Chihiro Ayagi, a 24-year-old actor with Japan Arts Enterprise, stands 180 cm tall and weighs 63 kg. He possesses light brown hair, golden brown eyes, and a distinctive beauty mark below his lower lip; his blood type is B. Prior to entering entertainment, he worked as a university bartender. His acting career launched after he seduced a female producer visiting the bar, securing him an introduction to a prominent talent agency. This opportunistic entry fueled persistent rumors that his advancement relied on casting couch tactics and leveraging relationships. He debuted concurrently with Junta Azumaya and holds three years of industry experience.

Outwardly charming and accommodating, Chihiro's personality masks deeply manipulative and self-serving motives. He meticulously adapts his behavior to match others' expectations, projecting friendliness and care solely for personal advantage. This superficial charm veils a cynical worldview and a preference for navigating life with minimal effort. His actions and expressions often display a calculated carelessness, reflecting a disregard for genuine emotional connection. Professionally, he admits to using pillow talk to climb the industry ranks.

His key relationships revolve around rivalry and unrequited obsession. After co-starring with Takato Saijō in "The Red Leaf Ogre," Chihiro developed a fixation. Following a joint drinking session, he exploited Takato's intoxication to initiate physical intimacy, leaving a mark but stopping upon realizing Takato's involvement with another. Despite repeated rejections, Chihiro persistently pursues Takato, asserting his superiority over Junta Azumaya as a match. This incident cemented Junta's intense dislike, creating lasting hostility. During a confrontation, Chihiro inadvertently confessed his history of leveraging intimate relationships for career gain, which Junta secretly recorded. This recording now deters Chihiro's advances toward Takato. He also harbors animosity toward Ryō Narumiya, dismissing him as an irritating, clumsy, and childish brat.

Beneath his manipulative tactics, Chihiro's motivations reveal unexpected complexity. While primarily driven by selfish ambition, his obsession with Takato evolved into a genuine, albeit possessive, affection. He demonstrates a willingness to sacrifice his own career for Takato's happiness, indicating a capacity for selflessness that conflicts starkly with his opportunistic nature. This duality positions him as an antagonistic yet multifaceted figure, driven by both ambition and authentic, if distorted, emotional investment.
