a bundle can change how you start, an outfit changes how you look.
