Saeko Tanaka

As the boisterous older sister of Ryuunosuke Tanaka, this former Karasuno High student shares her brother's loud and outspoken personality. While the volleyball team’s second years, particularly Nishinoya, admire her as a cool mentor figure, her brother often finds her interruptions during study sessions quite annoying. A classmate of the legendary Small Giant, she is also notorious for her reckless driving, a trait so intense that her brother warns guests they are never truly safe in her car.
