The [gameplay](/source/Gameplay) in *_Summer* follows a plot line which offers pre-determined scenarios with courses of interaction, and focuses on the appeal of the six female main characters. The story revolves around Takumi Kaizu, who after years of making good friends, many of whom are female, is asked by his best male friend Osamu Funada if he likes anyone. With his last summer in high school quickly approaching, Takumi decides to find someone to like by the end of summer vacation. *_Summer* has had overall well received sales, premiering as the most sold [bishōjo game](/source/Bish%C5%8Djo_game) in Japan during the first half of July in 2005, and would go on to chart twice more.

*_Summer* has made several transitions into other media, such as a mini [four-panel](/source/Yonkoma) [web comic](/source/Web_comic), a [manga](/source/Manga) [one-shot](/source/One-shot_(comics)) published in [Kadokawa Shoten](/source/Kadokawa_Shoten)'s *[Comp Ace](/source/Comp_Ace)* magazine, and four character [light novels](/source/Light_novel) written by [Jōji Kamio](/source/J%C5%8Dji_Kamio). An illustrated story titled *_Summer## Official Illust Story* was serialized in [MediaWorks](/source/MediaWorks_(publisher))' *[Dengeki G's Magazine](/source/Dengeki_G's_Magazine)*. A two-episode [original video animation](/source/Original_video_animation) was produced; the two [DVDs](/source/DVD) were released on October 27, 2006, and January 26, 2007. Several [drama CDs](/source/Drama_CD) were released based on the game, including one released as a prologue to the OVA.

## Gameplay

*_Summer* is a [romance](/source/Romance_(love)) [visual novel](/source/Visual_novel) in which the player assumes the role of Takumi Kaizu.[1] The gameplay requires little interaction from the player as most of the duration of the game is spent on simply reading the text that appears on the screen; this text represents either [dialogue](/source/Dialogue) between the various characters, or the inner thoughts of the protagonist. Every so often, the player will come to a "decision point" and must choose from options that are displayed on the screen, typically two to three at a time.

During these times, gameplay pauses until a choice is made that furthers the plot in a specific direction, depending on which choice the player makes. There are six main plot lines that the player will have the chance to experience, one for each of the heroines in the story. In order to view the six plot lines to their entirety, the player will have to replay the game multiple times and choose different choices during the decision points in order to further the plot in an alternate direction.

Throughout gameplay, there are scenes depicting Kyōtarō and a given heroine having sex.[2] However, in the [PlayStation 2](/source/PlayStation_2) port, these scenes are removed. The visual novel also features real-time choices (RTC), this is when the player given a choice within a time period, and varying on the amount of time the player takes to make the choice, it will effect the ensuing dialogue.[3]

## Plot

### Story and setting

*_Summer'*s story takes place in a small seaside town during the summer,[1] where Takumi Kaizu is a normal high school student enjoying his final year in school with the rest of his friends.[1] Over the years, he has made good memories with these friends of his, most of whom are girls, though apparently still have no overt feelings of attraction towards any of them.[1] There are six main potential love interests presented to Takumi in *_Summer*; they are Konami Hatano, Shino Ebizuka, Sana Kaizu, Chiwa Amano, Wakana Shimazu, and Hinako Nanao.[1]

Konami is the kind and timid childhood friend of Takumi, and the main heroine.[4] She will come to Takumi's house in the morning and prepare breakfast for him.[4] As a contrast to Konami's gentle personality, her female friend Shino is rough and hot-tempered, but protective of Konami.[5] Takumi has a younger stepsister called Sana, an energetic, fun-loving girl, if not a little lazy for being unable to wake up in the morning without Takumi.[5] Sana has a best friend called Chiwa, a mysterious and very strange girl, who is known to be unpredictable.[6] An upperclassman called Wakana has an immense crush on Takumi, despite her popularity with boys due to her beauty and elegant personality.[7] The homeroom teacher of Takumi, named Hinako, will often be seen trying to find free food because of her money wasting.[8]

When Takumi is asked by his best male friend Osamu Funada if he likes anyone, Takumi starts to think about it though is still confused on what to do next.[1] With his last summer in high school quickly approaching, Takumi decides to find someone to like by the end of summer vacation.[1] Takumi slowly starts to take a romantic interest in the girls around him, while his friend Osamu relentlessly searches for a girlfriend as well.[1]

**Shino Ebizuka (海老塚信乃, *Ebizuka Shino*)**- [9]
- Shino is Konami's closest female friend who has a tough personality.[5] She often acts in ways to defend Konami or react strongly on her behalf when she will not speak up over certain matters.[5] She has shown herself to have a temper and often will get angry at Osamu's repeated perverted actions, which often earns him a beating on Shino's behalf.[5]

**Sana Kaizu (海津沙奈, *Kaizu Sana*)**- [9]
- Sana is Takumi's younger step-sister by one year who lives with him, though there is no blood relation between them.[10] She most often has an active personality when awake, though still has problems getting up for school during the week despite now being in high school.[10] Her best friend is Chiwa Amano who hangs out with her constantly.[10]

**Chiwa Amano (天野千輪, *Amano Chiwa*)**- [9]

**Wakana Shimazu (島津若菜, *Shimazu Wakana*)**- (OVA)[9]
- Wakana is a very beautiful girl who is one year above Takumi.[7] She seems to have a [crush](/source/Limerence) on Takumi, of which he is unaware of.[7] At school, Yuno Kawakami will often follow her around either helping her out with simple things or by fending off pushy guys with a wooden sword.[7]

**Hinako Nanao (七緒日向子, *Nanao Hinako*)**- [9]
- Hinako is Takumi's homeroom teacher.[8] She is apparently hooked on buying strange and often useless mail-order products with the money she earns in her job.[8] Since most of her money is spent in this fashion, she is usually found wandering the halls of the student cafeteria during lunchtime in hopes of getting free food.[8] Hinako has a teacher friend called Kasumi.[11]

#### Supporting characters

**Yuno Kawakami (川上由乃, *Kawakami Yuno*)**- [9]

**Ochimusha Master (落ち武者マスター, *Masutā Ochimusha*)**- (OVA)[9]
