Tsumugi Shiraui  

, 白羽衣 つむぎ

A hybrid between humans and Gaunas, developed by Kunato Developments for combat against them. She resembles a guardian in size and appearance but has features similar to those of Gaunas. Her fighting skills are comparable only to Nagates, making her one of the most powerful fighters among humans. Tsumugi forms close friendships with Nagate and Izana, often interacting with them at their home through a tentacle that she slips past the ventilation system while keeping her main body in her hangar. It is later discovered that Tsumugi was created from a sample of a Gauna mixed with Hoshijiros DNA.
