Arima Kana is a former child star and central character in Oshi no Ko, the manga by Aka Akasaka and Mengo Yokoyari that began in 2020 and was adapted into an anime in 2023, where she is voiced in Japanese by Megumi Han. Short clips of her losing her temper circulate on soundboards and in fan edits because her expressive, easily flustered personality makes even a single shouted line instantly recognisable to fans. This scream has become a quick shorthand for fed-up anime reactions online.
