More info about the cast:
Honda Masazumi = Sawashiro Miyuki
Asama Tomo = Koshimizu Ami
Aoi Kimi = Saito Chiwa
Neito Mitotsudaira(?) = Inoue Marina
I was already happy with FukuJun as Toori (naked hentai main character) and Minorin as Horizon but with the addition of these seiyuus it just makes this more awesome even if 85~90% of the cast wasn't announced yet
. The first arc was one of my favorite in LNs and I really can't wait for october.
