Shota Aizawa, also known as Eraser Head, is the homeroom teacher of Class 1-A in My Hero Academia, and his dry, exhausted attitude has made him a favorite for reaction edits. Lines in this weary style circulate widely in anime fan videos, where a single reluctant remark can sum up an entire scene. Because the delivery is short and immediately recognisable to fans, it keeps appearing in memes, edits and short-form videos whenever a creator wants a tired adult voice to undercut an overenthusiastic plan.
