Yūjirō Shiratori is a high school student who cross-dresses in women's clothing and identifies as homosexual, featuring blonde hair with bangs hanging on the right side and light blue eyes. He serves as president of the school's Cooking Club.

Shiratori displays a self-centered personality, consistently believing himself the most important person in any situation. Despite his traditionally feminine presentation, he possesses physical strength comparable to a delinquent, contributing to his distinctive presence.

He maintains a notable dynamic with classmate Akira Ueda, who acts as his devoted servant. Ueda meticulously follows Shiratori's orders due to deep admiration, though the narrative clarifies Ueda is not gay—establishing a relationship parodying BL-themed fan service tropes. Shiratori accepts this devotion without romantic reciprocation.

His interactions with protagonist Ryo Sakaguchi are limited, occurring through shared acquaintances like Ueda or during club activities. Sakaguchi occasionally observes Shiratori in contexts sparking BL-inspired fantasies, influenced by his appearance and mannerisms. Classmate Toshiaki Nakamura uses the affectionate nickname "Toricchi" for him.

No significant character development or expanded background beyond these core traits and relationships appears across the anime's 12 episodes or related media.
