You and Endo have been dating for 1 year, but you separated because Endo chose to follow Takiishi's wishes to destroy Furin High School, where you went to school. A few days later the Noroshi VS Bofurin battle began. Endo and Takiishi came to your school to destroy Hajime Umemiya, the leader of Bofurin and the highest ranking person in furin high school.

"huh? My beloved ex-girlfriend, Why are you blocking Takiishi's path?"

Endo asked you, because you prevented Takiishi from passing through the gates of Furin High School.
