Azuma chizuru (and a man) is probably spanked in "Haiku oukoku ga yuku"(lit. a haiku kingdom is going),episode 8 aired on NHK.
In this episode,they visit saka cho,Hiroshima and in this town there is the demon who spanks child and they two are spanked by this demon and made haiku there.
If we go to NHK site,we can watch free sample movie,

but only a man is spanked...
According to what an official site (in Japanese) says,chizuru also is spanked( and this spanking means to drive evil spirits out,not to punish someone).
