Chigusa Tsukikage, born Chizu, entered life as a penniless orphan, surviving among thieves until playwright Ichiren Ozaki discovered her at seven. He liberated her from destitution, integrating her into his theater troupe while cultivating her education in literacy, etiquette, and classical arts. By sixteen, her innate acting prowess secured her debut as Diana, the moon goddess—a role that earned her the stage name "Chigusa Tsukikage," evoking her haunting grace beneath moonlight.

Her stardom ascended through iconic performances: Ayaka in *Kaen* and the titular Crimson Goddess in *Kurenai Tennyo*, a part Ichiren penned exclusively for her. Amid World War II’s chaos, she stood by Ichiren as his theater faltered and family abandoned him. She shielded him from air raids, kindling a transient romance that shattered with his suicide. Inheriting *Kurenai Tennyo*, she pledged to resurrect the masterpiece.

A falling spotlight scarred her face, halting her acting career. Undeterred, she founded an acting academy, adopting mercilessly inventive techniques to forge prodigies. She identified Maya Kitajima’s untamed emotionality, pitting it against Ayumi Himekawa’s polished skill. To test their mettle, she staged a climactic duel in the Valley of Red Plum Trees, demanding they interpret *Kurenai Tennyo* excerpts.

Eisuke Hayami, Daito Entertainment’s scheming head, sought to seize *Kurenai Tennyo*, sabotaging her theater and exacerbating Ichiren’s collapse. Chigusa retaliated with strategic alliances, thwarting corporate predation. In her final years, she channeled fading vitality into mentoring Maya and Ayumi as joint heirs to the Crimson Goddess, believing their contrasting strengths could rekindle the play’s spirit.

Her trajectory—thief, star, mentor—mirrored relentless reinvention. Bonds of loyalty, rivalry, and pedagogy intertwined as she defended artistic heritage while sculpting its future, her scars and sacrifices etching legacy into every choice.
