Sakura Ushikubo, heiress to the Ushikubo Medical Manufacturing Group, is a 16-year-old Kokusen Academy freshman with striking pink hair, emerald eyes, and a slender frame. Born December 14, her upbringing under a family creed valuing honesty and condemning deceit forged her staunch aversion to lies, drawing her to the candid Hikari Hanazono. Initially proposed as a match for Kei Takishima—whose talents promised strategic benefits for her family’s enterprise—she rejects him romantically, labeling him a “dark lord” rather than her idealized “prince.”

Her outlook transforms upon meeting Jun Yamamoto, whose demeanor and appearance mirror her romantic ideal. She swiftly falls for him, embracing his split personality without hesitation. Their bond evolves from Jun’s initial wariness of her boldness to a mutual confession of affection, blossoming into romance.

Sakura shares a dynamic rapport with classmate Yahiro Saiga, partnering on schemes spanning from constructive ventures to playful mischief, showcasing her strategic intellect and flair for intricate plots. Though assertive, she reveals vulnerability, doubting Jun’s feelings until he openly affirms them.

Rooted in her lineage, her pragmatic approach to relationships reflects the Ushikubo Group’s emphasis on integrity and shrewdness—qualities that initially framed Kei as a marital candidate, though her heart ultimately prioritizes personal yearning. Her surname, blending “ushi” (cow) and “kubo” (hollow), contrasts with “Sakura” (cherry blossom), emblems of resilience and transient beauty.

Her narrative navigates the tension between dynastic expectations and personal longing, evolving from strategic marital calculations to pursuing heartfelt bonds. She harmonizes bold assertiveness with emotional vulnerability, particularly in navigating Jun’s layered nature while nurturing mutual trust.
