Aizawa Shota, also known as Eraser Head, is the homeroom teacher of Class 1-A in My Hero Academia, the manga series that began in 2014 and anime adaptation from 2016. He is known for his exhausted personality, blunt honesty and lack of interest in wasting energy. Short voice clips of his dismissive lines circulate widely among anime fans, and this go away moment became popular as a reusable reaction for edits, streams and chats where a dry, unimpressed response fits better than an angry one.
