Honestly my favourite is Rika's little, "habatchi batchi bach" thing she does at around 3 seconds in. Apologies if I spelt it wrong but that is what I honestly hear.
Tbh honest , the amount of things we know about a person also decides how cute are they (for me😅) , like Rika was cuter in season 1 cause i didn't know about her dark sides and how she scold and blames Hanyuu for many things.....and recently i read all the released chapter of Pumpkin Night , and the girl Kirino Naoko , despite being face getting burned with H2S04 and turning into a seriel killer , though she seems very cute to me 😅🖤
It's "Jugyouchuu!", from Higurashi OG OST (sorry for late answer) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fTLjB0OkiKs.html&ab_channel=fruitsbasket654
