Princess Shokushi, or Shokushi-naishinnō, was a Japanese classical poet of the late Heian and early Kamakura periods. Her work, notably poem No. 89 in Fujiwara no Teika’s *Hyakunin Isshu*, showcases emotional intensity and refined artistry. She possessed dark purple eyes and a cascade of chestnut-brown hair reaching past her hips to her feet, often adorned in layered court robes reminiscent of a junihitoe, emblematic of aristocratic women of her era.

Her temperament intertwined solitude, spiritual depth, and quiet strength, forged through personal trials and bonds. She shared a profound intellectual kinship with Fujiwara no Shunzei and his son Teika, the latter linked to whispers of unrequited affection, revealing her undercurrents of yearning and fragility. In exchanges with Shunzei, she advocated for Teika’s creative growth, urging their collaboration to ignite his poetic potential.

Poetry served as her sanctuary and voice, encapsulated in her entreaty to Teika: "Make-believe love is all I have... Only poetry can liberate me from the prison I live in"—a testament to her art as both escape and assertion amid life’s confines.

Historical accounts mark her death in 1201 at age 52, with slight variations on the precise date. Her demise, portrayed in the series, mirrors the poignant closure of a life steeped in reflection and enduring literary legacy.
