@daime17 : Awesome! Thanks! I've got a strange fascination with characters that have
that face... Despite my asking around, nobody seemed to be able to put a name to it (only that it is regarded as a subtype of kuudere), but it IS a recurring thing... which I only cottoned on to after seeing Renge in
Non Non Biyori...
Ritos from
Shukufuku no Campanella and Nao from
Koi Neko also qualify... but I still kinda think of it as Renge-Face.
Oh... and Tetra from
Isekai Kenkokuki does it sometimes, but it isn't a full-time thing.
