"Reality be rent... Synapse break.... Banishment this world!!"

From wiki:
Rikka Takanashi is a chunibyo practitioner who enrolls in Icho Private High School, the same school as Yuuta Togashi. Unlike Yuuta, she still suffers from chunibyo (eighth-grader syndrome). She believes she is a sorceress possessed by the "Tyrant's Eye" ("Eye of the Wicked Lord" in the English dub) that will reveal destinies. She wears a medical eyepatch over her right eye to seal her "Tyrant's Eye". Those who have seen her "Tyrant's Eye" are considered as completely signing a contract with her. She moved into the apartment above Yuuta's apartment to stay with her sister,

Happy Chinese New Year!
