Summer Pockets

Summer Pockets is a romance visual novel in which the player assumes the role of Hairi Takahara. Much of its gameplay is spent on reading the story's narrative and dialogue. The text in the game is accompanied by character sprites, which represent who Hairi is talking to, over background art. Throughout the game, the player encounters CG artwork at certain points in the story, which take the place of the background art and character sprites. When the game is completed at least once, a gallery of the viewed CGs and played background music becomes available on the game's title screen. Summer Pockets follows a branching plot line with multiple endings, and depending on the decisions that the player makes during the game, the plot will progress in a specific direction.

There are six main plot lines to experience, which is increased to ten in Summer Pockets Reflection Blue. Four of the six plot lines are initially available in Summer Pockets, and seven of the ten plot lines are initially available in Reflection Blue. Throughout gameplay, the player is given multiple options to choose from, and text progression pauses at these points until a choice is made. Some decisions can lead the game to end prematurely, which offer an alternative ending to the plot. To view all plot lines in their entirety, the player will have to replay the game multiple times and choose different choices to further the plot to an alternate direction. All heroine routes are available when first playing both Summer Pockets and Reflection Blue. In both versions, each heroine will disappear from the game's title screen once her route has been completed. When all of the heroine routes in either version have been played at least once, an additional scenario called Alka is made available. Upon the completion of the Alka route, another scenario called Pocket is made available, which serves as the true conclusion to the story. In Reflection Blue, Umi's route becomes available after the completion of Pocket. In both versions, once Pocket is completed, all heroines reappear on the game's title screen.

There are two minigames featured in Summer Pockets and Reflection Blue. The first is a table tennis minigame that takes the form of a quick time event where the object is to click one of the circular indicators on the player's side at the moment when the ball hits it. Successive hits on any of the indicators will result in the filling of an intensity gauge and will increase the number of indicators from three to five which frequently change position. Successive hits on any one indicator will change its color from blue, to yellow, red, purple, and finally a multicolored "Super Shot!!" indicator. The accuracy of the clicks is scored from good, to great, and finally excellent. Play continues until either the intensity gauge is depleted, resulting in the player's loss, or until the player has accumulated enough points to knock out the opponent. In Reflection Blue, the table tennis minigame now also features doubles matches with the same basic mechanics.^[1]

The second minigame is an intricate catching and battling game called Islamon. There are 100 different Islamon to catch in 10 separate locations around the island with 20 kinds of bait. Any bait can be used in any location, but only one to four kinds of Islamon are available per bait, per location. The encounter rate for each Islamon also depends on the bait used in a certain location. For example, using Sugared Water in the Mountains results in a 25% encounter rate for a Cabbage Butterfly, but using the same bait at the Beach results in a 30% encounter rate for the same Islamon. The encounter rates for Islamon range from 5–100% (30 of the 200 permutations have a single Islamon that can be encountered). The player starts with three kinds of bait and three locations to set them. At first, the player can set two traps with bait per day, but this can increase to five per day depending on the player's rank.

A player can battle with their Islamon against an opponent twice per day, with each player allowed to use up to three Islamon per battle. Each Islamon has both a star rating from 1–5 and one of three types—Water, Wind or Earth—where Water beats Wind, Wind beats Earth, and Earth beats Water. Players customize their stock of available Islamon and choose which ones to battle with and in what order, but the rest of the battle occurs automatically. The goal of the battles is to increase in rank among 35 other individuals, and defeating an opponent will result in switching ranks with them. This continues until the player achieves rank 8, and from then on, the player can only gain one rank with each victory. Once the player defeats the players ranked 7 up to 2, the player can then battle the rank 1 opponent as the final boss. Unexpected events can occur during battle based on the relationships certain Islamon have with a given opponent.

Summer Pockets is set on an isolated, rural and peaceful fictional island on the Seto Inland Sea called Torishirojima.^{[n 15]} Among its residents is Umi Takahara, the daughter of Hairi Takahara and Shiroha Takahara (née Naruse). Shiroha possesses a cursed power that foretells her death and dies when giving birth to Umi. Fearing of Umi inheriting Shiroha's cursed power, Hairi takes Umi away from her hometown and forbids any connection with Torishirojima and her mother. This sabotages their bond, yet Umi still manages to sneak on the island and awakens her power, inadvertently travelling through time back to July 2000, when her parents first met.

The game starts in July 2000. Hairi Takahara uses the recent death of his grandmother as an excuse to come to Torishirojima to take care of her estate sale. Once there, he gets to know Shiroha Naruse, who can foretell the future and believes she is cursed and intentionally alienates herself. Besides Shiroha, there are three other girls who are the focus of the story. They include 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.^[2][3] Hairi also lives together with Umi under the pseudonym "Umi Kato". Hairi is never assigned the task of estate sale and instead dates the girls. Umi, in the meantime, repeatedly tries to approach her mother Shiroha without success, forcing her to abuse her power and relive the summer multiple times. During this process, her power is waning and she is constantly deteriorating.

After all heroines' routes are completed, the game automatically starts a new iteration of the summer of 2000. Umi's power has been severely weakened such that she can hardly make complete sentences. She insists on playing house with Hairi and Shiroha, on which they agree. Umi's true identity is also exposed to them accidentally. After the summer, Umi's power is depleted and she cannot materialise herself. She watches everything in spiritual form and hopelessly witnesses her mother's death, also discovering that Shiroha is not foreseeing the future. Instead, she is also stuck in a similar time loop that rewinds herself at death, and she is simply having flashbacks of events that happened in past loops. Realising that in order to save her mother she must prevent her from gaining the power in the first place, Umi gathers power from her bloodline and attempts one last rewind to Shiroha's childhood.

Umi arrives in Shiroha's childhood in an alter ego named Nanami. Shiroha has just lost her father in an accident, and her mother simply disappears shortly after. Taking shelter in Shiroha and her grandfather's house, Nanami accompanies Shiroha through her hardest time and successfully prevents her from gaining power. However, such action drastically rewrites the future, putting Umi's very existence at risk. Shiroha ultimately uncovers Nanami's identity, and Umi dissipates in her embrace.

In the new summer, Hairi arrives in Torishirojima to take care of his late grandmother's estate sale, but literally spends the whole summer doing so and fails to develop relationship with anyone. However, at the end of the summer he has a brief flashback of Umi and the past summers. He makes a last-minute decision on the departing ship to meet Shiroha, who later agrees to teach him how to make fried rice. An extended epilogue in Reflection Blue clarifies that afterwards Hairi and Shiroha still become a couple and Umi finally reunites with her parents who are alive.

Before the production of Summer Pockets began, Key was in the process of developing Angel Beats! 1st Beat (2015) and Harmonia (2016). At that time in early 2015, scenario writer Yūto Tonokawa was leading a new project for another visual novel, but this project was postponed to focus on Angel Beats! and Harmonia. Tonokawa later resigned from Key prior to the release of Angel Beats! 1st Beat in June 2015, and the project he was leading was subsequently abandoned. Following this, Kai was brought in to direct a new project, which would later become Summer Pockets. An in-house competition among Visual Arts employees was conducted to submit ideas for the new project as long as it was based around a concept involving an enjoyable, everyday life and a tearful story, but otherwise not being constrained by previous works by Key.^[2]

When discussion began regarding Key's new work, Jun Maeda talked it over with Takahiro Baba, the president of Visual Arts, and Maeda was adamant that the new project needed to make readers cry. Maeda went on to say that if their next work could not achieve that, it would mean the end for Key. Among the ideas was one submitted by scenario writer Yū Niijima described as similar to Ghost in the Shell by Kai. Although there were many ideas submitted, it was felt that they were all somewhat lacking as something produced by Key. Maeda admitted that although there were interesting ideas submitted, none of them would make readers cry. Despite Maeda not originally planning to submit an idea himself, he offered one as an example, but he was surprised when his idea was instantly accepted as the basis for what would become Summer Pockets. Maeda decided not to write the scenario for the game due to similarities in themes with Key's visual novel Air (2000), which he primarily wrote.^[2]

Kai began expanding on the concept with Maeda sitting in on production meetings, but Maeda was later hospitalized, leading Kai to request that more writers be brought on for the project.^[2] Niijima had previously worked on visual novels for Saga Planets, another brand under Visual Arts, but he resigned from Saga Planets in 2012.^[4] Baba had suggested on multiple occasions that they bring in Niijima for a new project, leading to him being brought in as a scenario writer. Another scenario writer, Hasama, was added following his contributions to the scenario of the ports of Key's visual novel Kud Wafter (2010).^[2] Kai wrote the scenario for Ao's route, Niijima wrote both Shiroha's and Kamome's routes, and Hasama wrote Tsumugi's route.

Although the game is set on a fictional island, it features locations based on real places; the development staff went to Naoshima, Megijima and Ogijima to aid in this process. The use of nostalgia as a theme was important for Kai who likened Maeda's concept to the Boku no Natsuyasumi video game series. In addressing concerns about its similarity to Air, which also features a rural, seaside setting during the summer, Kai noted that Summer Pockets will have a completely different feeling to it due in part to the relationships the heroines have among each other and also from several charming male characters being featured in the game, similar to that of Little Busters! (2007) and Angel Beats! (2010). However, Maeda pointed out that the theme of the maternal bond featured in Air is also included in Summer Pockets.^[2]

Na-Ga is the chief artist and character designer for Summer Pockets, and three other artists were later brought in to produce additional character designs: Yūnon Nagayama, Tsubasu Izumi and Fumuyun. Nagayama had previously worked on the character design for Angel Beats! 1st Beat, and she was asked to join the staff for Summer Pockets due to her art being highly compatible with Na-Ga's illustrations. Kai was introduced to Izumi by Harumi Sakurai, the voice of Yuri Nakamura from Angel Beats!, and Kai had wanted to work with Izumi on a project for some time.^[2] Fumuyun joined the staff to provide character designs for two supporting characters.^[5] Super deformed characters are designed by Engiyoshi. The game's soundtrack was composed by Key's signature composers, Maeda and Shinji Orito, in addition to Donmaru, Tomohiro Takeshita and Ryō Mizutsuki.^[6]

A nine-episode Internet radio show called Samapoke Kikikomi Radio (サマポケききこみラジオ, Summer Pockets Information Radio) featuring Visual Arts president Takahiro Baba was streamed on YouTube from February 27 to March 26, 2018.^[7][8] Leading up to the release of Summer Pockets, 53 artists drew illustrations of the game's characters and offered comments from March 1 to June 29, 2018, to promote the game.^[9][10][11] A full-color introductory booklet called Summer Pockets Walker was distributed for free at anime and gaming stores across Japan starting on March 30, 2018.^[12] To advertise Summer Pockets, J.I.O Create took a 2007 Honda Stream RSZ and made it into an itasha (a car featuring illustrations of anime-styled characters) with images of the game's heroines. The car was driven around and showcased throughout Japan between May 3 and June 8, 2018.^[13][14] The car was put onto the Japanese Yahoo! Auction website on July 26, 2018, and sold for ¥1,411,000.^[15] Illustrator Engiyoshi drew 17 snippets featuring characters from Summer Pockets called Summer Pockets Theater (サマボケ劇場, Samapoke Gekijō) from May 14 to July 5, 2018.^[16][17][18] A series of 12 short stories were released on the game's website between October 31, 2018, and December 24, 2019, written by the game's scenario writers: Kai, Hasama, and Yū Niijima.^[19][20][21] The stories, subtitled Natsu no Mabushisa no Naka de (夏の眩しさの中で, In the Middle of a Dazzling Summer), each focus on a separate character and feature illustrations by Fumuyun, one of the game's artists.^[21] The stories were later collected into a 144-page book with three additional stories and first sold as part of Visual Arts Winter Fes on December 20, 2020.^[22][23]

Key released a free game demo of Summer Pockets on April 24, 2018, on the game's official website.^[24] Summer Pockets was released on June 29, 2018, as a limited edition version for Windows.^[6][25] The limited edition came bundled with an official guide book titled Torishirojima Kankō Nisshi (鳥白島観光日誌, Torishirojima Sightseeing Journal), a remix album titled Swallow Tale, a rubber coaster, a microfiber cloth, a glow-in-the-dark sticker, and promotional cards from the Weiß Schwarz and Lycèe trading card games.^[25] Over two dozen stores in Akihabara and online offered special promotional items if the limited edition version of the game was bought at their store. These items included telephone cards, tapestries, mousepads, posters, a smartphone stand, and four separate drama CDs.^[25][26][27] The four drama CDs were later re-released with an additional drama CD titled Summer Pockets Drama CD Collection at Comiket 95 on December 29, 2018.^[28]

The special edition was also bundled with an art book, an acrylic stand, a mini plush toy of Inari, a T-shirt, a necklace, a book jacket, and a Summer Pockets holographic card set.^[34] Leading up to its release, 23 artists drew illustrations of the game's characters and offered comments from March 3 to July 2, 2020, to promote the game.^[35][36][37] There were also five short one-shot manga drawn by separate authors released from June 4–22, 2020.^[35][38][39]

Originally conceived as a fan disc, Key later decided to release it as a new version of the game with various additions, and it is made by the same staff as the original game. Reflection Blue has four additional routes: two heroine routes for Miki Nomura and Shizuku Mizuori from Summer Pockets, a route for the new heroine Shiki Kamiyama, and a separate route for Umi Kato. Kai wrote the scenario for Miki's, Umi's and Shiki's routes, and Hasama wrote Shizuku's story. There are also new everyday life scenarios featuring the characters interacting and having fun together, and this includes an upgrade to the table tennis minigame.^[1] A 224-page art book titled Summer Pockets Visual Fanbook was released on May 24, 2019, by Visual Arts.
