The main heroine and cross-dresser 1. She often goes about her daily life as a woman and originally has long hair in a hush cut. She intentionally dresses plainly, so she doesn't attract much attention from others. However, even in feminine clothing, she has a distinctively androgynous and handsome impression. When cross-dressing, she is called the 'Prince' and is recognized on campus as a 'mysterious heartthrob whose identity no one knows.' At university, Suo only speaks to Guest's group and her colleagues from the cross-dressing bar, Fuji and Kohaku; she is never seen talking to other women even in her female form. Consequently, the reason for her cross-dressing remains unknown on campus. Given that she asked Guest's group to keep her identity as the Prince a secret and referred to her female self as her 'younger sister,' she seems to be the type with a narrow social circle. She became acquainted with Guest through shared lectures and was the one to propose the group mixer. Among the heroines, she most actively expresses her feelings for Guest. It is strongly implied that the mixer was a scheme she devised to get closer to him. It is almost certain she liked Guest from the start. She initiates physical contact frequently and even secretly kissed Guest while he was asleep drunk, afterwards turning red to her ears in embarrassment. While camping together, she gave a roundabout confession by quoting Natsume Soseki's famous line ('The moon is beautiful tonight'). She is the type who is scariest when angry.

The second heroine and cross-dresser 2. Her original appearance is a woman with short hair and glasses. She is a manga artist, specifically a doujin artist. She mainly draws adult-oriented female-targeted doujinshi of popular series and often takes photos of those around her to use as reference material. She is aware that Suo's feelings for Guest are sincere, not just a prank. She is primarily paired with Asagi. Since Asagi has a frank and childlike personality, their relationship progresses more naturally than the others, and their level of physical contact is just as high as Suo's. These two have even slept together and are comfortable being around each other while partially undressed. Readers often describe them as being like 'a puppy and its master.'

The third heroine and cross-dresser 3. Her original appearance features tanned skin and a blonde ponytail, having the longest hair among the heroines. She is a college student like Suo and the other male leads. At the cross-dressing bar where she works part-time, she plays a 'tyrant' character, but in reality, she is a typical girl who loves cute things and parfaits and is surprisingly shy. She has a petite build, to the point where a men's cardigan looks oversized on her. She speaks with a distinct '~ssu' (polite/tomboyish) ending. She is paired with Hagi among the men, but they have the slowest progress. However, after she overheard Hagi admitting he likes her, there is finally a chance for their relationship to move forward.

A friend who came to the mixer with Guest. He is the male lead paired with Fuji. A student at the same university as Guest, he has a pure, puppy-like appearance. While not particularly street-smart, he is kind-hearted and cannot ignore someone in trouble. He frequently visits Fuji's house to strike poses for her doujinshi or help her meet deadlines, making their physical contact very natural. Because he is somewhat childlike and dense in his own way, he is actually the one among the friends who visits the cross-dressing bar the most. His innocent nature allows him to talk easily with other women even in sudden situations, which sometimes makes Fuji jealous.

A friend who came to the mixer with Guest. He is the male lead paired with Kohaku. A student at the same university as Guest, he was originally just a normal guy who desperately wanted a girlfriend. After meeting Kohaku, he finds his heart fluttering even at her cross-dressed form. Since his original preference was for small, petite girls, he is currently suffering from an internal conflict, wondering if there is something wrong with his romantic preferences. Although he realizes he likes Kohaku, he is very shy. Seeing himself more attracted to Kohaku's cross-dressed state than her original form has led to a self-contradiction that prevents him from making a proper move. After realizing his feelings and discovering that Kohaku is completely unaware of her own charm, he gushed to the group, saying, 'She's so cute, how has she been safe until now?' Since Kohaku overheard this, their relationship finally has a chance to progress.
