Key Character Umi Katō Takes Center Stage in Latest Summer Pockets Anime Visual and Trailer

The highly anticipated anime adaptation of Summer Pockets, brought to life by Studio Feel, has captivated audiences since its April 2025 premiere. We are thrilled to report the unveiling of a breathtaking new promotional visual and an enthralling trailer. This latest release shines a direct spotlight on the pivotal story arc of Umi Katō, a character whose journey is central to the series' emotional core.

Fans are treated to a deeper glimpse into Umi's profound struggles, brought to life by the talented voice actress Aimi Tanaka. Her character grapples with unique powers and a deeply complex relationship with her mother, Shiroha Naruse. The newly released seventh promotional video masterfully previews the opening theme song, "Finistella," an evocative track performed by the renowned Konomi Suzuki, setting the perfect tone for the poignant narrative to unfold.

Umi’s storyline is particularly compelling, as it delves into her desperate attempts to prevent her mother from acquiring supernatural abilities. This quest leads her on an extraordinary path, rewinding time back to Shiroha's childhood. This narrative device intricately weaves together themes of profound nostalgia, unbreakable maternal bonds, and the enigmatic complexities of time loops. The arc promises high emotional stakes, particularly as it explores Umi’s poignant deterioration as her spiritual powers wane, underscoring the intrinsic supernatural elements that define the series.

Summer Pockets originally debuted as a critically acclaimed visual novel for PC in 2018, developed by Visual Arts/Key. It has since expanded its reach with updated versions available on platforms such as Nintendo Switch and PlayStation 4. The television anime faithfully translates the rich emotional depth and picturesque island setting of its source material, meticulously capturing the essence of a nostalgic summer brimming with mysterious girls and ancient folklore, all set against the backdrop of the isolated Torishirojima island.

As the anime continues to build momentum, a compilation film has been officially announced, slated for release in Japan on August 15, 2025, promising further exploration of this captivating universe. For a global audience, Crunchyroll ensures accessibility by streaming the series concurrently with its Japanese broadcasts, allowing fans worldwide to join the unfolding narrative. The recent visual and trailer unequivocally highlight Umi’s indispensable role, generating immense anticipation for the culmination of her story within this unfolding anime saga.
