Tsumugi Shiraui

Tsumugi Shiraui is a Gauna-human hybrid created by Kunato Developments to fight the Gauna. Similar in size to a Guardian but Gauna-like in appearance, she is an exceptionally capable combatant whose prowess is rivaled only by Nagate's. She befriends Nagate and Izana and often interacts with them at their home using a tentacle threaded through the ventilation system while her main body remains in the hangar.
