Suika is a Japanese adult romance visual novel that tells the story of several young people in the remote village of Tokiwa over a two-week period. The player takes on the role of different protagonists, each with their own story to tell, as they navigate their feelings for one another under the warm summer sun.
The gameplay involves classic visual novel mechanics, offering a predominantly text-based experience with character illustrations and backgrounds. The player's choices at key narrative junctures influence the direction of the story, leading to multiple branching paths and various endings. Voice acting is used for the female characters in this game.
The initial Windows versions and the OOParts version contain scenes with explicit sexual content, but later versions and console releases omit these scenes, replacing them with alternative scenarios and graphics.
The game begins with Hiroshi Inaba's prologue, where he reflects on his worries about his sister Chitose before meeting two local girls, Itsuki Minase and Sayaka Shirakawa. He then encounters a girl with long silver hair who runs away from him.
Chapter 1 follows Akira Kazama as he returns to Tokiwa and reunites with Itsuki Minase at the village shrine. A love triangle forms between them, their friends Sayo and her sister Sayaka, and Akira must decide where his true feelings lie. Chapter 2 stars Sōji Kamishiro and Sayaka Shirakawa as they bond over painting while Ritsu's father runs his studio. This trust brings them closer together.
Chapter 3 is about Yoshikazu Masaki, who secretly harbors feelings for his sister Akane. His girlfriend Tōko Kyōya drives a wedge between him and his sister, forcing him to choose between them.
Chapter 4 returns the player to Hiroshi Inaba's prologue, where he meets the silver-haired girl again and uncovers a shocking truth.
