Ambitious Mission

Ambitious Mission is a Japanese adult visual novel centered around phantom thieves.

The player controls Mikage Nezu, a high school student who unexpectedly crosses paths with a phantom thief, Miss Arte, and correctly deduces that she is actually his classmate, Kaguya Arise. In order to keep Mikage from revealing her secret, Kaguya tries to recruit him into a thieves' guild that she is putting together, but things don't go exactly as planned. Nonetheless, as Mikage continues to put his skills as a thief into practice, he crosses paths with Kaguya again and eventually decides to join her on her escapades.

The player's decisions throughout the game may cause the story to branch into different routes and result in different endings. These decisions may cause Mikage to grow closer to Kaguya or one of the game's other three heroines: Kaguya's wheelchair-bound sister Atena, Mikage's stylish classmate Nijimu Hongou, or the tenth grader Yae Ishikawa.

The Windows version of the game includes scenes with sexual content which were omitted from the console versions.
