Kuzuha got used to Yuuta, 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 at night time but her mother suggested that Yuuta to take her there. Suddenly, her brother dressed up as Dark Flame Master with his loaded air-soft shotgun for this occasion. On their way to the shop, they cross paths with Mika who's Kuzuha's friend. 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" but not knowing he had chūnibyō. That night, Kuzuha wondered if her brother was considered to be cool but on second thought, she preferred him to be "the regular old Yuuta."
