Japanese donut bakery chain, “Mister Donut”, has apparently been brainwashed by the creeping cuteness from Haiyore! Nyaruko, Nyaruko, as the receipts have been infected with strings of “nya” and “uuu” sounds.
This doughnuts shop, popularly recognized as “Mista Donutsu” thanks to Nisemonogatari, has jumped onto the Haiyore! Nyaruko opening sequence bandwagon – an OP which has been ensnaring many through its moe sounds, and equally as cute sights. The receipts now come printed with “nya” on them, followed by a Nyaruko signature pose, “nya”, and a pose once more – all speckled with some “uuu” in between.
The Nyaruko phenyamennyan can be experienced below at one’s own risk:
