Angel hearts

Released in 1989 by Elf for the PC-8801, *Angel Hearts* is a notable early example of a school-themed RPG that pioneered the "bishoujo" subgenre. Players control a protagonist who infiltrates a mysterious academy as a janitor to rescue missing students and dismantle a clandestine organization known as "Seitokai." The game features a straightforward exploration system paired with turn-based combat, incorporating unique thematic elements that defined the stylistic evolution of adult PC adventure gaming in the late 1980s. As a historical artifact of the retro Japanese PC era, it reflects the creative experimentation of its time, blending narrative-driven quests with focused character-based encounters.

In this 1989 role-playing game, a series of mysterious disappearances at an all-girls academy prompts the school's newspaper club to investigate a secret organization known as "Seitokai." The protagonist, Mii, is hired to infiltrate the school undercover as a custodian to rescue the missing students and dismantle the organization. Throughout the academy, Mii must confront students who have become hostile, battling through turn-based encounters to uncover the truth behind the school's dark secrets.
