Hah, just watched it and, yeah... It's good so far except yeah, the ending song and Paruru's acting.
I lol'd when I see Rie, seriously, she always appear in Paruru's drama
Nobunaga? Hm... Acchan? Yui? Jurina? Mayu maybe? Since she'll defeat the teppen (well, maybe. That's what I understand with my poor Nihongo) those 4 would be a good idea. Maybe.
Well, i guess I'll wait for the eng sub, watching it all over again and wait for the next episode and so on.
Ponkotsu Blues, I think that it's a good song. IMO
