Teru Miyanaga

Teru is a third year student at Shiraitodai High School. Teru is Saki's older sister, who went to live with her mother when their parents separated. She has since become a powerful mahjong player, rumored to display fearsome powers. She used to play with Saki Miyanaga and the rest of the family when they were younger. Saki dreams of progressing to the nationals and finally reuniting with her, but Teru denies her existence. It is still unknown as to why she is mad at Saki. Teru and Shiraitodai have won the past two individual and national team tournaments, and aim to repeat both wins this year.
