Description
Kaguya Arikawa is a first-year high school student and the younger brother of Hime Arikawa. Unlike his brother, who is forced into the role, Kaguya willingly chooses to cross-dress because he enjoys the attention and admiration it brings him. He has a petite build, standing 152 cm tall and weighing 39 kg, with shoulder-length pink hair and blue eyes, often styled in twintails.

Kaguya possesses a narcissistic personality, being very confident in his own cuteness and appearance. He has a devoted following of admirers at school whom he refers to as his "servants". He is also a pronounced brocon, holding a deep and possessive love for his older brother, Hime. Kaguya is fiercely protective of Hime, viewing him as the only consistent parental figure in his life since their parents are neglectful and often absent. This protectiveness fuels his primary motivation in the story: to rescue his brother after Hime is effectively kidnapped by the student council to pay off a family debt. To achieve this, Kaguya joins the Disciplinary Committee to oppose the student council and get his brother back.

Kaguya's past has significantly shaped his personality. During his childhood, he was frequently bullied by classmates for his cross-dressing, which caused him to become withdrawn and angry. His circumstances were worsened by his parents' neglect, which forced him and Hime to move often. A pivotal moment in his development was meeting his friend No. 1. After learning that Kaguya was being ostracized, No. 1 chose to cross-dress as well, sharing the burden of the bullying and becoming Kaguya's closest friend. This event helped him open up, though his core devotion to Hime remains his strongest character trait. Kaguya refers to the apartment he shares with his brother as "our love nest" and has been known to show his affection in highly possessive, and at times inappropriate, ways.

In the spin-off series Himegoto+, Kaguya takes on the role of the main protagonist. While the student council supports the brothers' living expenses, Kaguya often wastes his share on luxury items like bags and cosmetics, forcing Hime to work additional part-time jobs to make ends meet. His birthday is on September 10.
