A year has passed since Tohru Honda began living in the Souma residence, and she has since created stronger relationships with its inhabitants Shigure, Kyou, and Yuki. She has also grown closer to the rest of the Souma family and has become familiar with their ancestral secret, having helped them with many of their personal issues. The closer Tohru gets, however, the more she begins to realize that their secret holds a darker truth than she first presumed.

Summer is approaching and Tohru is invited to spend her days with the Soumas, mainly Kyou and Yuki. Tohru wishes for an easy-going vacation, but her close relationships with the two boys and the rest of the Soumas may prove to cause trouble. As they grow more intimate, their carefree time together is hindered by older hardships and feelings from the past that begin to resurface. The Eternal Banquet also dawns on the members of the zodiac, and they must tend to their duties alongside the unnerving head of the family, Akito Souma.

With the banquet approaching and a plethora of feelings to be solved, will Tohru's life with the Soumas remain peaceful, or will she find herself in a situation from which she cannot escape?
