If Kingdom Hearts was darker and much more "metal" whilst being much less "establishment"=This!
PS: I just noticed the heart looking motif on the armor but to be frank I think your aversion to KH shows you have good tastes. I remember digging KH1-2 back in the day and Birth By Sleep on my PSP but the storyline by then was already becoming overly convoluted. (Especially for what should be a rather straight forward cross-over fan game) I'm no fan of what Disney has become lately. Lastly I preferred Square more before they merged with Enix but that is a whole other can of worms....
