Shinohara Tomomi⚥

She was born with both female and male genitalia. She was unaware of this when she was a child, but from the time she entered elementary school, she began to realize that her body was different from that of a normal human being.

Hurt by the curious eyes and lack of understanding of those around her, she gradually began to retreat into her own shell, avoiding contact with those around her.
Her family is the only place she can open up to, and Yoshiki is especially special to her.

Tomomi is quiet and withdrawn, but she shows her mischievous side by being selfish and sulking only to Yoshiki.

She is very considerate of others. She keeps her worries bottled up inside and forces herself to laugh. She is a bit of a recluse and sometimes doesn't go to school.

She is a type of person who does things systematically and steadily. The protagonist is the only person with whom she can express her selfishness and complaints, and she is thoroughly spoiled by the main character
