The protagonist is Mashiro, a female spy whose body was made unable to feel sexual pleasure from birth due to a secret technique passed down through her family.
Invincible against sexual attacks, she spends her days achieving overwhelming success in erotic combat and erotic training.
However, in the school management organization "Erotic Arts Academy" that she infiltrates this time, the enemy's leader breaks the spell that made her frigid!
She feels sexual pleasure for the first time.
She reaches a sexual climax for the first time.
And for the first time, sexual desire surges within her, overwhelming the female spy...!
Erotic enemies with ruthless erotic traps show no hesitation even to a female spy who is a novice in erotic experience!
A young female body with no resistance whatsoever to lewd attacks, she is... With her utterly ignorant sexual knowledge, will Mashiro be able to successfully complete her undercover investigation...?
She transfers in as a student to investigate the true nature of a school rife with dark rumors, engaging in espionage.
However, the school's educational scenes seem strange...
It appears that only lewd content unfolds, and she is unwillingly forced to learn about sex firsthand.
Finally, she is subjected to unreasonable punishments...
As she repeats her daytime school life and nighttime undercover investigations, the female spy's body undergoes lewd development, and these lewd sensations begin to follow her even in her daily life...
At this rate, her body will be ruined by sexual arousal before she can expose the evil deeds... She must do something before her true identity is revealed!

“Wouldn’t it be a waste to simply trap and kill a woman that fine?
Crush her confidence, her dignity—over and over again.
Grind her down completely, until she’s worn out and begging,
bowing her head to me repeatedly.
I’ll carve the ‘true role of a female’ into her body, one piece at a time.
How does that sound?
Doesn’t it make your heart race?”
Betray your “ally” by siding with the “enemy”!
The ultimate corrupt power-move!
Until the title of “Strongest War Princess” is wiped from people’s memories,
drown her in defeat and disgrace.

A teacher Saki Niiyama is r*ped by a certain student after school.
Since then, her life is turned into days of humiliation...

Mech Academy is an adult visual novel based on multiple-choice decisions. The player will assume the role of the protagonist in this story and will encounter "several characters, and try to develop your relationship with them. The player's decisions will have an impact on the evolution of the story.
 
"It's the year 2175, and you are the pilot of a Guardian Mech. These are gigantic war machines built to defend Earth from the Noxa, a ruthless alien race intent on conquering your planet. However, you don't belong to this time; you are actually Lieutenant Knight, a highly decorated soldier who lived in the 1970s. Due to a mysterious experiment, you have been catapulted two centuries into the future. Everything is new and complicated for you. Your world, the society in which you grew up, is profoundly different from the one you find yourself in now."
 
Following a bizarre series of interconnected events, you have been chosen as a pilot. Your new home is now Section 2, a training center led by Elara Sardana, a captivating commander who is as strict as she is attractive. Elara is a hybrid, half-Earthling, half-alien.
 
You are not the only pilot at the base;
Mei Maede is a rebellious girl with a sensual attitude. From your first encounter, she will show a strong attraction toward you.
Drana, on the other hand, is a Vorlanian, a princess from a people light-years away from Earth. Drana pilots the Ghost Mech. It will be very difficult to establish a good relationship with her; her strong, determined, duty-bound, confrontational, and especially hostile attitude toward you won't make life easy, but it will certainly be worth trying to win her over.
Lydia Helmer is a dark-haired girl with a delicate face. Lydia is the fourth pilot from Section 2. Like Drana, she also doesn't hold you in high regard. Lydia is a very reserved, shy, and closed-off girl. Getting her to open up to you won't be easy, but when she does, it will make you very happy.
Irina is the chief scientist. she is very intelligent, a genius, but she is also very distracted and forgetful. She has a too-accommodating nature.
 
In Mech Academy you'll have the opportunity to meet many beautiful women, all with complex and well-defined nature and behaviour. Interacting with them, seducing them, making them fall in love with you, will not be so easy and straightforward. Especially because you will be busy defending Earth from extraterrestrial invaders!
