Rino Rando is is a klutzy orphan with a benefactor she knows only by correspondence, and a puppet named Pucchan that has such a distinct personality that everyone including Rino treats it as a true person. She is granted a transfer to the prestigious private girls school the Miyagami Academy that is ruled not by the faculty, but by the Best Student Council. Once there she is befriended by the Council's president, Kanade Jinguji, and inducted into the Best Student Council through no virtue of her own. The council has many challenges, and often Rino complicates things with her blundering.
