The one in charge of R&D in Secret Society holoX.

- Koyori shares her illustrator with Petra Gurin of Nijisanji EN.
- Her greeting "konkoyo" appears to be a portmanteau of the standard Japanese greeting "konnichiwa" and her name Koyori. Similar greetings include Shirakami Fubuki's "kon kon kitsune" and Ceres Fauna's "konfauna."
- Her hexagonal hair pin represents a molecular diagram of a benzene ring, a constituent of petrochemicals.
