Gakuen Heaven is a media franchise originating from the PC game Gakuen Heaven: Boy's Love Scramble, originally released by the company SPRAY. The franchise gradually expanded to include more games, drama CDs, manga, and anime.

Gakuen Heaven - Boy's Love Scramble Type B: In the game, the player Keita Ito suddenly received an acceptance letter from the renowned Bell Liberty Academy (also known as BL Gakuen). Attracted by the prestige of the school, he decided to attend. However, on the day of his transfer, the bridge joining the school and the academy, which was located on a remote man-made island, suddenly raised and his bus fell. Luckily, no one was injured but the accident aroused the attention of both the student council's president Niwa Tetsuya as well as the head of the accounting department Saiyonji Kaoru.

CHARACTERS:
- Keita Ito: Voiced by: Fukuyama Jun
During the middle of the school year, he received a letter of admission from Bell Liberty Academy. Though he seems to be an average guy without any sort of special skills, he is a very warm and friendly person. The only skill he thought he had was luck.

- Kazuki Endo: Voiced by: Sakurai Takahiro
He is Keita's classmate and the first friend Keita makes at BL Academy. He leads a double life as a student of BL Academy and as its chairman. The last wishes of the school's late chairman, Endo's grandfather, were for Endo to succeed his position. Endo's innocuous and perpetually friendly demeanor does not betray the fact that he is also an excellent executive. Endo is also a part of the school's handicrafts club. He is actually Keita's childhood friend who promised in the future that they could go to the same school.
