Saya Sasamiya

Saya is a drowsy-seeming girl, but is much more sharp and intelligent than she initially appears. She has a terrible sense of direction though. Saya is Ayato's childhood friend, though they lost contact when Saya's family moved to Munich, Germany. Saya's father is a meteoric engineering researcher, who designs and builds Luxes (mostly gun-type weapons) for Saya to use in battle
