Rikka's case of chuunibyou is common among chuunibyou cases, constantly living out her fantasies and exhibiting strange behaviors as a result. She is very dramatic and theatrical, claiming to possess the "Tyrant's Eye" which allows her to reveal destinies, even wearing an eye-patch to "seal its' powers". Her delusions tend to reflect her feelings in real life, such as how she professed that tomatoes burn away one’s mana so as to avoid eating.
