Trivia

 * Mrs. Uesugi's portrait shares a great resemblance with Rena Nakano (the Nakano Quintuplets's late mother) except the difference in hair color.
 * 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 when Futaro was six years old.
