Sai Nanami is a calm, logical person who struggles a bit with social situations. She tends to take everything literally and gets easily frustrated when things don't go as planned. Even so, she is obedient, curious, and very expressive when she panics or is surprised. Sai Nanami is usually more notable for her expression and nervous/logical demeanor than for a striking appearance. Her design is quite simple to highlight her analytical personality and her role within the science group.
