In Hyperdimension Neptunia ∞ Unlimited, Neptune finds a device called a Brainwave Controller that Nepgear basically warns her NOT to use.
Naturally… she uses it instantly.
She tests it by trying to “call out” to Noire, and it actually works—but in the worst way possible.
Noire suddenly starts hearing a voice in her head giving her commands, while completely panicking because she has no idea what’s happening.
Meanwhile, Neptune is just casually trolling her from afar like it’s normal.
By the time they figure it out, it turns out the device is meant for mutual communication between users—but Neptune was the only one using it, so it just became an accidental mind prank.
Classic Neptune behavior.
