Summary
Ruka Urushibara is a sixteen-year-old second-year student at Kasensou Private Preparatory Academy and a classmate of Mayuri. Born biologically male, he possesses the demeanor of a polite, well-mannered, and refined young woman. Rintarou is the only person he addresses with specific honorifics. Though he rarely forces his views on others, he becomes noticeably bashful and blushes frequently when he does. Serious by nature, Ruka is gullible and tends to accept others' words at face value, leading him to believe the absurd claims Rintarou makes are real facts. He is extremely shy and often declines Mayuri’s requests for him to participate in cosplay.
