From kindergarten to grade school, Izumi braids her hair in twin-tail style. Afterwards, in middle school, she switches down to pigtails.
She has an energetic upbeat similar to her parents. Her baseball passion stemmed after watching her Dad's return match to the Oceans.
Izumi was born in America during Goro's 8th year in the Majors after winning the world series. She moved with her family back to Japan after Goro was retired from the US. She disliked her dad for being a jobless deadbeat since he returned, but was uplifted after Kaoru took the kids to her dad's return match where she received her Dad's message from his homerun batting. She joined the Mifune Little afterwards for the rest of her elementary school life.
Izumi advances on to Fuurin to high school, advancing in both sports and studies while continuing baseball. She begins to worry for her little brother, Daigo for being lethargic about his complexity against his father. Izumi was relieved to her Daigo continuing baseball after deciding to become catcher and supports him with her little league experience.
- In the anime, she serves as Fuurin's ace.
