Akaneiro ni Somaru Saka

An average conversation in Akaneiro ni Somaru Saka featuring the main character talking to Tsukasa.

Akaneiro ni Somaru Saka's gameplay requires little interaction from the player as most of the duration of the game is spent simply reading the text that appears on the screen which represents either dialogue between the various characters or the inner thoughts of the protagonist. Every so often, the player will come to a point where he or she is given the chance to choose from multiple options. The time between these points is variable and can occur anywhere from a minute to much longer. Gameplay pauses at these points and depending on which choice the player makes, the plot will progress in a specific direction. In the original version, there are six main plot lines that the player will have the chance to experience, one for each of the heroines in the story. This number increases to seven with the PlayStation 2 version.[1] To view all the plot lines, the player will have to replay the game multiple times and make different decisions to progress the plot in an alternate direction. One of the goals of the gameplay from the PC version is for the player to enable the viewing of sex scenes depicting the protagonist, Jun'ichi, and one of the six heroines having sex.

Jun'ichi Nagase attends a prestigious high school. He has the nickname Geno Killer since he was rebellious in middle school. This is used, inadvertently, to help a girl named Yuuhi Katagiri from trouble. She later transfers to his school. Jun'ichi then kisses her due to a misunderstanding. Outraged, because he stole her first kiss and embarrassed her, she screams at him. Subsequently, it turns out that Yuuhi is his fiancée as arranged by their parents. Their parents discuss the matter and order them to go out together for a month to restore their relationship. If their relationship does not get better, the engagement will then be cancelled.

Voiced by: Wataru Hatano (anime)

Jun'ichi is the main protagonist of the series and is a second year high school student. He had a reputation of a delinquent in junior high school until his sister, Minato, decided to move in with him. He has a snarky attitude and is often teased by everyone around him, including his teacher. His life takes a drastic turn when Yuuhi Katagiri enters his life. They first meet when he saves her from some delinquents who were bothering her. The following day she is introduced as a transfer student to his class. Due to a misunderstanding, he kisses her in front of the class causing her opinion of Jun'ichi to sour. This is further exacerbated when it turns out that their families have arranged their marriage. Despite this rough start, Jun'ichi finds himself protecting Yuuhi when she is harassed and, as time progresses, their feelings for one another begin to grow even though neither of them will admit it. Throughout the anime series it is hinted that Jun'ichi has romantic feelings for his sister, Minato, but is reluctant to admit this even though he sometimes has fantasies about her. In the final episode, he realizes that he cannot live without Minato and confesses to her. In the manga however, he and Yuuhi end up together, as he also has feelings for her.
