Neferpitou is one of the Royal Guards in Hunter x Hunter, a Chimera Ant known for a calm, catlike demeanour and unsettling power. Nyaruhodo is a common Japanese expression meaning I see, often used when someone grasps an explanation. Fans have clipped this brief utterance for use as a reaction sound, because its deadpan delivery fits moments of sudden understanding in edits and memes. Its brevity makes it easy to drop into short videos, and its link to a memorable antagonist keeps it recognisable among anime audiences.
