Seeing as how Kitani's adopted daughters go to a magic school, you'd think Terry would know not to read incantations out of mysterious books she finds around said school... But since she was dressing up as Nekozawa, president of the Black Magic Club, she needed something spooky and arcane to complete the look. There's a fine line between "cosplayer" and "weirdo with a hand-puppet," ya know.
So she read from the Lolinomicon, and the nearby Kitani got caught up in the spell. Loli-Kit was so distraught that she took the book from Terry and... had Gabriella learn the lolification spell. By heart. >.>
