The sound comes from fan edits of Yotsuba&!, the slice of life manga by Kiyohiko Azuma that began in 2003, following energetic five year old Yotsuba Koiwai and her father Yousuke. Because the series has no official anime adaptation, short voiced clips like this spread through fan dubs, edits and soundboards rather than a TV episode. Fans share the Super Papa line for its mix of innocence and admiration, and it keeps circulating in wholesome anime communities as a quick way to celebrate dads and everyday heroes.
About this sound
Yotsuba saying Super Papa in a cute, excited voice from Yotsuba&! Creators use it for sweet, funny family moments and wholesome anime edits online.
This is a short voice clip of Yotsuba Koiwai cheerfully calling out to her adoptive father as Super Papa, delivered in her bright, high pitched and completely earnest child voice. The line lasts only a few seconds but carries all of her admiration and excitement in one burst, which is why it lands as instantly wholesome rather than just cute. Viewers hear pure hero worship from a five year old who genuinely believes her dad can do anything, and that sincerity makes the moment funny, warm and very easy to reuse out of context.
