Sara's a well-known Asakusa idol who does news reporting, and she's got that energetic, bubbly personality that makes her pop on screen. But there's a flip side—she's pretty spacey and forgetful, almost to the point where getting kidnapped or locked up doesn't really faze her. She comes across as a bit clumsy, though it's hard not to like her because she's genuinely good-natured.
What's interesting about her role in the series is how she functions as a running commentary. Like the Shadow Players from Revolutionary Girl Utena or Double H in Penguindrum, Sara essentially serves as the show's Greek chorus, stepping in to offer allegorical takes on whatever's happening in each episode. It's a clever bit of storytelling that sets her apart from just being comic relief.
