Koyori Hakui handles R&D for Secret Society holoX, though "in charge" might be generous given her actual track record. She's got this thing about studying human behavior, which mostly means she's constantly poking her nose into what the other members are doing—sometimes to genuinely help, sometimes just to see what happens when she pushes their buttons. She calls herself the "brains of the operation," which is funny because her actual expertise is. pretty scattered. Still, she's got that unstoppable drive to learn about everything, even if it means making things awkward just to observe the results. The curiosity thing isn't really an act with her—it's genuine, even when it tips over into meddling.
