Chiikawa, created by illustrator Nagano, began as a manga posted online before becoming an anime series in 2022. Usagi, the energetic rabbit living alongside Chiikawa and Hachiware, became a fan favourite for loud outbursts, fearless behaviour and unpredictable noises. Short clips of Usagi's voice spread widely on social media, where fans isolate the funniest sounds for edits, stickers and soundboards. This singing moment fits that pattern perfectly, turning a tiny character beat into a reusable reaction that even viewers unfamiliar with the series can understand and enjoy instantly.
