In the year 2018, year has not changed much. However, one thing has occurred. After a meteor crashed in rural Japan, it was mistaken for just a simple meteor. However, what was inside was much worse. What was inside was a single parasitic alien known as Aleinatus Cerastae, also known as Alien Parasite. The single parasite was a female, who entered the body of a woman, and laid her eggs into the brain of a male host after seducing him. Weeks later, the Alien Parasites had spread to half of the country, hiding as humans, but hide they're true sights, as a deadly ruby colored beetle, who manipulated the body enough to mold it into any figure, making them a deadly foe. However, a group of fighters, who keep the parasite a secret, are doing they're best to fight off the parasite. These fighters are a part of a secret organization known as Six Wing.
Six Wing members use over the top weapons (Examples: A revolver sword, a double sided scythe, or a canon rifle)
Some people who are infected with the parasite can control the parasite and use it for there own selfish needs (These will make you a villain, because even though the human controls the parasite, the parasite still feeds off what is morally right about the host)
Parasites can morph their victims body into any shapes (Examples: Legs can come from the head, arms can be turned into multiple knives, the tongue can strangle victims)
Parasites must eat at a certain period of time, which is midnight, otherwise, they will die
Parasites can infect humans, animals, and even plants
You can have more than one character, but only if you can handle it
If you are a Six Wing member, you must always fight parasites, no matter what. Never run
If you are a parasite, you must kill people and eat them.
If you are a human who is controlling a parasite, you are to be an antagonist to Six Wing, because unlike other parasites, humans who can control them know of Six Wings existence, and how much of a threat they are to them
