Ellen Baker is a character from the 2016 edition of 'New Horizon,' a popular English language textbook used in Japanese junior high schools. Designed by illustrator Denchu-bo, the character went viral almost instantly on social media due to her expressive anime aesthetic, which was a significant departure from previous textbook designs. The most famous image features her in a batting stance, which became a versatile template for expressing enthusiasm, unexpected aggression, or simply 'swinging' into action. While initially intended for education, the internet quickly turned her into a beloved figure and a symbol of wholesome yet energetic teaching, solidifying her place in anime meme history.
