Kaede Azusagawa is one of the main characters of the Seishun Buta Yarou wa Bunny Girl Senpai no Yume wo Minai series. She is the younger sister of Sakuta Azusagawa who suffered amnesia and gained a different personality after her ordeal with Adolescence Syndrome stemming from online bullying. Since then, she has lived with Sakuta and has not attended school.
Pre-amnesia: Kaede originally had a kind, yet cheeky personality which granted her little difficulty with social interaction. She regains this personality after completing her list of goals.
Post-amnesia: Ever since Kaede lost her memories and gained a new personality as a result of Adolescence Syndrome, she shut herself away from the internet and the outside world in general and developed a phobia of strangers, as shown when first meeting Mai Sakurajima. Kaede tended to refer to herself in the third person.
Sometime during Kaede's time in middle school, she was a victim of online bullying and death threats. As a result of Adolescence Syndrome, this caused her to suffer various physical injuries and she was only able to recover after she stopped using social media and going to school.
Unfortunately, she had also developed amnesia as a way to separate herself from her experience with being harassed, which drove her mother and father to abandon her with Sakuta Azusagawa.
After her brother received advice from Shoko Makinohara, she was gifted a pen and notebook and she was suggested to write her first name in hiragana (かえで) instead of kanji (花楓). Kaede was declared the current "Kaede" and her former self was dubbed "Kaede-san" by Sakuta, which earned her tearful approval.
Since then, she lived and behaved differently before her ordeal with Adolescence Syndrome. As a result, she developed a phobia with strangers and spent most of her time at home.
