Sasaki

Sasaki is the chief engineer of Toha Heavy Industries and the chief Guardian mechanic. While not a main character, Sasaki is certainly important on board Sidonia. As the Chief Engineers of Toha Heavy Industries, her job onboard the ship is to maintain the Guardians. She also upgrades and enhances the Guardians, such as developing a new rear unit engine, and the prototype railgun for the artificial kabi bullets. Sasaki seems to wear a skin suit similar to those the Garde pilots, but it had many small pockets to hold little pieces of gear. Her hair is tied up in a hefty pony tail, but with ample hair hanging over her ears. Her right eye is completely hidden by her hair, leading some viewers to think she lost that eye, but very brief glances reveal her right eye is intact. Sasaki is already taller than most of the Sidonia's cadets and other crew members, but with her temper taken into consideration as well, she can be somewhat intimidating at times. She wears a pair of goggles over her forehead, which she is never seen using, as well as a hefty wrench on her right hip. Sasaki is generally relaxed, but can be hot-headed. She has shown to be very proud of her Guardians and other machinery, and as such, she is also protective. In spite of her Gardes being used in combat regularly, she is often upset at the condition the Gardes come back in, particularly the Tsugumori. When Nagate is given ownership of the legendary Garde, she threatens that if it comes back damaged that she would punch him out. Later, when Nagate tells her about using the prototype railgun in his training simulator, she assumed he was lying and got in his face.
