Ranma was not only a killer comedy for me to read in between classes, it became an obsession that was focused on my biggest problem with the series. Why did Ranma ever want to go back to being a boy?
Most popular yuri series taking place at a school have a unique thing that sets them apart from the pack. Canno’s Cider and Crybaby has the focus on the girls in a paranormal club. Shinozaki-san Ki wo Ota Shika ni! by Saku Saku Tei has the story be a comedy about a girl becoming more of a nerd as she falls deeper into love. Hayashiya Shizuru’s A Lifeform in Puberty — Vega has one of the main girls as an alien that gets super powers from kissing and affection. People get creative with their hooks.
Citrus’ hook is that the main characters are step-sisters.
