Mrs. Inui (信司の母) is Shinji 's young mother. She is young woman after her husband passed away nor her name is unknown. She was voiced by Yuuka Hirose.
It is implied that her late husband was a rally driver, and in the first episode of Final Stage, there was a flashback scene where her husband was rallying back in the day with a rally version of her current notchback AE86. However, it wasn't clear whether her (also Shinji's) AE86 is a different car from the one used by her late husband for rallying or the same car but later converted for daily use, but still retain most of its mechanical modification.
