KOS-MOS is an experimental android built by Vector Industries. She was built to be a weapon against the gnosis. Her A.I. is complex, though mainly designed for efficiency during combat, although it is possible to hold a proper conversation with her. She operates off of logic rather than emotion. KOS-MOS is from Xenosaga.

Satsuki Kiryuin is one of the main characters in the anime Kill la Kill. She has a cold and fierce personality, but will open up to anyone close to her.

Their names are Uzu, Nonon, Ira, and Houko. Satsuki wears her Kamui Godrobe, Junketsu, which can transform into a (very revealing) battleform, has a sword named Bakuzan.
