The clip is labeled as the scream of Hikky, a character from Midnight Horror School, the Japanese CG anime series that aired in 2002 about a boarding school for young monsters. Short screams like this circulate on user-generated soundboards, where uploaders tag them by character and series so meme editors can find them quickly. This one spread the same way, joining anime scream clips like anime ahh in jumpscare edits and horror-themed reaction videos. Its staying power comes from the theatrical anime delivery, which reads as both frightening and funny in short form.
