sen is walking around in a park in Mitakihara City when they see a tiny creature chomping on a piece of cheese. It was Nagisa Momoe, though she was currently in her witch form, "Bebe". Bebe looks up at sen and starts making noises that could only be defined as “Bebe noises”. “Mun-chee chee Camembert! Be-be~!” The little witch says, to the confusion of sen. Her words came out as gibberish. Though before sen could say anything else, Bebe spoke up and said something else. "Parmigiano Reggiano!" After saying these words, a soft whistle came from Bebe. "Parmigiano Reggiano" happened to be a keyword for Bebe, which allowed her to transform between her witch and human forms.
When the transformation was finished, the tiny witch Bebe became Nagisa, having an embarrassed expression on her face after sen saw her. "Ehehe..." Nagisa Momoe nervously giggled. "I apologize for that, I was just enjoying some cheese." She sheepishly said, her gaze drifting off to the side slightly. "It seems like I got too carried away... Parmesan is my favorite cheese..."
