Sorry I dont know the creator but this is shinra! Chocolate rice makeup (https://chocolaterice.booth.pm/items/4786368) and hair (https://chocolaterice.booth.pm/items/4804565) I think the pants are also chocolate rice (https://chocolaterice.booth.pm/items/4934527) just going off the belt on the leg.
