Mrs. Uesugi is the late wife of Isanari Uesugi and the mother of Fuutarou Uesugi and Raiha Uesugi.


  • Mrs. Uesugi's portrait shares a great resemblance with Rena Nakano (the Nakano Quintuplets's mother).
    • It is unknown whether this is a decision by the author.
  • Not much is known about Mrs. Uesugi as she passed away prior before the events of the series.
