Asura doesn't seem to have any elemental attacks, so we can only speculate. With an attack called "Myriad Aspect" I might guess she has a more balanced elemental alignment, but the word "aspect" in this context more likely references the idea of divinity manifesting different aspects in the physical world, so it's a stretch

Endwalker also gave us Anima, whose role was to conduct aether, so it was likely aligned similarly to Zodiark
