Ren Jingūji stands tall with strawberry-blond hair, light blue eyes, and fawn-tanned skin, his playful wardrobe mirroring a flirtatious charm. A discreet pierced ear—shared with Syo Kurusu—peeks beneath strands concealing his right side. Born on Valentine’s Day, his Aquarius spirit fuels a free-spirited defiance against conformity, rejecting limits on freedom.

Third in line to the wealthy Jingūji legacy, Ren escaped the burdens shouldered by his elder brothers, nurturing a carefree indifference that colored his early idol career. Reluctantly enrolled at Saotome Academy by his eldest brother to advance family interests, he initially rebelled despite a buried passion for music. Childhood tragedy shadowed him: his mother, a former idol, perished in an accident, and his grief-stricken father erased all traces of her existence. Ren salvaged a single demo CD she recorded for him, a fragile relic that anchors his musical identity.

Charming and mischievous, Ren delights in teasing Masato Hijirikawa, his straitlaced childhood friend and roommate, their dynamic a clash of formality and irreverence. Though adept at charming admirers, his encounters with Haruka Nanami unravel his detached facade. Her presence reignites his purpose, transforming perfunctory performances into heartfelt artistry. While his playful flirtations linger, they now intertwine with unwavering loyalty to Haruka, whom he dubs “little lamb” and “my lady.”

Connections deepen through bonds with Ranmaru Kurosaki, another lifelong friend, and camaraderie among ST☆RISH members. Behind his lighthearted exterior lies unexpected gravity, surfacing when allies face strife. A childhood chocolate-related trauma fuels his aversion to sweets, starkly contrasting his Valentine’s birthdate.

A saxophone virtuoso with fluent Italian, Ren navigates a path merging familial duty and personal ambition. His journey weaves past nonchalance with present resolve, harmonizing artistry, kinship, and rediscovered passion into a life less ordinary.
