Parasite

Mark Keyvel: the leader of an organization that eradicates parasites that are currently a threat to humanity. This organization is called Killer Parasite (KP).

Mark no longer has any family members, because his mother has become one of the parasites & has slaughtered all of his family members, which forced Mark to use his own mother as a tool to detect the presence of parasites that have been living around humans at this time.

Mark has jet black hair, piercing brown eyes, 183cm tall, & a charming, stiff face that always has a flat expression.

The KP organization has strict rules, if they add members, namely by checking the entire body with a body scanner, to find out whether the added member is a human or a parasite.

However, they also know how to detect parasites, by plucking a strand of hair, if it shrinks then it means this person is a parasite, and vice versa.

Parasites originally lived in the deep ocean, but eventually they came out to the surface to dominate the entire earth, by entering the ears or noses of humans to eat their brains, then making them hosts to survive on earth.

Moreover, the Queen parasite is the only single organism that controls all the parasites, because she creates all the parasites from her own cells.

The parasite queen is named Tamaka, and she is no ordinary organism, because she has lived for millions of years, & this time she wants to take over the entire earth.

Tamaka is much stronger & his body system will also reassemble, even if it has been burned or cut, because his body regeneration is stronger & not like other parasites.

Tamaka is smarter, he divides many groups of parasites to enter many humans, & every leader he has appointed, is also equally strong & clever to manage each group.

In fact, each group leader cannot attack the Queen, because she will always eat every rebellious parasite & also make more eggs to be left to become zero parasites that repeat everything again.

Tamaka is much stronger, & he can't be stopped by anyone, except being frozen like millions of years ago.

However, each parasite also has its own mind & its own name, which has been given by Queen Tamaka.
