Shows which had their characters designed by Hirashi Hirai (Infinite Ryvius, Scryed, Gundam SEED, Soukyuu no Fafner) all pretty much look the same.
His designs are distinctive and I like them, but his range isn't great. Not that it should matter that much, Leiji Matsumoto's designs have looked all alike for decades.
But for this particular anime (i'll find out what it is later), they look EXACTLY alike. Like there's kira, there's ahtrun, there's freya etc. Not sure if it was intentional though. Its kinda new.
