Shota Aizawa is a central character in My Hero Academia, the manga series created by Kohei Horikoshi in 2014 and adapted into an anime in 2016. As Eraser Head and homeroom teacher of Class 1-A at U.A. High School, he is known for his logical, no-nonsense attitude and exhausted tone. Short clips of his lines circulate widely in anime fan edits and reaction posts, where this i don't care moment is used as a shorthand for complete indifference, similar in spirit to other blunt anime reaction sounds.
