Taiga Aisaka

The other title character of the series, Taiga is a girl in Ryuji's class, and sometimes acts like a tsundere when talking to him. She has a beautiful appearance, but dislikes the company of others, with the exception of her best friend Minori Kushieda. Because of her tendency to snap fiercely at others, and because of her diminutive stature (4 feet 8 inches in manga, 4 feet 7 inches in anime), Taiga's nickname is "Palmtop Tiger" (???????, Te Nori Taig?). She often receives confessions of love from boys due to her cute, or as Ryuji puts it, "doll-like" appearance, but she turns down every single one.
