Oooooh, nice one Toua! Lots of interesting informations, for example the main cast:
Ein: Takagaki Ayahi (Noe from True Tears)
Zwei: Irino Miyu (Saji Crossroad from Gundam 00)
Cal: Sawashiro Miyuki (Tsugumi from Kannagi)
Claudia McCullum: Hisakawa Aya (Skuld from A!MG
- well, more like Natsume Maya from Tenjou Tenge)
Lizzy: Watanabe Akeno (Tiamat from Shakugan no Shana - Wilhelmina's contractor)
No voice for Mio yet, but she's clearly shown in one of the screenies, so we'll obviously get the full story of all three chapters this time (thank god!)
