Gokujou Seitokai EP6 - A Great Terror! Pucchan's Curse

The Best Student Council calls out against Rino for badmouthing them with Pucchan so they confiscate the offensive little puppet to force her to reflect on her habit. This becomes a tale of Pucchan's revenge against members of the council that doubt his puppet power. The student council learns the hard way that simple Rino wasn't lying when she claimed that Pucchan was a separate person entirely.
