Summer Pockets is a romance adventure game released by Key in June 2018.
Set on the fictional Torishirojima Island in the Seto Inland Sea,
the story follows Hairi Takahara, who visits the island for his late grandmother’s belongings and experiences a refreshing, emotional summer with new friends.
The game became beloved for its charming characters and nostalgic summertime atmosphere,
spawning enhanced versions, manga adaptations, radio shows, and a TV anime airing from 2025.
After the release of Harmonia in 2016, Key sought a new project distinct from previous works like Angel Beats!.
The concept came from Jun Maeda, with the intention to keep the classic "enjoyable daily life and moving story" flavor, but with a fresh take.
Instead of following existing Key works too closely, a company-wide pitch resulted in Maeda’s "summer memories on a remote island" theme taking the spotlight.
Due to Maeda’s health at the time, scenario writers Yu Niijima and Hasama joined, bringing new perspectives while respecting Maeda’s narrative framework.
Torishirojima, inspired by real Seto Inland Sea islands such as Naoshima, Ogijima, and Megijima, is a remote, serene island.
The setting oozes nostalgia with its rural landscapes, picturesque beaches, and strong sense of community.
Myths about spirits, old traditions, and emotional connections between the locals form a core part of the island’s mood.
From the dock to the onsen, to mysterious forests and lighthouses, every location is infused with a gentle yet mysterious warmth.
During summer break, Hairi Takahara visits Torishirojima to help his aunt Kyoko Misaki organize his late grandmother’s belongings.
While living on the island, Hairi befriends quirky locals and a series of mysterious, colorful heroines—Shiroha Naruse, Ao Sorakado, Kamome Kushima, and Tsumugi Wenders.
Each girl hides a secret closely tied to the island’s lore.
By following each path, Hairi unravels individual stories of self-discovery, loss, and hope.
Clearing all four heroines’ stories unlocks the special ALKA and Pocket endings, revealing deeper truths about Torishirojima and the protagonist’s journey.
The Reflection Blue enhanced version introduces more routes and heroines, each adding new layers to the bittersweet narrative of summer’s fleeting beauty.
- ALKA Route: The pivotal "grand route" that reveals the central mystery after all heroine stories are cleared.
- Pocket Route: A post-ending route unlocking after ALKA, offering emotional closure and tying together the broader themes.
- Seven Shadow Butterflies: Spirit-like beings holding echoes of memories, crucial to certain character arcs.
- Grand Ending: The ultimate resolution, often involving supernatural elements and closure for the cast.
