Last Gender: Nanimono demo Nai Watashitachi

Welcome to BAR California, a place for you to reveal your true self. People of different genders, propensities, and sexual orientations gather at a certain chic bar that's hidden from the public eye. While some come in search of themselves, others step into the establishment looking for sex and love. There are as many sexualities as there are people, and the patrons' stories intertwine as they struggle to find happiness. A bisexual trans woman who's been hurt by the voices of others wishes she had a "normal" relationship; a married, middle-aged salaryman secretly expresses his female side; and a pansexual cis guy is on the lookout for true love.
