This series contains mountains of spoilers for the main plot and all character subplots of Gakuen Heaven 2.
Luckily, GH2 translations and information are available on our translation site here! → Welcome to Heaven
Familiarity with the plot of GH2 will enhance your enjoyment of these stories. I strongly recommend reading Tomo's route, Sakaki's route, and Sonoda's route.
Please note: All of my GH fic is based on the original source - the PC game series. Nothing is based on the anime or any version of the manga. The most important difference is that Dr. Matsuoka never kidnapped Keita or took any other vengeful actions agains Suzubishi; instead, his issues were resolved purely by talking it out with Keita and Kazuki.
