Rikka Takanashi is the main heroine of Chuunibyou demo Koi ga Shitai, the Kyoto Animation series that first aired in 2012 about students with delusional fantasy personas. Rikka believes her right eye is the Jaou Shingan, a cursed power she keeps under an eyepatch, and she invents German-named techniques like the Schwarz Shield in battle monologues. Fans cut these short declarations into soundboards alongside other anime power calls such as the Mangekyo Sharingan, using them for edits, streams, and playful roleplay online.
