Chitanda is a calm and happy person, but can become very excited when new or interesting things happen, especially when it involves her club. She is described as a beautiful 16-year-old girl with long black hair and purple eyes. She usually sports a cheerful expression and is usually seen in her uniform.
She is the single daughter of the Chitanda Family, one of the four remaining wealthy farming families of the area, according to Satoshi. She joined the Classics Club due to “personal reasons,” and is the president of the club due to it not retaining any members from the previous year. She likes mysteries and has a great curiosity, which often drags Houtarou into solving them. She often expresses her curiosity with the phrase “Watashi kininarimasu!”, which is often translated as “I’m curious!”
