It's a bit more different than that, Yuu's black wing is his wings, the only reason they're like that is because yes you were right because of Asuramaru. Asu is repressing the angel's full power so that Yuu doesn't get fully controlled by the angel or else he wouldn't be able to get control of himself back.. They're the same 'form' just one is incomplete and the other is complete, his incomplete form is the more 'messy' one, with Yuu's clothes being torn and such. Sorry if this doesn't make sense it's 1 am and I'm tired TL;DR: Asuramaru is stopping the angels full power to stop Yuu from never being able to get control back
