The phrase comes from the Danganronpa visual novel series, where sore wa chigau yo is used during class trials to refute a contradiction in someone's testimony. Nagito Komaeda, a central character in Danganronpa 2: Goodbye Despair from 2012, became closely linked to the line through fan edits and voice clips shared online. Its clear, confrontational delivery helped it spread beyond the games into anime fandom, where fans use tuturu and other anime reaction sounds alongside it, but this clip remains popular because it instantly signals a confident correction without needing context.
