Description
Tsukasa Yuzaki, born Tsukasa Tsukuyomi, emerges as an enigmatic figure shrouded in centuries of secrets. Her path collides with Nasa Yuzaki’s life during a near-fatal truck collision, where she rescues him and unexpectedly accepts his impromptu marriage proposal on the condition they wed immediately. Her striking appearance features cascading pink hair secured with a delicate barrette and captivating red-pink eyes. She harmonizes refined aesthetics with functional comfort through outfits like her signature ensemble—a crisp white blouse, black mini-skirt, and pink socks—while favoring contemporary loungewear featuring bold purple stripes at home.

Her existence intertwines with the Princess Kaguya legend, later revealed as descending directly from the folktale’s celestial lineage. A consumed immortality elixir halts her aging process, granting ageless existence spanning fourteen centuries. This eternal life manifests rapid cellular regeneration that mends fatal wounds, immunity to illness, and survival through eras marked by warfare and technological revolutions. Her crimson fluid carries miraculous restorative qualities, once triggering relentless persecution from those coveting its power across generations.

Initially projecting detached composure, Tsukasa gradually unveils emotional layers, her guarded demeanor melting during tender moments with Nasa. She sparks visible jealousy when other women like Aya Arisugawa intrude on their dynamic, yet balances this intensity with a passionate consumption of modern media—binge-watching films, analyzing pop culture, and mastering video games. Millennia of accumulated wisdom surface through anecdotes recounting historical epochs as lived memories, complemented by expertise in traditional arts like katana combat.

What begins as a pragmatic union blossoms into authentic devotion as Tsukasa navigates matrimony’s complexities, championing fiscal responsibility while fostering closeness through domestic rituals. Despite her undying nature, she yearns for shared mortality’s ordinary rhythms with Nasa. Relationships with figures like adoptive sister Chitose and bathhouse overseer Kaname illustrate her capacity to nurture bonds, bridging ancient mysteries with contemporary connections.

Pivotal arcs trace her strategic unveiling of immortal truths to Nasa, their partnership in navigating eternal coexistence’s challenges, and veiled hints of her fingerprints on history—including subtle influence over Apollo program pioneers. Expanded backstory chapters expose cycles of trauma: centuries of hunters targeting her miraculous biology forged resilient compassion through survival, shaping her duality of cautious restraint and profound empathy.
