Debut 21

Debut 21 is a futuristic spinoff/spiritual successor to Tanjō: Debut; as with that game, the player is tasked with raising an idol as they become popular and managing their stats, but the twist here is that the game is set in the year 2020, and the idol you are tasked with managing is an android, named Ai Kanzaki. The player is tasked with guiding her through an entire in-game year, raising her stats and keeping her stress level within reasonable limits. In contrast to its 2D predecessor, this game uses real-time 3D graphics.
