About Female Spy Undercover Investigation: Holy Sex Academy
Female Spy Undercover Investigation: Holy Sex Academy is a 2D RPG Maker infiltration game by nullnullfullido. You play Mashiro, a female spy whose family technique blocks sexual sensation, making her resistant to erotic training and combat.

The story emphasizes corruption, exhibitionism, and humiliation as she attempts an undercover investigation against traps and opponents.
The current build is v1.04, released on May 8, 2025, and development remains ongoing rather than finished or a demo. It runs on Windows in English and uses censored mosaics. The game is a Japanese-made 2DCG title with RPGM systems and a 2D computer graphics presentation.
Developer's description
A clueless female spy undergoes sexual development and training in this exciting infiltration RPG! Our protagonist, a female spy named "Mashiro," was born with a body that cannot feel sexual sensations due to a secret technique passed down from her family. Since she is invincible and oblivious against all things sexual, she regularly achieves overwhelmingly positive results in both erotic training and erotic combat. However, when she infiltrates an educational organization, the "Academy of Erotic Arts," her insensitivity seal is removed by the enemy leader! Spoiler Her first time feeling sexual pleasure... Her first sexual climax... And, for the first time in her life, a sexual desire surges up within her...! The nasty, lustful traps and enemies won't show mercy to anyone, not even to a female spy who knows nothing about erotic things! With her immaculate female body now completely unresistant to lewd attacks, and her sexual knowledge completely ignorant of lewd things in general, will Mashiro really be able to successfully complete her undercover investigation...!?
