Yuno and her friends go to the zoo for a school assignment to sketch some of the animals. Yoshinoya dresses up like a tour guide and acts like one on the way to the zoo by pointing things outside the window to the students, but soon becomes very carsick and has to stop. At the zoo, Yuno and her friends go around and see many of the animals. Later, Yoshinoya ends up in front of the Hidamari Apartments, and Yuno and her friends take her to Hiro's apartment when she rests for a time. After she leaves, they discuss some of the rumors they have heard about Yoshinoya.

Yuno and Miyako attend the school entrance ceremony, in which Miyako falls asleep due to principal's tedious speech. Meanwhile, Hiro and Sae stay at the Hidamari apartment and they happen to meet with Misato and the landlady in the morning. After the ceremony, Hiro and Sae makes a surprise welcome party for the new Hidamari neighbors.

In the early morning, Yuno makes onigiri bentos for Miyako and herself. When it is a lunch time, Yuno goes up to the rooftop of Yamabuki high school, which is prohibited area for students. After a brief assault of hungry pigeons, Yuno falls asleep on the rooftop. After the PE class in the afternoon, Yuno and her friends finds out that Hiro has been missing. When Yuno goes back to the dressing room to pick up the jerseys that she left, she hears a strange noise behind a door, where an unconscious Hiro is found. Then Yuno and her friends come to the conclusion that Hiro had stopped eating to fit into a tight pair of pants, where in actuality, Hiro had bumped her head on the low ceiling while putting them on.

May 9th: Hiro and Sae decide to clean their curtains using Miyako's pool. May 25th: The Landlady treats the girls to an all you can eat Barbeque.

New Years Eve is here and this time all the girls will be spending it at Hidamari Apartments. Whilst Sae and Hiro are at a study session, the rest of the girls clean up and prepare for festivities later. Later, after the bells chime in the New Year, the girls all visit the shrine, where they meet other friends and acquaintances. After watching the sunrise together, the girls then return home to sleep and contemplate the coming year.
