If you're wondering why the character art looks familiar, it's because the illustrator is none other than Noizi Ito, artist for Haruhi Suzumiya and Shakugan no Shana.
Not many details available right now, so if you’re interested at all in helping out and will have a costume from The Guided Fate Paradox (KamiParadox) by AX, please volunteer!
Limited to ACParadise cosplayers only with uploaded photos of their costumes on acparadise.com.
We’ll have more information as time passes
