Kuzuha Togashi is Yuuta Togashi's younger sister. She knows Yuuta very well, especially how he acted while he still had Chūnibyō in middle school as the Dark Flame Master, though she always considered his behavior embarrassing.
Kuzuha had gotten used to her older brother's delusions since she was young. In Chuunibyou demo Koi ga Shitai Lite Episode 3, Kuzuha decided to go the stationery shop one night, but her mother suggested that Yuuta take her there. Suddenly, her brother dressed up as the Dark Flame Master with his loaded air-soft shotgun for this occasion. On their way to the shop, they cross paths with Mika, a friend of Kuzuha. Kuzuha tried to distract Mika from noticing her brother's presence because it would be embarrassing for her if her friend knew about her brother's chūnibyō. In the end, Mika found out about Yuuta's presence and stated that he was "cool", although she did not know that he had chūnibyō. That night, Kuzuha wondered if her brother was really "cool", but on second thought, she preferred the regular old Yuuta.
Kuzuha has short, neck length, black hair and green eyes.
Kuzuha is a responsible individual and is often seen helping with household chores.
