Description
Cliff Cay is a fifteen-year-old student from the anime Infinite Ryvius, who is officially assigned to the nursing section. Born on November 11, 2210, Cliff has a height of 177 centimeters and type B blood. At first glance, Cliff presents a strikingly feminine and alluring appearance, with a mature fashion sense, brown shoulder-length hair, and blue eyes. This appearance is so convincing that he is easily mistaken for a girl, a perception reinforced by a curvaceous figure that is the result of breast augmentation surgery. In reality, Cliff is biologically male and identifies as a newhalf.

Cliff is the older brother of Michelle Cay, another student on the ship, and the two share a complex bond shaped by a difficult past in the Saturn sphere before being taken in by the Blue faction. Where his sister is described as having a petite and somewhat sadistically charming personality, Cliff carries himself with a worldly and strategic edge. He is initially portrayed as someone who uses his good looks to his advantage, deliberately charming others for his own benefit and protection. Because of his beauty, many men have approached him, but the revelation of his true gender has always caused them to leave.

Cliffs role in the story becomes most significant through his relationship with a character named Charlie. He initially attempts to manipulate Charlie, intending to use him as a tool. However, when the two are pursued by other trainees, Charlie puts his own body on the line to protect Cliff. This act of selfless bravery deeply moves Cliff, who has likely never been accepted for who he truly is. Unlike all the others who fled upon learning his secret, Charlie loves Cliff in a way that transcends superficial boundaries. This experience awakens a genuine love in Cliff, leading him to choose a quiet and peaceful life with Charlie.

This decision puts him at odds with his sister Michelle, who scolds him for being a coward and weeps in frustration when he refuses to follow her own more ambitious and ruthless path. While Michelle continues to pursue power and eventually joins the Guardians only to be betrayed, Cliff seeks stability away from the chaos. Demonstrating his medical capabilities, Cliff is shown to be competent in his field, reluctantly agreeing to use the sickbays equipment to surgically remove needles from a wound, showcasing the practical skills of his nursing specialty. Cliff is also known to speak with a threatening, rough-edged tone when confronting those who have betrayed him, revealing a core of inner strength and ferocity beneath his beautiful exterior.
