Regarding this popular belief, some would consider it is the reflection of the truth; Princess Kiku is known that she was truly adored by all in Uesugi clan, substantiated by the fact that she is favorably described in various references as a woman endowed with both beauty and intelligence, despite the fact she married into the Uesugi clan for political convenience; thus quite a few feudal retainers refused to admit the presence of the concubine Yotsutsuji near Kagekatsu.
この俗説に関しては、菊姫は政略結婚によって上杉家に嫁いだ女性にも関わらず、複数の史書に才色兼備を謳われている程、上杉家中一同の深い敬愛を集める存在であったと伝えられることから、四辻氏という女性の存在自体を認めたくない家臣などが少なからずいた可能性は否定できないとの説もある。
