It's also possible that more interest will arise once the anime starts.
If you hadn't heard this fall they're doing a full season (seems 26 episodes) of it.
Looks to be the same as the OVA if you saw it. If not, Yuno is covered by Murata Tomosa, a relatively unknown VA as far as I can tell. Her only other role was in Densetsu no Yuusha no Densetsu as Eris, Iris. Minene Uryuu is covered by Aizawa Mai apparently, a somewhat more seasoned VA who also voices Mia from Nichijou and a few other mostly supporting roles.
Oh and it's produced by Asread, who also produced Ga-rei zero. Good show too.
