Dr. Kieda's 10-year-old granddaughter. She is gentle, caring, erudite and resourceful. She misses her grandfather dearly, thus earning a lot of sympathy from the rest of the team. She might seem a little cry-babyish at the first glance, but vows to become stronger under the influence of Tanpei, who she has a crush on. Her name is derived from Junko Sakurada, a famous Japanese singer.
