Chiaki Matsushita (
Chiaki is a teenage girl of average height with long brown hair that has bangs swept to the right and blue eyes.
Her personality is not explored in depth but from what is gathered throughout the Light Novel, she has a quiet older sister type of personality. Chiaki is generally kind to all the boys and girls alike, but does not actively go out to make friends.
Chiaki determined early on in the first year that Class D had no hopes of ever reaching Class A and thus resigned herself to a carefree school life, never putting in any real effort into her academics. She considers herself to be a major underachiever, thinking that she could easily score in the top 10% of her class if she applied herself, but believed it to be pointless as long as she was in Class D. Later on in the story, she starts seeing improvements to the class and becomes willing to start applying herself. She is also known to be skilled at mental arithmetic and can calculate quickly. She even held her own against Kōhei Katsuragi from Class A in a Mental Arithmetic exam in Volume 11.
- The name Chiaki means "thousand" (千) (chi) and "autumn" (秋) (aki).
- Chiaki's surname Matsushita means "pine tree, fir tree" (松) (matsu) and "under, below" (下) (shita).
- As D-Class is for those with flaws, Chiaki’s flaw is her distant behavior.
