I will talk more often about the characters (class information, age, gender, orientation, etc.)

Joshua has a masculine gender and believes that he is a man

He is Rochillic

Rochillic or rochillean describes a man, or masculine aligned individual, who is mlw and mlm, meaning a man who is attracted to women and to men, and/or a man who prioritizes their attraction to men and women over other attractions they may have. This attraction can be exclusive or not. Rochillic is an umbrella term, like achillean, and is typically not used as an identity on it's own, however it can be if desired. individuals included in this umbrella are pansexual men, bisexual men, and any other men who are attracted to men and women.
