Summer Pockets is set on an isolated, rural, and peaceful island on the Seto Inland Sea called Torishirojima, which has a population of about 2,000 people. The protagonist, Hairi Takahara, grew up in an urban setting, but after an unpleasant incident, he uses the recent death of his grandmother as an excuse to come to the island to take care of her estate sale. Once there, he gets to know four girls, who are the focus of the story: Shiroha Naruse, who forgot her summer vacation; Ao Sorakado, who is pursuing the legends of the island; Kamome Kushima, a high-class girl looking for a pirate ship; and Tsumugi Wenders, a younger girl trying to find herself.

After a harrowing period of war, the countries of Valcania, Dulkheim and Igrecias form a confederation and begin a new system of political order. However, three years later many are still unhappy with this system, and a group of nobles led by Lyros, Prince of Valcania, plan a coup d'etat. Two days before the planned coup, Lyros asks Dianna Silvernale, the captain of the Royal Guard of Valcania, to join him in order to overthrow the confederation and reclaim the nation for the sake of Valcania's people. Now, Lady Silvernale has very little time to decide whether to follow her prince or to prevent another war that will likely break out.
