Season 1

Thanks to the mysterious penfriend Mr. Poppit Rino Rando is attending Miyagami School, accompanied by her sarcastic puppet Pucchan. She finds out the apartment organised for her has burnt down, so she heads up to the school. She ends up sleeping outside after she gets frightened by a bear in the bushes and another student, Kaori Izumi, who turns out to be her class president. Rino ends up trying for a position on the Student Council so she can get somewhere to live (they're given an apartment building to live in), and by a series of accidents on the way to the Student Council building manages to defeat the arsonist who burnt down her apartment, thus ending up on the best student council!

The council throws a welcoming party for Rino (What about the budget?!) as the school is jealous over Rino being put on the Best Student Council on her first day.

Rino is on the Best Student Council, which comes as a shock to nearly the whole school and many of the students can't understand why Rino made it onto the Best Student Council. She's not the brightest, failing her tests miserably, or good at sports. Not to mention the fact that she's clumsy. So what does she bring to the group? Why did the President of the Best Student Council pick her? Because of this, rumors start to fly about Rino and the President. Those opposed to the President's decision are upset and in disbelief. The Paparazzi Club, the Photography Club, and the Newspaper Club all team up to find out just what's going on.

The puppet theater is sabotaged; Rino and Pucchan investigate.

The budget is overextended and a culinary battle between the Assault and Covert squad is staged to decide who gets the next month's financing.

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.

Mayura Ichikawa, the best student council's treasurer who is usually stressing out about the school budget, requests a day off. Mayura is spotted sneaking off campus, all gussied up. The best student council wasn't going to get involved until it is discovered that Mayura is going on a date, and the couple was spotted heading towards the red light district.

Exams are coming up and it just wouldn't be acceptable for any best student council member to fail. Reno, Rein, and Cyndi are one step away from failing so they'll all have study night and day with the help of the other best student council members to pass. Will they be able to pass their exams?

Sayuri is attacked by a mysterious girl who also practices the way of the sword. Who is she? And what does she have against Sayuri?

The girls start to wonder why President Kanade is always gone on the third Sunday of each month. Kuon decides to have the Covert Squad find out what the President is up to. Nanaho reflects upon the day she first met Kanade.

Kanade and Nanaho return to the best student council dorms to find them virtually destroyed. Rino tells them the destruction of the dorms is a short story which begins when Rino met a girl named Minamo.

The best student council decides to put on a play, titled "The Alien Space Creature from Outer Space" written by Minamo, to raise money. Will their play be a financial success?
