Chiaki is the youngest of the three siblings and still in elementary school, currently in class 5-2. She's got a sharp mind that tends to work overtime—she'll overthink pretty much anything, even stuff that doesn't really need it. While her older siblings Kana and Makoto do their thing, Chiaki mostly just ignores them when they're being ridiculous, which is often.
Despite being the youngest, she's definitely the meanest of the bunch. She's usually pretty quiet during group stuff, but when she does speak up, there's a good chance you'll hear her go off with "bakayarō"—basically a harder-hitting way to call someone an idiot than the milder "baka."
