First Limit

The first game in the series. Sora Hashiba was put into the hospital for quite some time after falling from one of the school buildings. He didn't receive any major injuries, but he has lost some of his memories in the process. However, he continually sees a vision of him being carried through several dark corridors and the voice of someone calling out to him. After being released from the hospital, Sora heads back to the dorms to find that a new boy by the name of Sunao Fujimori, who will now be his roommate. He is told that Sunao is his childhood friend, but he cannot recall spending his childhood with Sunao. As he spends time with Sunao, he notices some strange things about him, including his transformation into his alternate personality Ran. On top of that, the spirit of a hospitalized schoolmate possesses Sunao and confesses his love for him. Depending on the player's decisions, Sora can either end up with Sunao, Hiromu, Ran, or Minato.

Target Nights

After spending some time in Shin-ichirou and Nanami's place, Sora and Sunao come across a mysterious cosplaying bandit known only by the number 416. He claims that he has come to take away something precious from Sora. Meanwhile, Sora and Sunao meet Chris, who works at the nearby church. While he seems harmless, he begins to spend more time with Sora. To top it all off, Sora begins to realize that there are times when he and Sunao are mysteriously in bed together. He already knows about Sunao's connection with his alternate personality Ran, but could that mean he has his own alternate personality as well? Depending on the choices of the player, Sora will either end up with Sunao, Chris, Ran, Matsuri, or Minato. Also, obtaining all the CGs rewards the player with a special ending involving bandits 416, 773, and most recently 848.

Rain

Possibly the turning point in the series. Sora and Sunao continue their life in school. All seems normal until Sora notices a child that looks very similar to himself. Also, some of his schoolmates are beginning to act a little strange. Even Sora begins to notice that something odd about his connection to Sunao and the relationship between their alternate personalities Yoru and Ran. Depending on the choices of the player, Sora may end up with Sunao, Matsuri, Soushi, or Minato. Collecting all the CGs allows the player to access secret endings that involve Sora, Sunao, Matsuri, Shin-ichirou, and Nanami banding together as cosplaying bandits 848, 370, 332, 416, and 773.

White Flower

The final game in the series. Taking place a couple of years after Rain, many changes have been made to the school. Not only is it no longer an all-boys school, several of the former students are now working as teachers while others move onto other jobs. Sora, as one of the teachers, has been living a fairly normal life as he takes Minato's place as teacher. However, he realizes that it won't stay normal for long when he sees that Sunao, who he has not seen since the events in Rain, reappears in one of the halls. This game finally wraps up the story between Sora and Sunao and ends their conflict with Professor Aizawa. Depending on the player's choices, Sora can either end up with Sunao, Nanami, Hiromu, Matsuri, Soushi, or Minato. There are two hidden endings in this game. The Yoru/Ran ending is received when achieving the true ending, while the Kaito ending is obtained when all the CGs are collected.

Mou Matte

A spin off of the Sukisho games. Takes place some time in between Rain and White Flower. The player now controls Gaku Ichikawa, one of Sora's friends who worked in the Chemistry Lab. Gaku must now choose whether to continue his relationship with Kai Nagase or start a new one with Ren Shiina. Depending on the player's choice, Gaku may end up with Shiina, Nagase, or Kitamura. Most of the main cast from the previous Sukisho games are visibly absent, including Sora and Sunao. Of the original cast, only Gaku, Nagase, Shiina, Kitamura, Nanami, Nakahara, and Hano make appearances.
