Uchuu Youhei Alicia Story

Alicia gets captured by aliens from Uchuu Youhei Alicia

In a world where space travel has been long-achieved and aliens exist together with humans, Alicia, a skilled mercenary and our star of the story, is sent on a mission to rescue the president’s kidnapped daughter (Mia) from an alien slave colony. However, soon upon arrival, our heroine gets captured. Due to Alicia’s excellent genes, she gets turned into a tool for a scientific sexual experiment carried by her captors which involves lots of alien rape.

The alien colony to which Mia was sold as a slave acts as a base of operation for human experiments. Here those unfortunate enough to be sold have to go through countless sexual experiments which test the limits of the female human body and their capability to act as hosts for alien birth.


Alicia is a space mercenary wearing tight sexy skin-suit power armor. Due to her superior gene bestowing her the ability to regenerate, she is an ideal subject for the human experiment program carried by the aliens in the sex slave colony.

When the news of Mia being abducted by space pirates came to pass, Alicia took the news quite personally. Despite being a mere mercenary for hire, Mia is not just any girl to be rescued, she is like a little sister to Alicia as the two share a history together. Because of this, without wasting any time, Alicia did not hesitate to go alone, but like many before her, she also ended up getting captured…

Alicia Infiltrating Alien Sex Slave Colony


Mia is the daughter of the president of the Galactic Federation who got abducted by space pirates and sold to an alien slave colony. She is an honest person beloved by her people, though a bit ignorant of the ways of the world. Mia’s pure childlike innocence is on the verge of being corrupted by the slave colony’s ruler Gagandi.

Jawa is an alien that resembles something of a reptile. He is the person entrusted to manage the reproduction experiment program carried in the slave colony. Thanks to his brilliant mind and passion for Earth and its literature, Jawa has enriched his life with the knowledge of the human language, thus making him capable of communicating with Alicia unlike the rest of his fellow aliens around him.

Gagandi is a giant repulsive-looking alien and the ruler of the slave colony. Incapable of speaking the human language, he leaves the translation work to his subordinate Jawa. To pass time, Gagandi has found female creatures of different species as a form of hobby, sexually tormenting and impregnating them for his own sadistic pleasure. Female humans from planet Earth are especially to his liking.

Uchuu Youhei Alicia Gameplay

Choose your alien sex scene from Uchuu Youhei Alicia

In Uchuu Youhei Alicia there is no actual gameplay, as can be expected from many Japanese erotic visual novels. However, what you are given is a simple H-scene selection screen that takes you to different sexual experiments featuring Alicia and Mia. As you go through the experiments, new ones get unlocked automatically.

Below the selection screen is three green progression bars indicating Alicia’s status. These have no real meaning other than showing the player Alicia’s process of changing both mentally and physically. From top to bottom, the green bars show Alicia’s subordination, pleasure, and the physical remodeling of her human body.

Whether you are a slow or a fast reader, the game gives you the ability to change the speed of the displayed text. You can also change the volume of character voices and the background music. For easy read and comfort, there is an auto-read feature. When finishing your session, the game can be saved and continued from where you left off. There is also a text log to access what has been said previously if you missed something and the possibility to skip text and go through the story in the blink of an eye if so desired.
