Ranmaru Fujieda is a supporting character in Haikara-san ga Tōru who occupies a unique place in the life of the heroine, Benio Hanamura. He is the son of the family living next door to the Hanamura household, making him Benio’s childhood neighbor and friend, and he is one year younger than she is. His family is connected to business and commerce, a background that becomes important later in his story.

Ranmaru works as a kabuki actor specializing in onnagata, the performance of female roles. His delicate good looks and naturally feminine bearing make him well suited to these parts, and his appearance is striking enough that he is described as a beautiful young man who embodies an early version of the feminine male character type later known in Japanese popular culture as otokonoko. In spite of his gentle, feminine manner, his romantic feelings are directed toward women. He has harbored a crush on Benio ever since childhood, and this affection is the strongest force behind his actions throughout the story. His beauty also means that men are frequently drawn to him, a recurring detail that plays on the contrast between how others perceive him and his own nature.

Ranmaru’s most memorable role in the narrative comes from his devotion to Benio. When circumstances place Benio in the household of the Ijuin family, where she is being trained as a prospective bride, Ranmaru makes use of his stage skills to disguise himself as a young woman named Ranko. In this disguise he enters the Ijuin home as a maid assigned to serve Benio, allowing him to stay close to her and look after her from within. The deception shows both his talent for female impersonation and the lengths he is willing to go for the girl he loves. His feelings eventually surface openly; after learning that Benio is engaged to Shinobu Ijuin, he confesses his love to her, even though the attachment is not returned in the same way.

Despite the unrequited nature of his feelings, Ranmaru remains a loyal presence in Benio’s life and an important personal connection from her childhood. His friendship with Benio is one of the steady relationships in the story, and he is often portrayed in situations that highlight his gentleness, his emotional sensitivity, and his willingness to put Benio’s welfare ahead of his own comfort.

Ranmaru also undergoes meaningful development over the course of the story. His early life is defined by his devotion to kabuki and his pursuit of an existence shaped around his closeness to Benio, even when that closeness requires hiding his true identity. Later events push him toward a more settled and honest path. Following the death of Shinobu, Benio tells Ranmaru to return to his family home, and he ultimately does so, giving up his wandering connection to the theatrical world and taking up the family business instead. This turn marks his growth from a lovesick young actor willing to disguise himself for the sake of his childhood sweetheart into someone who accepts responsibility and moves forward with his own life.

In terms of abilities, Ranmaru’s defining skill is his artistry as an onnagata performer. His ability to move, speak, and present himself convincingly as a woman is highly developed, and it functions as more than a stage talent because it allows him to sustain the Ranko disguise in everyday interactions without being detected. His profession also gives him a performer’s awareness of appearance and presentation, which blends naturally with his graceful and refined demeanor.

Altogether, Ranmaru Fujieda is best understood as a loyal and emotionally sincere young man whose feminine appearance and professional specialty mask a straightforward romantic heart. His love for Benio, his memorable decision to infiltrate the Ijuin household as a maid, and his eventual choice to return to his family and its business together form a complete arc of devotion, self-sacrifice, and personal growth.
