The subject of today's happiness training is "Good Luck Orienteering!" Lead by the assistant Timothy, Hanako and her friends arrive at a mountain near school. While experiencing typical levels of misfortune, the girls have a picnic, and Hibari realizes the true meaning of the happiness training.

Hanako gets a fever and leaves class early. Hibari and Botan go to visit her at home with gifts and the day's homework. When Hanako misses school the next day, the four girls of class 7 begin creating something that makes wishes come true...

Summer vacation has finally begun. Botan records the fun days she is having with her friends from class 7 in her journal. Going to karaoke on the way home from school, swimming at the beach by the Kumegawa villa... As they describe their summers filled with "happiness," she smiles.
