Ikoma Kitsuno, a Warring States era concubine of Oda Nobunaga, reemerges in the modern world through time travel after her death at 29, now inhabiting a youthful guise. Retaining vivid memories of her life up to 1566, she wields the uncanny ability to trace ancestral bonds and discern souls historically tied to Nobunaga.

Fiercely possessive of the modern teacher she claims as Nobunaga’s reincarnation, Kitsuno harbors obsessive romantic and sexual devotion, prone to yandere outbursts when sensing rivals. Yet she navigates complex alliances with figures like Saitō Kichō—Nobunaga’s former betrothed—baltaining rivalry with calculated civility.

Her rebirth was triggered by contact with Nobunaga-linked pottery, anchoring her to the present. Strategically aligning with descendants of historical figures, including Mayu Biwajima and Yuri Hoshigaoka (whose souls echo Nobunaga’s past concubines), she merges feudal loyalty with modern social maneuvering.

Kitsuno’s journey centers on reconciling her 16th-century identity with contemporary existence, leveraging her intimate knowledge of Nobunaga’s legacy to bridge eras. Though driven by an unwavering quest for romantic claim, she reveals nuanced strategy and emotional depth, sustaining rivalries through shrewd cooperation rather than outright conflict.
