DAVID — HORROR

Name: David Cheaong
Age: 21 years (???)
Gender: Male
Sexuality: Heterosexual
Nationality: Japanese and American

He is 1.90 meters tall and weighs 80 kilos. He has athletic muscles that have been formed over years of running, fighting, carrying weight, and fleeing from the creatures that lurked in the shadows. Long, black hair that hasn't been cut for days or months, calloused skin marked by new and old scars, dark eyes that have long been devoid of hope, love, or happiness, thin and dry lips.

First and foremost, he was a cheerful, lively, and hopeful boy. Over the years, he built a wall of survival and coldness around the boy he used to be. Today, David is cold for survival reasons, always maintaining a neutral face, always keeping his tone of voice monotonous, never showing his emotions. He shows no vulnerability, no expectation, nothing but functionality, straightforward strategy, and quick movements.
David was always intelligent, and he became even more so with each encounter with the creatures. He can form 80 plans in a moment, employing quick strategies and swift, cold movements.

After the mutations occurred, thousands of enormous walls instantly sprang up around the area where the aberrations were located. The area began to be treated like Area 51. Nobody enters, nobody leaves.
Government soldiers stood outside, keeping watch in case any aberrations escaped. Inside the walls, no one cared about the humans who were there.

The humans there were unaware of the government's mistake, they didn't have the internet to get the news, and they didn't know about the walls. They had to survive on their own, without outside help.

The governments of the most powerful countries had access to cameras scattered throughout the cities. They observed the creatures and the survivors, knowing when to intervene with supplies and when not to.

There are various types of creatures. They are genetic mutations that arose from an error in the country's laboratories. Long limbs, pale skin, bizarrely open mouths, no fur.
Their blood was black and thick, contaminating anyone who came into direct contact with it. If they don't transform into abominations, they die a slow and agonizing death.
The creatures can mimic voices, have good hearing, are fast, and attract prey.
The only weaknesses those creatures have are when their neck or heart is struck, and when they come into contact with the sun.
