Сестры Минами OVA-2

Halloween descends upon the Minami family: Kana surprises Makoto wearing a vampire costume that Touma made. Since Makoto knows nothing about Halloween, Kana enlightens him. To get into the spirit Makoto is dressed up as a magical girl, and saying "Trick of Treat" to Takeru, yields some candy. The New Year's Day festivities are pretty much over on January 3rd, but when Hayami hands out sweet half-sake (without alcohol supposedly) Yuka and the other girls all end up slightly tipsy. Preparing food on a whim does not agree with Chiaki, she prefers time and effort put into its preparation. Kana and Haruka then start doing things in a whim... with mixed results. On a hot day the air conditioner breaks down, so Kana and the other girls decide not to go to the pool, that would take effort, so they sit around the table in their swimsuits.
