“Watashi, kininarimasu” is strongly associated with Eru Chitanda from the 2012 anime Hyouka, where the phrase became one of her signature lines. Fans spread it through anime clips, subtitles and reaction edits because it neatly captures intense curiosity in just a few words. It remains popular in meme culture and short video editing because the delivery is recognizable even to many casual anime viewers. It often appears alongside other anime reaction audio such as Tuturu in fandom-heavy edits.
