Chet/Chloe

The main protagonist of the story. A high school student working at a carpet store who is "definitely over 18 years old" and likes playing pokemon on an emulator on his/her phone.

The prologue begins with some exposition about the player's dull life and the alien abduction that interrupts it.

Part 1
Starting the story at part 1 you chose your gender, while working at your crappy job you are surrounded by a strange light. You wake up on an operation table with your lower half exposed. You are in a space ship and had been abducted by aliens, you get up to find a strange parasite squirming up your leg and infect you. After you see an unconscious alien doctor and take her jumpsuit and start your adventure.
 * If you start as Chet (male) the parasite will enter your Anus
 * If you start as Chloe (female) the parasite will enter your vagina

Part 2
In part 2 you'll wake up in your bedroom from a strange dream and find a canister containing a parasite. Using them on yourself and others can arouse the suspicion of those around you in authority... but you can do anything...

Part 3
By Part 3 you are now Chloe a female, if you ever even were male to begin with. You know what must be done. You must stop the aliens that now threaten your life by using their own parasites against them. They have demonstrated they will not sit idly and leave well enough alone and you have the briefest of windows to surprise them. You arrive with your minions at the Antari Research Facility intent on ending the werm project.

Part 4
Tragedy has struck. Injured and alone, Chloe is now a werm herself and must decide whether to remain in her damaged body or choose a new host. Both choices lead to an unappealing reality - exile. Alone and empty-handed the player washes up on the shores of Kimelea on the planet Seneton, a core world in the Antari Imperium. In this strange place you must heal and rebuild and hope that a way exists back home.

Part 5
Now armed with a mutated plant in your body you finally have a way to exert a degree of control over the parasites. It has been a year and the werm project is still actively pursuing you. As part 5 opens your return home is cut short when you are abducted again! This time by uninfected human resistance fighters. You appear weak so instead of killing you they decide they will interrogate you instead. Man they really don't know who they're dealing with!

Trivia
Chet/Chloe's character may be a comment on the pressures thrust upon today's youth. The player is juggling a job, school, a social life all while in a single parent household where 2 grown siblings also live. Life feels meaningless yet is supposed to have unlimited potential and purpose. In the prologue(s) we are privy to the mental struggles that Chet/Chloe faces:

- "You can do anything. That's what people say.  But do they mean it?  Surely they don't mean anything, in the strong sense of the word.  Are they telling you that you can be lewd?  Have you ever heard someone say "you can do anything... now go get a gender change, a rubber horse cock, a Cleopatra wig and move to Florida"?  Does that even make any sense?" -Prologue when starting from part 2

To many young men and women coming of age is focused on sex and that power or powerlessness it can represent. In the story Chet/Chloe finally achieves purpose and relevance through the parasites which are a symbol of sexual power. Before being abducted he/she feels like life is happening all around them and they are missing it. All across the universe creation and destruction occurs every second but he/she is trapped in the routine of going to school. Spreading werms unlocks the world though and suddenly Chloe is a player on the stage of life able to affect anything she touches. Powerful allies and enemies are drawn to her and for once she is important. She is freed from her bonds able to decide for her own whether to spend her life fighting the werm project or drowning in the control of a stronger being, becoming a mindless sex puppet and letting them take control. Any fantasy she has she is free to live out, whether it be turning her best friend into a girl or having her own mother fuck her brains out literally.

Though the prologue says the player works in a carpet store, after the abduction no return to work is ever made.

Both Chet and Chloe must respond that they are homosexual in order to advance Tracie's infestation arc. The game does not ever specifically comment on the main character's sexual preference and Chet/Chloe never express disgust towards homosexual acts. It is possible both are bisexual if not outright gay.

Several times the game reminds you that the player as well as other high school students are "definitely over the age of 18." This would be highly unlikely in most countries including the United States. In most countries around the world a student in high school would only be over the age of 18 if their educational advancement was delayed in some way. It is much more likely to be exactly 18 or possibly a bit younger. This repeated phrase is clearly inserted due to the sexual nature of the game's content.

Chet/Chloe and Tracie are the only characters in the entire game who become a parasite host willingly... And Tracie is insane.
